The Euphorbia genus is unitary by the presence of the characteristic inflorescence named cyathium, but presents a remarkable morphological diversity of aerial vegetative organs. Species that originated in the tropical zones, especially South-African ones stand out by the presence of some epidermal appendages little known (trichomes, spines, leaf scars). Of those, the spines are the most conspicuous and intriguing from a structural point of view; the botanical terminology used for describing their features is critically presented. The representatives of the Euphorbia genus cultivated in Botanical Garden Iassy greenhouses were morphologically analysed and a detailed description of epidermal appendages resulted, which is useful in clearing taxonomical aspects.

Our recent field research and revision of some herbarium specimens led us to identify two species of Euphorbia (subgenus Chamaesyce), which we report now for the first time in the alien flora of Romania: Euphorbia serpens Kunth and E. glyptosperma Engelm. The first was collected in the city of Iaşi, north-eastern Romania, in September 2018. The second was collected, during 2005-2015, in several localities from the lower basin of the Siret river (Galați County), as well as from north-eastern Romania, near Ciurea (Iaşi County), but previously erroneously identified as “Euphorbia chamaesyce L.”. Both species, originating in the New World, are xenophytes, more or less naturalized in Europe, perhaps in full process of expansion of their secondary area.

The extent of genetic variability among 19 accessions of tomato was studied using genetic variability parameters. Four-week old seedlings were transplanted in a well levelled field with 0.6 x 0.6 spacing and replicated three times in randomized complete block design. High significant differences among the accessions for all attributes studied. Cluster analysis based on 37 agro-morphological attributes separated accessions into two distinct groups according to the fruit types. Values for genotypic and phenotypic coefficients of variation showed variability among the accessions. Correlation analysis showed fruit/plant is positively and significantly correlated to plant height, number of branches/plant and leaf length. Very high genetic advance and heritability estimates for leaf length, leaf width, days to flower, days to 50% flowering, number of fruits/plant, fruit length, fruit diameter, fruit weight and 1000 seed weight suggest simple inheritance system and thus amenability for these attributes to selection in tomato improvement.
利用遗传变异参数研究了19份番茄材料的遗传变异程度。将四周大的幼苗以0.6 x 0.6的间距移植到平整的田地中，并在随机完全区组设计中复制三次。所研究的所有属性的材料之间存在高度显著差异。基于37个农业形态属性的聚类分析将材料按果实类型分为两个不同的类群。基因型和表型变异系数的值显示了材料之间的变异性。相关分析表明，果/株与株高、分枝/株数和叶长呈正相关。叶长、叶宽、开花天数、50%开花天数、每株果实数、果实长度、果实直径、果实重量和1000粒种子重量的非常高的遗传进展和遗传力估计表明，遗传系统简单，因此这些属性在番茄改良中可用于选择。

Chrysanthemum have significant ornamental value and thus have a great economic importance and are also subjected to losses due to the insufficient rooting of the cuttings the main method of vegetative propagation practiced for this crop. Insufficient understanding of the mechanisms that control adventitious root formation prevents the use of reliable technologies to improve the percentage of root adventitious development in cuttings of ornamental plants in general. Also, knowing the architecture of the root system helps correct application of chrysanthemum culture technologies. Two different cultivars of Chrysanthemum was investigated in order to describe the radicular architecture of cuttings, with emphasis on the root type and the influence of substrate on the developed model into four different variants of rooting substrate.

The discharge of heavy metals in the environment due to anthropogenic, industrial and automobile activities is a worldwide environmental pollution problem. Copper is widely used in different forms in fertilizer, fungicides. Industrial effluents and for the removal algal growth in ponds. In this study the toxic effects of copper (Cu) on seed germination and seedling growth of Lens culinaris were investigated. Germination rate of L. culinaris that showed that increased in concentration of copper treatment at 25 ppm significantly (p<0.05) reduced germination percentage as compared to control. Seedling growth variables i.e. root and shoot length, seedling size and root/shoot ratio also declined significantly (p<0.05) with the treatment of copper at 25 ppm as compared to control. Seedlings dry weight of L. culinaris gradually reduced with increased in all treatment of copper concentration as compared to control. Tolerance indices and seedling vigor index of L. culinaris also decreased with increase in concentration of copper treatment. Low percentage of reduction in tolerance indices and seedling vigor index of L. culinaris was recorded at 25 ppm copper treatment as compared to control. A high percentage of reduction in seedling tolerance indices of L. culinaris was recorded at 100 ppm of copper treatment as compared to control.

Castor oil plant (Ricinus communis L.) is an important oil crop with little research attention in Nigeria. In this research, studies on quantitative inheritance of spike characters in castor, through combining ability and generation mean analyses, were carried out. This was aimed at evaluating prominent seed yield related components for selection and hybridization in castor breeding in Nigeria. The result of combining ability analysis showed significant differences for both general combining ability (GCA) and specific combining ability (SCA) for number of spikes per plant (SPP), effective spike length (ESL), capsules per spike (CPS) and 100-seeds weight. Specific combining ability was important for seed yield (SY) and seed oil content. Broad sense heritability and narrow sense heritability of 28.02% to 99.64% and 10.28% to 72.19% respectively were recorded among the traits studied. The results of scaling and joint scaling tests revealed inadequacy of simple additive-dominance model to explain the mode of gene actions for all the studied traits. The six parameters model revealed that besides the additive and dominance gene actions, epistatic interaction mechanisms have also contributed significantly to the expressions of all the characters examined. These findings suggest heterosis breeding and recurrent selections as appropriate breeding techniques for the improvement of the traits. However, where additive gene actions are to be exploited in selection program for some of the traits, the problem pose by presence of epistasis gene interactions may be overcome through delay in selection to later generation when the major operating genes will be fixable.
蓖麻油料植物(Ricinus communis L.)是尼日利亚重要的油料作物，但研究较少。本研究通过配合力分析和代均值分析，对蓖麻穗性状进行了数量遗传研究。这是为了评估在尼日利亚蓖麻育种中与种子产量相关的重要组成部分，以便进行选择和杂交。配合力分析结果表明，单株穗数(SPP)、有效穗长(ESL)、每穗蒴果数(CPS)和百粒重在一般配合力(GCA)和特定配合力(SCA)上均存在显著差异。特定配合力对种子产量和含油量具有重要影响。广义遗传率为28.02% ~ 99.64%，狭义遗传率为10.28% ~ 72.19%。标度试验和联合标度试验的结果表明，简单的加性-显性模型不足以解释所有性状的基因作用模式。6个参数模型表明，除加性和显性基因作用外，上位互作机制对所有性状的表达也有重要影响。这些结果表明，杂种优势育种和循环选择是改善性状的适宜育种技术。然而，如果在某些性状的选择程序中利用了加性基因作用，则上位性基因相互作用的存在所带来的问题可以通过将选择延迟到后代，当主要的操作基因是可修复的时，来克服。

The floral vasculature aspects of twenty-four species belonging to six monocotyledonous families are dealt with. These selected taxa include 23 horticulture species cultivated in Egypt and the remainders is among the wild flora of Egypt. A great attention has been focused by phylogenetists on the position of the ovary with respect to the other parts of the flower. In this connection, the nature of the inferior ovary is generally discussed on the basis of two theories; appendicular and axial. It is fortunate that the vascular skeleton can still be regarded as the most conservative character and that it may be rather conclusive in the determination of the nature of the inferior ovary. In the present study, the different patterns of floral vascularization are presented in cumulative tables and figures to facilitate the comparative study. Moreover, an interpretation to the observed variations is also tried to reach at the relations between the taxa studied and to determine the nature of the hypanthium.

A field trial was conducted during the 2010 cropping season at the experimental farm of Akperan Orshi College of Agriculture, Yandev–Gboko, Benue State. The plots were laid in Randomized Complete Block Design with three replications. The analysis of variance showed significant in difference in nodule dry weight; days to 50% flowering; days to maturity; plant height at maturity; number of branches; number of pods per plant; number of seeds/ plant; and weight of 100 seeds among the genotypes studied. The result of this experiment conducted showed that there were highly significant correlation on number of pods per plant, number of seeds per plant, and significant correlation of one hundred seed with seed yield. The results of the path coefficient analysis also showed that number of pods per plant exerted the highest direct effect on seed yield. Weight (g) of one hundred seeds showed the least direct effect among the traits evaluated. The regression on seed yield and its component character also showed that number of pods per plant had the highest contribution to seed yield with the proportion due to regression being 48%. The relative contribution of number of branches per plant to seed yield was 2%.
