TL;DR: The investigation was done to select the genotype(s) with good fibre yield and distinct features in respect of developing high yielding Tossa jute variety for cultivation in the farmers’ field, and this genotype O-0412-9-4 was selected based on higher plant height, base diameter, fibre yield content.
Abstract: An investigation was done to assess the genetic variability, character associations, and genetic diversity of eight jute genotypes for seven morphological traits in a randomised complete block design at Bangladesh Jute Research Institute during 15 March, 2018 to 31 December, 2019. Analyses results revealed significant differences (P<0.01) among all genotypes for studied traits indicating the presence of variability. All the lines performed better than one control (JRO-524), and the line (O-0412-9-4) provided good results for desired traits than all controls. Jute fibre yield showed the highest broad sense heritability (98.54%). The studied jute morphological traits i.e. Plant population, the plant height, green weight, dry fibre yield and dry stick yield gave high heritability along with high genotypic and phenotypic variances, genetic advances in percent of the mean, highly significant and positive correlations. It indicates the possibility of crop improvement through phenotypic selection and maximum genetic gain, simultaneously at the genotypic-phenotypic level. Clustering analysis grouped all genotypes into three distinct clusters. The cluster II showed the highest mean values for all traits followed by cluster I and III. The first two principal components with higher Eigen values (>1.0) accounted for 90.88% of the total variation in the principal component analysis. PCA and cluster analyses indicated that the advanced breeding line O-0412-9-4 made its individual cluster II with higher inter-cluster distance and higher fibre yield (3.12 t ha-1). The investigation was done to select the genotype(s) with good fibre yield and distinct features in respect of developing high yielding Tossa jute variety for cultivation in the farmers’ field. This genotype O-0412-9-4 was selected based on higher plant height, base diameter, fibre yield content. It will be developed as a high yielding variety considering its’ higher genetic variability, heritability, genetic advance, significant associations for desirable characters.

TL;DR: The antifertility nature of methanol extract of C. reflexa stem and C. olitorius seed is established and the increased rate of enzymatic activity might be associated with elevated level of progesterone induced by these methanolic extracts.
Abstract: The effects of multiple intraperitoneal doses of methanolic extract of Cuscuta reflexa Roxb. stem and Corchorus olitorius Linn. seed on the activity of carbonic anhydrase in the uterus of micewere studied. These methanolic extracts caused a significant increase in the carbonic anhydrase activity in the uterus of mice. The increased rate of enzymatic activity might be associated with elevated level of progesterone induced by these methanolic extracts. This further establishes the antifertility nature of methanol extract of C. reflexa stem and C. olitorius seed.

TL;DR: The results suggested that the fresh leaf extract of C. album may be a possible tool for the development of weed control using natural herbicides.
Abstract: The effects of water extracts of Chenopodium album leaves and roots on the growth of grass weed (Setaria viridis) and broad leaf weed (Corchorus olitorius) grown with beans (Phaseolus vulgaris) in greenhouse pots were studied in the National Research Centre, Giza, Egypt. In this experiment fresh leaf and root extracts and their corresponding dry leaf and root extracts at different concentrations were used. There were significant inhibitions in the dry weights of S. viridis and C. olitorius by all extracts at the flowering stage of beans and at harvest. The inhibition effect of all C. album extracts on both weeds (dry weight/pot) depended on the extracted plant organ (leaf or root), its fresh or dry form as well as its concentrations. The inhibition caused by the leaf extract was much higher on weed growth than that of root extract. A higher concentration of fresh leaf extract (25%) had the highest significant inhibition effect. The results also indicated that C. olitorius was more sensitive to the extracts than S. viridis. On the other hand, the inhibition effect of the extracts on the growth of both weeds was accompanied by increased bean growth and yield/plant. The analysis of both leaf and root extracts of C. album revealed that the total content of polyphenols and flavonoids in the leaf extract was more than triple that of the root extract. The results suggested that the fresh leaf extract of C. album may be a possible tool for the development of weed control using natural herbicides.

TL;DR: The percent GS3 content of the seed oil and of its interesterified product have been determined by the combined techniques of thin layer chromatography on silver nitrate impregnated silica gel and colorimetry.
Abstract: Corchorus olitorius seed oil and its randomised product have been subjected to pancreatic hydrolysis. Glyceride compositions have been calculated from the original fatty acid composition and those of the monoglycerides produced by hydrolysis. The percent GS3 content of the seed oil and of its interesterified product have also been determined by the combined techniques of thin layer chromatography on silver nitrate impregnated silica gel and colorimetry.
