It is investigated the effect of synthesized organic compounds of 6-hydroxy-2,2,4-trimethyl-1,2- dihydroquinoline, its derivatives, and hydrogenated analogs. These compounds affected the height of seedlings when they were used for pre-sowing seed treatment of the following ornamental plants: annual ornamental grass – scarlet sage (Salvia splendens) and woody plant – yellow rhododendron (Rhododendron luteum). Prior to the sprouting process, the seeds of Rh. luteum and S. splendens were soaked in water solutions of compounds with concentrations of 0.01%, 0.05%, and 0.1% for 18 hours. Dihydro- and tetrahydroquinolines with a concentration of 0.05% proved to be the most effective for both plants. For Rhododendron luteum, the compounds of 6-hydroxy-2,2,4-trimethyl-1,2-dihydroquinoline, its derivatives, and hydrogenated analogs with a concentration of 0.1% proved to be the most effective. Dihydroquinolines at concentrations of 0.05 and 0.1% proved to have the strongest effect when applied to the studied perennial woody plant (Rhododendron luteum). Dihydroquinoline at the concentration of 0.05% also proved to be effective when applied to the annual grass (Salvia splendens). For annual S. splendens, tetrahydroquinoline at concentrations of 0.01 and 0.05% appeared to be the most effective. The pre-sowing seed treatment of grass Salvia splendens and woody plant Rhododendron luteum with the studied compounds demonstrated that their effect on the height of the seedlings is species-specific. The pre-sowing seed treatment of Rh. luteum and S. splendens allows increasing the height of the seedlings by 3-61 % and 17-25 %, respectively. It is suggested using the compounds of 6-hydroxy-2,2,4- trimethyl-1,2-dihydroquinoline, its derivatives, and hydrogenated analogs as effective growth stimulators for ornamental grasses and woody plants.

The effects of stubble management treatments on take-all (Gaeumannomyces graminis var. tritici) of wheat were examined in 2 field experiments in north-eastern Victoria. Wheat stubble from a preceding crop was left standing, mulched, burnt or incorporated into soil prior to sowing wheat. At Rutherglen in 1984, neither the incidence nor the severity of take-all was affected by these treatments. Although the severity of root symptoms on take-all affected plants at anthesis and the incidence of white heads were very low, sowing with a zero till, triple disc drill resulted in a small but significant (P<0.05) increase in both disease severity and white head incidence (2% tillers with white heads), compared with sowing with a conventional tine drill (0.6% tillers with white heads), regardless of the stubble treatment. At Wilby in 1985, the incidence and severity of take-all in wheat at early tillering was higher in plots in which wheat stubble was incorporated into soil prior to sowing (16% plants affected), than in plots where stubble was left standing, mulched or burnt (2, 3 and 4% plants affected, respectively). At anthesis, however, there were no significant differences in the incidence of affected plants between the 4 stubble treatments (average of 81 % plants affected).

The threat which is on the forests and wooded spaces of Africa and particularly those of Côte d'Ivoire is accentuated over the years. The quoted leading causes are the land pressure related to demography, the anarchistic exploitation of the forest woody plants and itinerant agriculture. In many cases, the afforestation is the recommended palliative measure. But with which woody plants does one retimber in Côte d'Ivoire? Which assessment are previous initiatives made? On several occasions the exotic woody plants with rapid growth were used without success. The main objective of this study is to identify local woody plants with rapid growths of which the use will contribute to a significant degree to fast regeneration of our forests, degraded spaces and the post-farming fallow. Floristic inventories and measurements were carried out on the stems of Albizia adianthifolia and Albizia zygia in elementary plots of 400 m ² (20m X 20m). Two local arborescent Leguminous plants with rapid growth were identified for this purpose. They were: Albizia adianthifolia and Albizia zygia. The experiments showed that these species reach the maximas of their growth in height and thickness as from nine (9) years. The sowing of the fallow and/or spaces degraded by these woody species supports the fast regeneration of these degraded spaces.

The effect of synthesized organic compounds of 6-hydroxy-2,2,4-trimethyl-1,2-dihydroquinoline, its derivatives, and hydrogenated analogs on the height of seedlings of ornamental woody plants was studied. The height of seedlings as a morphometric parameter was measured 7 months after the start of the experiment. The pre-sowing seed treatment of Rhododendron ledebourii and Rhododendron smirnowii, with the studied compounds, demonstrated that dihydro- and tetrahydroquinoline with the concentration of 0.1% proved to be the most efficient. Dihydroquinolines at concentrations of 0.05 and 0.1% proved to have the strongest effect. Dihydroquinolines for perennial woody plants are more effective, then tetrahydroquinolines. The most efficient synthesized chemical compounds for Rhododendron contain benzoyl substitute. For Rh. ledebourii and Rh. smirnowii the most effective are the same synthesized chemical compounds: 6-hydroxy-2,2,4-trimethyl-1,2,3,4-tetrahydroquinoline, 6-hydroxy-2,2,4-trimethyl-1,2-dihydroquinoline, and 1-benzoyl-6-hydroxy-2,2,4-trimethyl-1,2- dihydroquinoline with concentrations of 0.01, 0.05, and 0.1%. These compounds, when applied with the presowing seed treatment of Rh. ledebourii and Rh. smirnowii, result in an increase in the height of the seedlings by 3.6-89.3% and 14.3-57.1%, respectively. The effect of synthesized chemical compounds of 6-hydroxy-2,2,4-trimethyl-1,2-dihydroquinoline and its hydrogenated analog on woody plants of the same genus is not speciesspecific. It is suggested using the compounds of 6-hydroxy-2,2,4-trimethyl-1,2-dihydroquinoline, its derivatives, and hydrogenated analogs as growth stimulators for Rhododendron. The compounds of the quinoline series were tested for genotoxicity by the cytological method in the model object (Betula pendula) and recognized as environmentally friendly. The cytogenetic responses for Betula pendula and Rhododendron are identical, so positive compounds influence for Betula pendula cells because of increased metabolic activity means the same for Rhododendron. Therefore, synthesized organic compounds can be recommended as effective growth stimulators.

The article analyzes the degree of introduction of phanerophytes, which form the cultural dendroflora of the northeastern part of the Greater Caucasus (Azerbaijan). The research showed that out of 115 species studied, 11 were naturalized (CH1), 71 species had good viability (CH2), 25 species had medium viability (CH3), 8 species had poor viability (CH4), resistant species (CH5 group) were not found. As a result of the research, it was concluded that woody plants that form the cultural dendroflora of the study area had a different degree of introduction in accordance with environmental requirements. The results of the study showed that for the successful introduction of the studied woody plants, planting and sowing must be carried out from different geographically productive individuals with different geno- and phenotypic characteristics in the natural habitat, taking into account the bioecological characteristics of the species and their historical past, i. e. phylogenesis. It is more expedient to collect and mobilize material.

The effect of different cultivation and sowing methods on wild radish (Raphanus raphanistrum L.) density in 4 successive wheat crops was measured in an experiment in north-eastern Victoria. The number of seasons taken for populations to decline below an estimated threshold for economic spraying of wild radish (5-10 plants/m2) was examined. Two herbicide applications in each crop in all but one treatment prevented or significantly reduced wild radish seed production during the experiment. Wheat sown after mouldboard ploughing (MBP) in the first season contained wild radish at 42 plants/m2, before spraying. Densities were significantly higher (P<0.05) when wheat was direct drilled (96 plants/m2), or sown after cultivation to 80 mm (116 plants/m2) or to 50 mm (202 plants/m2). MBP in the first season followed by cultivation to 80 mm or direct drilling in subsequent seasons resulted in wild radish populations below the threshold for economic spraying in the second crop. Cultivation to 80 mm before sowing in the first 2 years, followed by direct drilling in subsequent years resulted in a wild radish population of 6.9 plants/m2 in the third crop. This density was within the range estimated as the threshold for economic spraying. Wild radish densities on treatments cultivated to 50 or 80 mm before sowing, or direct drilled each year, had declined to within or below the threshold for economic spraying by the fourth crop.

Abstract The created collections of woody plants made it possible to evaluate the life cycle of forsythia Forsythia ovata Nakai, privet Ligustrum vulgare L., and high ash Fraxinus excelsior L. of the Oleaceae Hoff family. et Link. and their response to changing climatic conditions. Tall ash, common privet froze every year to the level of snow cover. The flower buds of the forsythia froze, and it did not bloom. Due to the increase in the average annual temperature from 1.7 °C to 2.69 °C since 1990, forsythia and privet began to bloom and bear fruit. Introductory populations were created and the most frost-resistant and abundantly flowering individuals were selected. But as a result of abnormal weather conditions and climate cyclicality, all young and old privet plants died in 1998. Common privet plants began to bloom profusely only in 2021 (sowing in 2018). High ash plants fully recovered and reached a height of 10-12 m.

In some areas the increase of woody plants is a problem whereas in others, the lack of regeneration is viewed with a similar degree of concern. The experiments described in this paper were an attempt to further understand factors affecting regeneration of woody plants. The effect of seedbed on the emergence and survival of hopbush (Dodonaea viscosa ssp. angustissima) and on several species of Eucalyptus was evaluated at two sites in the Central West of New South Wales. Seed was sown in two springs, two summers and two autumns from 1990 to 1992 and seedlings monitored for 12 months after sowing. Seedbeds compared were prepared by cultivation, scalping, burning, applying herbicide (glyphosate) and mowinglgrazing (control). Following failure of surface sowing in spring 1990 and summer 1990191 due to poor seasonal conditions, all subsequent experiments included direct drilled controls. Emergents were recorded in most treatments in the four succeeding seasons but hopbush and eucalypts responded differently to treatments. Numbers of hopbush emergents and seedlings after 12 months were consistently higher following direct drilling into scalped seedbeds. In contrast, the maximum number of eucalypt emergents was not consistently associated with any seedbed type, though emergence was generally higher following direct drilling. However, higher numbers of eucalypt seedlings were present in scalped plots after 12 months. It was concluded that weed control following emergence was the main effect of seedbed preparation on the number of eucalypt seedlings present after 12 months. Though this also applied to hopbush. seedbeds which provided the opportunity of seed burial enhanced emergence. This was believed to be due to the breaking of seed dormancy.

Field experiments were established at Horsham, in the Wimmera region ofVictoria, in 1987, 1988 and 1989 to compare the severity of ascochyta blightand grain yield of field peas sown in May, June and July. In each year, theseverity of ascochyta blight on all the pea cultivars studied was greatest onthe May-sown plots and least severe on the July-sown plots. The level of seedinfestation by ascochyta blight fungi was also highest in grain harvested fromthe plots sown earliest. In 1987, the average length of lesions girdling themain stem was 28.7 cm in the May-sown plots and 1.0 cm in the July-sown plots.In 1988, the average percentage of stem area affected by ascochyta ranged from 60.2% in the May-sown plots to 13.1% in the July-sown plots,while in 1989 the range was from 38.3% in the May-sown plots to5.8% in the July-sown plots. In 1988, delaying sowing until Julyresulted in a significant reduction in disease with only a small reduction inyield. However, in 1989 while July sowing reduced the severity of disease by 17%, compared to a June sowing, the later sowing also reduced grainyields by 40%.In a separate trial at Horsham in 1988, using cv. Buckley, disease progresswas most rapid on the April-sown plots and slowest on the August-sown plots.The final disease levels ranged from 100% of stem area affected (Aprilsowing) to 2% of stem area affected (August sowing). The yield lossescaused by the disease were greater the earlier the plots were sown.These studies suggest that the severity of disease in commercial crops may bereduced by delaying sowing until after mid-June, thus avoiding exposure ofyoung plants to high levels of primary inoculum.
