Résumé :
The article contains the review and analysis of data on the mechanisms of the toxic action of carbon nanotubes (CNTs) on the body and available results of CNT toxicological evaluation after inhalation and oral routes of the action. Identification of cellular and molecular mechanisms of CNTs toxicity allows to justify the list of the most sensitive biochemical toxicity markers that could be used for monitoring the occupational effects of CNTs and serve as a promising target for the corresponding pharmacological and immunopharmacological interventions aimed on specific prophylaxis and therapy of diseases caused by CNT. A considerable amount of experimental data obtained in vivo on inhalation animal models allows to establish the hygienic standardfor CNT in the air of the working area. As to safe levels of the oral route of CNT it needs further study for their reliable assessment. The search and selection of sources for the review was executed with the use of public databases, including (in order of relevance) PubMed, Scopus, Google Scholar, and RISC, for the period from 2004 to 2017.

Résumé :
The contribution deals with leaf area assesment of 9 grapevine varieties. The measurements were carried out by means of Leaf Area Metr CI-202 (scanner type). The results show, that the size of leaf area per vine is as foolow: 1,16–2,09 m2 during the prolongation growth stage, 1,49–3,20 m2 during flowering and 1,99–3,30 m2 during bunch and cane ripening. The quickest growth of leaf area is during phenological stage of flowering. The varieties Hibernal, Müller Thurgau, Sauvignon blanc, Saint Laurent, Zweigeltrebe have adequate proportion of leaf area and carry-over. On the contrary the varieties Ranfol bianco, Petit Riesling, André, Limberger have smaller leaf area. The results show option of applied working operations (defoliation, bunch thinning) at veraison.

Résumé :
Microscopical investigation was carried out on leaves of Maytenus emarginata (Willd.) Ding Hou belongs to family celastraceae, is an evergreen tree that tolerates various types of stresses of the desert, locally known as “Kankero” in Hindi, “Thorny staff tree” in English. Literature survey revealed that not much work has been done on this plant, especially on leaves. So we have taken its detailed microscopical studies to prove its appropriate identification. Microscopical study provide information that the lamina is dorsiventaral and 380µm thick. The Lamina is amphistomatic, the stomata being distributed both on the adaxial and abaxial sides. Calcium oxalate crystals of druses are fairly abundant in the mesophyll tissue. The stomata are cyclocytic type. The venation is densely reticulate. The terminations are either simple or more commonly forked into deuse clusters. Powder Microscopy show that the sclereids are fiber like in shape and size. The sclereids are 500 µm long and 30 µm thick. Long or short, cylindrical mesophyll cells are common with powder. They have dense tannin contents. The cells have thin wall and the cells are up to 200 µm long and 60 µm wide. Calciumoxlate druses are quite abundant in the power. They are spherical bodies with spiny surface. The druses are 30 µm in diameters. The above studies provide useful information in regard to its correct identity, evaluation and help to differentiate from the closely related other species of Maytenus Emarginata (Willd.)Ding Hou.

Résumé :
Modification of date palm leaf and leaf-end pruning machine was carried out according to the following aspects: Considering the conventional pruning method, Geometric dimension of the usual garden tool (sickle) or local named Acfea, Morphological form of date palm tree, Designed machine dimension.In this study, the main aims were focused on: Agronomical specifications, - machine net weight, - on farm operation, - application efficiency. To design and develop this machine, a lightweight Hydro-motor as well as proper size frame, handle, proper, hydraulic control valve and a disk-type cutting blade were used. The machine is able to pruning the leaves and leaves-end with depth of up to 10 cm. In general, two changes were considered for on farm application: as a part of date palm service machine and /or a self-operating machine.In the first phase, because of the lack of enough space for bucket of machine to reach the date palm trunk, pruning operation can be perform from a distance from 1 to 2 meter from the main tree trunk; therefore, the designed machine was equipped with a 3-meter length boom so it can be controlled from the lifting cabin. In the second phase, for the trees that are not higher than 4 meters, the machine can be used as a self-operating machine by ladder.The machine was equipped with a short and convenient handle, which will help the pruner to reach the tree trunk for pruning the leaves and leaves’ end.The prototype pruning machine was installed to the tractor MF-285 and site conditions to test and evaluate performs the machine technical and ergonomically parameters was successful. Field operation of tractor mounted leaf and leaf-end pruning machine was performed in Date Palm and Tropical Fruits Research Institute. 95% of the confidence interval of pruning leaf and leaf-end were achieved between 8 to 14 s and 10 to 19 s, respectively. The total pruning time was gained between 9.9 to 13.8 min for each tree.

Résumé :
AbstractA leaf choice experiment was conducted and the behaviour of the female weevil was observed before she commenced cutting. The female always performed a sequence of stereotype behaviours preceding cutting. The results of this study indicate that the female firstly decides the number of eggs to be laid in the cradle and then starts looking for a leaf suitable for that number of eggs. While the female is making a cradle, she measures and perceives for different purposes three different distances on the leaf (or something that represents each of them: 1) the length of the whole leaf, i.e. the criterion of adequacy of a leaf for a cradle, 2) the leaf width, i.e. the criterion of adequacy of a leaf for a two-egg cradle, and 3) about 1 cm along the main vein from the leaf base, i. e. the determinant of the cutting site. These three are probably measured while the female is performing the stereotype walking. Measuring both leaf length and leaf width amounts to predicting the shape and the size of the cradle.

Résumé :
Abstract. The study was conducted on “Khoderi” olive cultivar planted in Jableh Region-Latakia province, Syria in 2017 in order to evaluate some mathematical models adapted for olive single leaf area estimation. Leaf samples were taken from the middle of one-year branches. Actual areas of the leaves were measured using Adobe Photoshop CS5. Leaf dimensions (length and width) were measured accurately. Coefficients of determination were estimated for the relation between leaf dimensions and the actual area. The best coefficient of determination was between the natural logarithm of the product (leaf length × leaf width) and the natural logarithm of leaf area (R2= 0.962). Linear regression equation of the mentioned relation was fitted and evaluated. The accuracy of the new model (A=e0.9509ln LW – 0.2867) was compared to other models commonly used for olive single leaf area estimation. The comparison showed no significant differences between leaf area obtained by the new model and the actual leaf area values (p=0.01), whereas significant differences were found for the other models. The new model showed the lowest Root Mean Square Error (RMSE) and high efficiency in estimating olive leaf area of “Khoderi” cultivar in two different environments; the same results were obtained for olive cultivar “Picholine” the French. We recommend the new model for olive single leaf area estimation.

Résumé :
Selected physiological and anatomical characteristics of four chilling-tolerant sweetpotato genotypes were evaluated. Although the genotypes were considered highly tolerant to chilling, it was proposed that differences in their mechanism for tolerance existed. A genotype temperature interaction for chlorophyll fluorescence ratio was observed when the plants were exposed to 5 °C. Genotype differences were found for electrolyte leakage and peroxidase activity. There were no differences found for fatty acid percentage composition of the glycolipid or the phospholipid fraction from leaf samples. There were no differences in diffusive resistance and transpiration rate among the genotypes; however, stomata density, leaf shrinkage, and specific leaf weight differed among the genotypes. Differences were also found among the genotypes for percent leaf dry weight, leaf thickness, and cellular structure of the leaf. It was concluded that the basis or mechanism for chilling tolerance was not the same for the four genotypes tested; therefore, combining traits for tolerance could lead to higher tolerance levels.

Résumé :
Physiological parameters of drought tolerance of fi ve raspberry varieties (‘Meteor’, ‘Gusar’, ‘Lavina’, ‘Patricija’, and ‘Ulyabka’) and seven selected raspberry forms (4-122-2, 6-125-3, 1-76-1, 6-125-4, 2-83-21, 1-76-25, 2-90-3) were investigated. Experiments were conducted in 2022–2023 at the Kokinsky experimental station of the Federal Horticultural Center for Breeding, Agrotechnology and Nursery (Bryansk Oblast) and at the Center for Collective Use of Bryansk State Agrarian University. Drought tolerance was assessed based on the indices of total leaf water content, water defi cit, and water-retaining capacity in the phenophases of budding (May) and fruiting (July). The analysis showed that within one vegetation period, the total leaf water content and water-retaining capacity decreased from the phase of budding to that of fruiting, compared to water defi cit, which showed an inverse trend. The water-retaining capacity of the studied varieties was found to be higher in a drier season than in a moderatelyhumid year. A signifi cant variability among genotypes was observed in terms of water regime. During the fruiting phase, the total leaf water content decreased to an average level in all the studied genotypes (less than 70.0 %), except for the ‘Gusar’ and ‘Lavina’ varieties which demonstrated lower levels (less than 60.0 %). Forms outperforming in a number of leaf water regime parameters were identifi ed. Thus, the ‘Meteor’ variety, although showing high values of water content in the budding phenophase, was characterized by low water losses after 6-hour wilting (less than 30.0 %) and a leaf water defi cit (less than 10.0 %). Water defi cit in the ‘Ulyabka’ variety, as well as 6-125-4 and 2-90-3 selected forms, exceeded 10.0 % in the fruiting phenophase, corresponding to the average level of drought tolerance. The 2-83-21 form showed a reduced water-retaining capacity in the fruiting phenophase (water losses exceeded 30.0 %).

Résumé :
Lilies (Lilium spp.) are famous bulb flowers worldwide, with high ornamental value. Aphid damage has seriously constrained the development of the lily industry. In this study, the aphid resistance of 16 lily cultivars and 2 wild lily species was characterized in the field and greenhouse. Leaf color parameters, stomatal density and size, thickness of leaf layers, leaf waxy content, and leaf water content were determined to explore the constitutive resistance of lilies. The results show that there was a significant positive correlation between the number of aphids in the field and in the greenhouse (p ≤ 0.05, r = 0.47). This indicated that the level of aphid infestation in both the field and the greenhouse is generally consistent across different types of lily plants. Among these 18 lilies, ‘Palazzo’, ‘Nymph’, ‘Cameleon’ and L. lancifolium were resistant to A. gossypii, while ‘Black Beauty’ and ‘Magnefique’ had poor resistance. The correlation analysis results showed that the number of aphids was negatively correlated with leaf abaxial surface a*, stomatal size, water content, and thickness of leaf palisade tissue and positively correlated with leaf distal axial surface b*, C*, and waxy content. Among them, the correlation between the number of aphids and the thickness of leaf palisade tissue reached a significant level (p ≤ 0.05, r = −0.521). This indicated that the thickness of the palisade tissue of lily leaves might be an important factor influencing the proliferation of aphids. This study not only screened out aphid-resistant lilies but also established a crucial research foundation for the targeted breeding and molecular breeding of lilies with aphid resistance.

Evaluation of forty mulberry accessions for morphological, growth and yield parameters was carried out during the year 2021-2022 at the Department of Sericulture, Forest College and Research Institute, Mettupalayam.Qualitative traits such as growth nature, leaf surface, leaf lobation, leaf color and leaf wrinkles showed distinct variations in the present study. Among the forty accessions, the highest number of shoots/ plant was recorded in MI-0845 (27.40) and the highest shoot length was recorded in ME-0247 (230.70cm).The highest Internodal length was recorded in MI-0715 (8.39cm), the maximum number of leaves per plant was recorded in MI- 0145 (584.00) and the maximum leaf area was recorded in MI-0477 (321.51cm 2 ). Specific leaf area was maximum in MI-0615 (282.50 cm 2 /g) and a maximum number of leaves per branch were recorded in MI-0817 (55.80). The maximum 100 leaf weight was recorded in MI-0828 (673.40g) and leaf dry weight was significantly high in MI-0477 (88.71 g/plant). Phenotypic correlation between a number of shoots per plant showed a significantly positive correlation with specific leaf area and number of leaves per plant. Shoot length exhibited a significantly positive correlation with internodal length, number of leaves per plant had significantly positive correlation with specific leaf area. A significant and positive correlation between growth and yield traits can be utilized for mulberry leaf yield improvement. Based on the cluster analysis, 40 mulberry accessions were grouped into seven clusters. Among the clusters, cluster I and V exhibited maximum variability. The variability existing in the forty mulberry accessions provides opportunities for breeders to select specific donors for genetic improvement.

Résumé :
<p>The study was carried out to evaluate the hepatoprotective activity of leaf and leaf callus extracts of <em>Anisochilus carnosus</em> (L) Wall. against alcohol induced toxicity using HepG2 cell line. Leaf explants were cultured on Murashige and Skoog solid medium supplemented with different growth regulators. Prior to the determination of hepatoprotective property leaf and leaf callus extracts were subjected to the toxic dose study. The degree of hepatoprotection of extracts was determined by measuring cell viability percentage by MTT assay. The preliminary phytochemical analysis of leaf and leaf callus was carried out by qualitative analysis. Maximum percentage of callus formation (98%) was obtained in MS medium fortified with 3 mg/l 2,4-D. HepG2 cells were pretreated with the different concentrations (below toxic dose) of leaf and leaf callus extracts for 72 hours followed by alcohol intoxication. Results revealed that ethanolic leaf extract pretreated HepG2 cells show 94% cell viability compared to the standard silymarin pretreated HepG2 cells which showed 81% cell viability. Leaf callus extracts also exhibited significant hepatoprotective activity where ethanolic callus extract pretreated HepG2 cells showed 86% viability after intoxication with alcohol. Results revealed that HepG2 cell viability percentage is dose dependent. Phytochemical studies revealed the presence of different secondary metabolites in leaf and leaf callus extracts. The bio-efficacy study confirms the presence of secondary metabolites of hepatoprotective nature in leaf and leaf callus of <em>A. carnosus.</em></p>

Résumé :
Fertilizer rates of N, P, K were evaluated over 4 years (2000–03) as were different sources of experimental and commercial fertilizers. The highest total yields and yields of jumbos (≥7.6 cm) occurred with nitrogen rates of 140–168 kg·ha–1. Neither phosphorus nor potassium rates had an affect on total yield. Phosphorus rates of 0-147 kg·ha–1 and potassium rates of 0–177 kg·ha–1 were evaluated. Increasing nitrogen fertilizer resulted in increasing leaf tissue nitrogen, but did not affect P, K, Ca, or S. Increasing phosphorus fertilizer increased leaf tissue phosphorus only slightly (p = 0.060) with no affect on other leaf nutrient levels. Increasing potassium fertilizer did affect leaf tissue potassium 2 out of 4 years with none of the other leaf nutrient levels affected. Several fertilizers were also evaluated including an experimental fortified peat (10%N), calcium nitrate, ammonium nitrate, diammonium phosphate, 5–10–15 (56 kg·ha–1 N), 18-6-8 liquid, 14–0–12 8%S liquid, 19–8–19 slow-release at rates of 140 and 168 kg·ha–1 nitrogen. All were used to supply 168 kg·ha–1 nitrogen unless noted otherwise. P and K were supplied according to soil test recommendations unless they were part of the fertilizer formulation. There were no differences between the different fertilizer sources for total yield and differences in jumbo yields only occurred one year out of three years of testing and for medium (≥5.1 and <7.6 cm) yields there were differences two years out of three years of testing.

Résumé :
A significant proportion of the aboveground green and dry weight of the plant constitutes the foliage. The canopy is an important factorof plant growth. On one hand the canopy absorbs the solar energy, which is necessary for the photosynthesis, on the other hand accumulatesthe absorbed nutrients by the roots, and the most of the water-loss happens through the foliages. The determination of the full canopy is notan easy target. In our research we developed a measurement method to determine the leaf area. With the parameters of the examined tree(leaf length and maximum width) and the data of ADC AM 100 leaf area scanner we determined the k-value, with which we can easily andfast evaluate the leaf surface. Furthermore we defined from the water balance of compensation lysimeters the cumulative transpiration offruit trees and the efficiency of water use of trees.

Résumé :
Established open pollinated seedling seed orchard of Grewia optiva Drummond (60 families) established at main campus of Dr. Y.S. Parmar University of Horticulture and Forestry, Solan during July 2000 was evaluated for various morphometric parameters as per standard methodology, viz., height, diameter, current years’ leaf production, leaf area, fresh leaf weight, leaf dry weight, total fresh leaf biomass and leaf dry matter contents. Growth parameters among the different genotypes showed a wide range of variation. The means of the morphometric parameters of different families of Grewia optiva recorded a maximum mean height (6.75 m), diameter (8.88 cm), leaf dry matter content (59.40%), estimated number of leaves (2230.30) fresh weight of leaves (81.33 g/100 leaves), dry weight of leaves (44.56 g/100 leaves), leaf area (68.10 cm2) and total green biomass (1760.74 g). Studies concluded that differences are due to genetic factors. The identified families on the basis of morphometric traits can be used for long term breeding programmes to achieve significant gains from diverse populations.

Résumé :
Variation among different traits along with their correlation were studied in twenty seven clones of Morus alba . The significant differences were found among clones with respect to various morphometric traits. Moderate phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), heritability and genetic gain were recorded for green leaf yield, ramet height, leaf length, leaf width and basal diameter indicating that these characters can be more reliable for effective selection in future. Ramet height showed positive and significant correlation with basal diameter (0.5287), leaf length (0.4671), number of branches (0.6043), and green leaf yield (0.6893). Basal diameter, leaf length and leaf width also exhibited positive and significant correlation with green leaf yield i.e. 0.4705, 0.5714, 0.4813, respectively. Hence, these correlations can be useful in the indirect selection of the species.

Résumé :
Planning agents often lack the computational resources needed to build full planning trees for their environments. Agent designers commonly overcome this finite-horizon approximation by applying an evaluation function at the leaf-states of the planning tree. Recent work has proposed an alternative approach for overcoming computational constraints on agent design: modify the reward function. In this work, we compare this reward design approach to the common leaf-evaluation heuristic approach for improving planning agents. We show that in many agents, the reward design approach strictly subsumes the leaf-evaluation approach, i.e., there exists a reward function for every leaf-evaluation heuristic that leads to equivalent behavior, but the converse is not true. We demonstrate that this generality leads to improved performance when an agent makes approximations in addition to the finite-horizon approximation. As part of our contribution, we extend PGRD, an online reward design algorithm, to develop reward design algorithms for Sparse Sampling and UCT, two algorithms capable of planning in large state spaces.

Résumé :
The aim of this work was to evaluate the nutritional and hepatotoxic potential of leaf of T. danielli. Freshly harvested leaves of T. danielli was dried at room temperature, ground to fine powder. 500 g of powdered plant sample was soaked in 2 litres of 70% methanol for 72 hrs. The resulting extract was filtered and filtrate concentrated. Twenty adult male albino rats were divided into 4 groups of 5 rats per group. · Group I: Normal control was fed with only normal rat diet and water ad libitum. · Group II: Rats were administered with 200 mg/kg b.w of extract of T.danielli leaf orally. · Group III: Rats were administered with 400 mg/kg b.w of methanol extract of T.danielli leaf orally. · Group IV: Rats were administered with 600 mg/kg b.w of methanol extract of T.danielli leaf orally. Nutrient composition of the leaf of T. danielli was determined using standard procedures. The proximate analysis on the leaf of the said plant revealed the presence of moisture, ash, fat, protein, fibre and carbohydrate with fat being more abundant (17.30±1.28%) than every other components and carbohydrate the least abundant (8.29±0.20%). However, analysis on the mineral composition, revealed the presence of calcium, phosphorus, potassium, zinc, sodium and iron. While calcium (7.20±0.23 g/ 100 g) was reportedly the most abundant of all elements, sodium was the least (0.40±0.03 g/ 100g). Evaluation of the vitamin composition of the leaf of T. danielli revealed the presence of vitamins A, B1, B3, B5, B6 and B12. B12 was the most abundant (8.32±0.42 g/ 100g) of the vitamins. The activity of serum hepatomarkers evaluated was not significantly (P>0.05) different from that reported on the control following oral administration of aqueous extract of T. danielli. In conclusion, the leaf of T. danielli contains vital nutrients and has no hepatotoxic effect.
