Euphorbiaceae is the most diverse angiosperm plant with one of the largest number of species widely used in various industries. Exploration and inventory of the Euphorbiaceae family has not been maximized, including in Salatiga City. Its great potential requires an initial step, namely plant breeding, but knowledge of its phenetic relationships is needed so that plant breeding produces superior individuals. In addition to morphological characters, chemical properties such as milk clotting activity are important in understanding the phenetic relationships. This study aims to analyze the phenetic relationships of Euphorbiaceae members in Salatiga City based on their morphological and chemical characteristics as well as from the milk clotting activity. Twenty five individual members of the Euphorbiaceae were analyzed for their morphological and chemical characteristics, and 30 characters were obtained. The results of the study using Cluster Analysis method showed that 25 individuals formed cluster A which was divided into 2 parts (clusters C and D) and cluster B formed cluster G (consists of individuals of Codiaeum variegatum (L.) Bl.). The closest phenetic relationships between Jatropha multifida Sidomukti C09 and Jatropha multifida Sidorejo C18 with a dissimilarity index of 0.03% or the equation 99.97%. The most distant phenetic relationships in Codiaeum variegatum (L.) Bl. Sidorejo C11 and Codiaeum variegatum (L.) Bl. Sidomukti C03 with a dissimilarity index of 19.13% or the equivalent percentage of 80.87%. The genus Euphorbia formed cluster F. The genus Manihot and Jatropha formed cluster C, the genus Codiaeum formed clusters E and B. All individuals, except Codiaeum variegatum (L.) Bl. Sidorejo C11, can coagulate milk so that it has potential as a protease enzyme in various industries. The highest protease enzyme activity value was in Codiaeum variegatum (L.) Bl. Sidorejo C11 (15.84 U/mg) and the lowest was in Euphorbia tirucalli Sidomukti C07 (2.34 U/mg).

Annotation:

Stomata, which are specialized cells on the surface of leaves, undergo modification to form structures containing two guard cells. These cells play a crucial role in facilitating the exchange of water vapor and gases between the plant's internal environment and the surrounding atmosphere. Typically located on plant parts exposed to air, such as leaves, stems, and rhizomes, stomata distribution varies among different species. While some plants exhibit stomata on both upper and lower leaf surfaces, others, like water lilies, exclusively feature stomata on the upper side.The objective of the current investigation was to analyze the stomatal anatomy of various plant species within the Euphorbiaceae family. Employing a qualitative descriptive approach, the study aimed to characterize and interpret the stomatal types present on the leaves of Euphorbiaceae plants in the Langsa City region. The findings revealed the presence of five Euphorbiaceae species in Langsa City, including Euphorbia mili (jade fern), Jatropha curcas (Jatropha curcas), Codiaeum variegatum 'Norma' (norma puring), Codiaeum variegatum Bi (jet puring), and Codiaeum finger (finger puring), all of which exhibited parasitic stomatal types.

This study aimed to obtain a Puring cultivar (Codiaeum variegatum) that can adapt to heavy and robust copper (Cu) stress and test its potential as a phytoremediation plant. The method used was a randomized block design (RAK). The results showed that the number of leaves and plant height did not show a significant difference. The most important copper (Cu) convergence in the formation was found in the Teri cultivar, with a convergence level of 126,399 ppm. In conclusion, puring cultivar can be used as a phytoremediation agent in an environment contaminated with substantial copper (Cu) metal because of its long roots and does not require more expensive costs. Keywords: Puring Cultivars (Codiaeum variegatum), Copper Metal Cu, Phytoremediation

Annotation:

Indoor landscaping is an environmentally friendly approach that enriches the environment and fosters productivity and comfort for occupants. The practice of incorporating plants into interior spaces requires meticulous care to ensure healthy growth and prolong the benefits of interior greening. This study explores the impact of natural and artificial light, represented by fluorescent lighting on the growth and physiological responses of Codiaeum variegatum and Ardisia japonica. A natural light chamber and an artificial light chamber of identical dimensions were constructed to compare the plants’ physiological responses under consistent temperature, humidity, and illuminance conditions. The results indicate that Codiaeum variegatum and Ardisia japonica exhibited higher chlorophyll content and photosynthetic rates under natural light conditions compared to fluorescent lighting. Furthermore, the study found that natural light offers a rich spectral distribution across various wavelengths, providing an advantage for plant growth. Although direct comparisons between natural and artificial light environments are inherently challenging due to the distinct characteristics of each light source, the study emphasizes the importance of considering the rich spectral distribution of natural light when designing artificial lighting systems for optimal plant growth. In conclusion, understanding the effects of natural and artificial light on indoor plants is crucial to supporting plant growth and creating more effective indoor gardening solutions. Although direct comparisons between natural and artificial light environments are inherently challenging due to the distinct characteristics of each light source, natural light provides a more advantageous environment for growth compared to fluorescent lighting, with Codiaeum variegatum and Ardisia japonica both exhibiting a higher chlorophyll content and photosynthetic rate under natural light conditions.

Annotation:

Codiaeum variegatum (L.) Blume is one of the most popular ornamental foliage plants. It encompasses more than 300 recognized cultivars valued by their wide range of leaf shapes and vivid foliage colors. Thus far, only limited information is available regarding the genetic basis of their leaf morphological variation. This study investigated the chromosome numbers and karyotypes of seven phenotypically diverse cultivars. Root-tip cells were fixed, mounted, and observed under light microscopy. Results showed that chromosome numbers in the mitotic metaphase of the seven cultivars were high and variable and ranged from 2n = 66, 70, 72, 76, 80, 82, 84, to 2n = 96, indicating that the cultivars are polyploid and some could be aneuploid. Genetic mosaics occurred in one of the seven cultivars. Additionally, each cultivar had its own karyotype. There were no relationships between chromosome numbers or karyotypes and leaf morphology. Results from this study suggest that the morphological diversity among cultivars of this species could be in part attributed to high variation in chromosome numbers and karyotypes.

Abstract Viterra hydrogel at rates of 0, 1.75, or 2.50 kg·m−3 was tested for the production of three tropical ornamental plant species in two or all of the three media. These were a commercial peat-lite medium (SUN), a medium consisting of equal volumes of peatmoss, bark, and sand (PBS), and a mix containing equal volumes of peatmoss and bark (PB). Codiaeum was grown in SUN and PBS, Dieffenbachia was produced in all three media, and Hibiscus was planted in SUN and PB. Codiaeum variegatum (L.) Blume ‘Norma’ and Dieffenbachia ‘Camille’ grew more and required a longer time to reach initial wilting when grown in SUN than PBS. Hibiscus rosa-sinensis L. ‘Brilliant Red’ had similar growth in SUN and PB. In general, hydrogel had no beneficial effect on plant growth in a greenhouse. Hydrogel extended the time required to reach initial wilting of C. variegatum by 3 days (from 24 to 27 days), but had no effect on Dieffenbachia. Leachate from PBS had higher pH and lower electrical conductance (EC) than that from SUN. Hydrogel had no effect on leachate pH, but decreased EC of the leachate for C. variegatum used at the 2.5 kg·m−3 rate and for H. rosa-sinensis at both rates.

Tanaman puring memiliki varietas yang sangat banyak dan terdapat sekitar 260 varietas puring yang ada di Indonesia. Puring merupakan tanaman yang memiliki warna dan bentuk daun yang beragam seperti kuning, hijau, merah dan coklat sehingga tanaman puring dimanfaatkan sebagai tanaman hias warna-warni tersebut disebabkan karena adanya bermacam-macam pigmen warna didalam daun. Dalam proses fotosintesis klorofil atau pigmen hijau daun sangat diperlukan sehingga setiap daun sangat membutuhkan klorofil. Belum ada data yang menunjukkan apakah perbedaan dominansi warna pigmen daun juga mengandung perbedaan kandungan klorofilnya. Penelitian ini dilakukan untuk mengkaji pengaruh perbedaan warna daun pada 9 varietas dan perbedaan umur tanaman terhadap kandungan klorofil tanaman puring (puring cobra, puring spageti lokal, puring bor merah, puring jengkol, puring jempol, puring jet merah, puring kura-kura moncolor, puring bor cristata, puring lele) dan perbedaan umur daun tanaman terhadap kandungan klorofilnya. Hasil penelitian menunjukkan bahwa daun pada umur 3 bulan kandungan klorofilnya sama pada semua varietas baik kandungan konsentrasi klorofil total, klorofil a maupun klorofil b. Pada 3 varietas (puring cobra, puring spageti lokal dan puring bor merah) daun yang telah berumur 8 bulan mengandung konsentrasi klorofil total dan klorofil a yang berbeda antara daun muda dan daun tua sedangkan konsentrasi korofil b tidak berbeda pada semua varietas.Croton plants has so many varieties. Around 260 varieties of Croton plants are found in Indonesia. Croton plant is a plant with various color leaves such as yellow, green, red and brown which make Croton plant is used to be a house-plant. Those colors exist because of many color pigment in leaf. Every leaf needs chlorophyll or green pigment in photosynthesis process. There is no data that shows different color leaves contain different amount of chlorophyll. This research is done in order to find out the effects of difference in color leaves and plants age towards chlorophyll contents in Croton plants (puring cobra, puring spageti lokal, puring bor merah, puring jengkol, puring jempol, puring jet merah, puring kura-kura moncolor, puring bor cristata, puring lele) and different leaves age towards chlorophyll contents. The results showed that the leaf at the age of 3 months has the same chlorophyll contents whether in total chlorophyll, a chlorophyll ad b chlorophyll with the other varieties. The leaf in the age of 8 months in 3 varieties (puring cobra, puring spageti lokal dan puring bor merah) contains different consentration of total chlorophyll and a chlorophyll between young leaves and older leaves while the concentration of b chlorophyll does not differ at all varieties.

Annotation:

A simple and effective method for quantification of leaf variegation was developed. Using a digital camera or a scanner, the image of a variegated leaf was imported into a computer and saved to a file. Total pixels of the entire leaf area and total pixels of each color within the leaf were determined using an Adobe Photoshop graphics editor. Thus, the percentage of each color's total pixel count in relation to the total pixel count of the entire leaf was obtained. Total leaf area was measured through a leaf area meter; the exact area of this color was calculated in reference to the pixel percentage obtained from Photoshop. Using this method, variegated leaves of ‘Mary Ann’ aglaonema (Aglaonema x), ‘Ornate’ calathea (Calathea ornate), ‘Yellow Petra’ codiaeum (Codiaeum variegatum), ‘Florida Beauty’ dracaena (Dracaena surculosa), ‘Camille’ dieffenbachia (Dieffenbachia maculata), and ‘Triostar’ stromanthe (Stromanthe sanguinea) were quantified. After a brief training period, this method was used by five randomly selected individuals to quantify the variegation of the same set of leaves. The results were highly reproducible no matter who performed the quantification. This method, which the authors have chosen to call the quantification of leaf variegation (QLV) method, can be used for monitoring changes in colors and variegation patterns incited by abiotic and biotic stresses as well as quantifying differences in variegation patterns of plants developed in breeding programs.

The floricultural industry is always searching for new and low-cost materials to use as substrate for crop growth and development. Sewage sludge is an organic solid waste from sewage treatment and it has a good potential to be used as an organic fertilizer and/or substrate conditioner. The research aimed to evaluate the rooting and growth of Codiaeum variegatum ‘Andreanum’ (red variety) and Codiaeum variegatum ‘Punctatum’ (yellow variety) cuttings cultivated in the potting media: PM1 - 100% commercial potting media used as control (CS), PM2 - 100% organic compost of sewage sludge + sugarcane bagasse (SSSB), PM3 - 50% CS + 50% SSSB, PM4 - 100% organic compost of sewage sludge + eucalyptus bark (SSEB) and PM5 - 50% CS + 50% SSEB. After 90 days of experimentation the chemical analysis of the substrate solution (pH, electric conductivity, P, K, Ca, Mg, S, Na, B, Cu, Mn and Zn) and number of shoots, shoot fresh and dry mass, plant cutting fresh and dry masses, root fresh and dry masses, total fresh and dry masses and, length of the largest root were analyzed. Our results showed that sewage sludge compost can be used as a substrate for rooting and growth of croton cuttings when mixed with commercial substrate. The use of the pure sewage sludge compound with sugarcane bagasse or eucalyptus bark prejudiced croton cuttings to root.

This objective of this paper was to evaluate the seasonal variations of fourteen (14) ornamental plants as biomonitors of air pollution in three urban areas of Ondo State, Nigeria. The study was carried out in three areas that were purposively selected in Ondo State which are Oduduwa Road, Oloko (traffic congested area), FUTA area (Less traffic congested area) and uncongested area in Elizade University as control. The ornamental plants namely Roystonea regai, Convallaria majalis, Polyalthia longifolia, Ficus benjamina, Dieffebachia amoena, Colocasia esculent, Caesalpinia pulcherrima, Codyline fructicosa, Viburnumt tinus variegatum, Variegatum punctatum, Hibiscus rosa-sinensis, Tradescantia pallida, Codiaeum variegatum, Acalypha wilkesiana were selected purposively and their ascorbic acid contents, pH, relative water contents, total chlorophyll contents and air pollution tolerance index were evaluated using standard methods. The biochemical parameters and APTI values of the ornamentals showed that they have less (APTI<17) tolerance indices during the dry and the wet seasons. Thus, they are more susceptible to air pollutants as biomonitors. At congested areas ornamentals had lesser APTI values at the sampling site than the control site with Tradescantia pallida having the highest (8.86) mean value while Variegatum punctatum had the lowest value of 6.81 during the wet season while Codiaeum variegatum with value 7.08 and the lowest for Variegatum punctatum with value 4.71. Conclusively, this study recommends that in addition with the aesthetic values of the ornamental plants, they can be useful as model bioindicators of air pollution in urban settings.

Codiaeum variegatum (L.) Rumph. ex a. Juss is a common ornamental plant with a high variation of leaves shape and colour. This study aimed to analyze the leaves’ anatomy and the phenetic relationship between eight cultivars of C. variegatum which were defined by the differences in leaf morphology. The paraffin method prepared the transversal section of leaves, and anatomical characters were converted into binary data to calculate the similarity coefficient which was analyzed by Numerical Taxonomy System (NTSYS) 2.1 version. Leaves of eight cultivars of C. variegatum are varied in the anatomical structure of the primary vein and lamina. The eight cultivars of C. variegatum were clustered into four. The variations were found in 19 primary vein and lamina anatomy characteristics and the similarity coefficient is up to 0.59 between all cultivars. It can be concluded that the combination of leaf anatomical structures and midrib anatomical characters have notable taxonomic implications for future research.

The adsorption of metal ion Pb(II) by croton leaf powder through the activation of hydrochloric acid (HCl) or chemical methods has been researched. The research aimed to determine the optimum condition of croton leaf powder as adsorbent by variation of contacting time (30, 60, 90 and 120 minutes) and the difference in mass of adsorbent (1; 2; 3 and 4 grams ). This research began with downsizing the size of croton leafs become to 100 mesh, then was performed chemical activation by soaking the croton leaf powder with 2 N HCl. The adsorption was conducted by contacting the adsorbent with a solution of the sample based on contacting time and mass of adsorbent, then analyzed by Atomic Absorption Spectrophotometer (AAS). The result showed that the optimum condition of adsorption was achieved at 4 grams adsorbent by contacting time in the 60 minutes with Pb(II) adsorbed 1,76 mg/L or 35,2 %. Based on this findings, we concluded that the increase in mass of adsorbent increased the adsorption power of metal ion Pb(II) by optimum contacting time.

The present study was designed to investigate the antidiarrhoeal activity and determine the total tannin content of the ethanolic extract of the leaves of Codiaeum variegatum (Family- Euphorbiaceae). The antidiarrhoeal activity was evaluated in castor oil-induced diarrhoea in mice and the total tannin content was determined by using the Folin-Coicalteu phenol reagent. The ethanolic extract of leaves of C. variegatum showed a positive effect on castor oil induced diarrhoea in mice. In the antidiarrhoeal assay the extract inhibited the mean number of defecation by 40.81% and 59.18% (p<0.01 & p<0.001) at 250 mg/kg and 500 mg/kg body weight, respectively. The latent period for the extract treated group was (p<0.01 & p<0.001) increased as compared to control group. The total tannin content was quite significant and high in ethanolic extract (241.41 mg/g of tannic acid equivalent). Phytochemical screenings of the leaf extract indicated the presence of carbohydrate (reducing sugars), gums, steroids, alkaloids and tannins. Therefore, the results of the present study provide the scientific basis for the traditional uses of this plant as remedy for diarrhea.Dhaka Univ. J. Pharm. Sci. 14(1): 87-90, 2015 (June)

Codiaeum variegatum (L.) Blume, commonly known as crotons, are among the most popular ornamental foliage plants cultivated for either landscaping or interiorscaping. Currently, more than 300 cultivars are available; each has a distinct phenotype, particularly in leaf morphology. Thus far, there is no information regarding their genetic relationships. In this study, genetic relatedness of 44 cultivars of C. variegatum was investigated using amplified fragment length polymorphism (AFLP) markers. Fourteen primer combinations generated a total of 549 AFLP fragments, which were used to estimate genetic distances and construct dendrograms based on the neighbor-joining method. The 44 cultivars were divided into seven clusters, which concurred with the known history of croton geographical isolation, adaptation, introduction, and breeding activities but differed from the classification made by the Croton Society based on leaf morphology. The established genetic relationships could be important for future germplasm identification and conservation and new cultivar development. Additionally, genetic distance among the 44 cultivars was 0.322 or less, indicating that they have a narrow genetic base. The narrow genetic base may indicate that the cultivars were derived from a common progenitor. On the other hand, 81% of the 549 fragments were polymorphic and the average polymorphic information content was 0.22, which suggests that the cultivars are genetically highly polymorphic. The high polymorphisms may be attributed to significant gene loss or gain facilitated by mutation and/or chromosome variation, thus contributing to a wide range of leaf morphological differences among cultivars.

Annotation:

Transpiration rate internally depends on the water content that occupies the tissue in the leaves, which is reflected in the thickness of the leaves. This study measured the transpiration rate and leaf thickness of ornamental dicotyledon plants. The experiment used Factorial Completely Randomized Design (CRD) with three replications. Six species of dicotyledon plants and three parts of the plant were the main factors. The interaction between plant species and plant parts was a combination factor. The transpiration rate was measured using a weighing method and leaf thickness was measured from the upper to the lower epidermis. Leaf thickness was measured before and after transpiration rate measurement. Data were analyzed using SAS with Factorial CRD model and continued with the LSD test if there was a significant treatment. The species of plant and plant parts had significant effects on the transpiration rate and leaf thickness, but the combination or interaction of the two did not affect the transpiration rate and leaf thickness. Aerva sanguinolenta Bi. had the highest transpiration rate followed by Syzygium paniculatum Gaertn., Tabernaemontana divaricata (L.) R. Br. ex Roem. & Schult., Excoecaria cochinchinensis Lour., Bougainvillea glabra Choisy, and Codiaeum variegatum (L.) A. Juss while the leaves at the bottom of the plant had the highest transpiration rate compared to the middle and upper parts of the plant. Codiaeum variegatum (L.) A. Juss. had thick leaves and less transpiration rate than the other plants. The leaves at the top had a higher thickness than those at the middle and bottom parts of the plant. This occurs because the transpiration rate of the lower leaf was faster than the upper and middle parts. Leaf thickness was inversely correlated to the rate of transpiration. Keywords: dicotyledon, leaf thickness, transpiration rate
