Abstract

AbstractThe current study was done on peanut genotypes including one check.  This study aimed to characterize the morphological variance of genotypes using the Shannon-Weaver diversity index. The experiment was laid out in a simple lattice design. Among the genotypes about (46.94%) had erect growth habits, followed by (34.69%) decumbent-3, while decumbent-2 (12.24%), procumbent-1 (4.02%) and decumbent-1 were the least (2.04%). The genotypes revealed three different branching patterns such as alternate, sequential, and irregular with flowers on the main stem accounting (for 14.29%), (53.06%), and (32.65%) respectively. The majority of genotypes had red (46.96%) seed coat color followed by purple-red (22.45%). Purple, pink, and tan seed colors accounted for (12.24%), (10.20%), and (6.12%) respectively. The white seed coat color was observed for check. Among the studied traits the seed coat color (H'=1.44) had the highest diversity index, followed by leaf color (H'=1.29), pod beak (H'=1.20), and growth habit(H'=1.19), indicating that the presence of high diversity among genotypes for these traits. The diversity in qualitative traits might be good for varietal preference and marketability. This genetic variability can be useful for improvement programs. Therefore, it is recommended that studies should be conducted on molecular characterization besides morphological variabilities.

Abstract

Tomato (Lycopersicon esculentum L.) belongs to the Solanaceae family. It is a crop of immense economic importance worldwide and salinity is one of the major abiotic factors limiting it's production and productivity globally. The amount of irrigation water and their evapotranspiration is the main reason that causes salinization. Salinity is an abiotic stress that affects agriculture by severely impacting crop growth and, consequently, final yield. Considering that sea levels rise at an alarming rate over year, it is clear that salt stress constitutes a top-ranking threat to agriculture. Among the economically important crops that are sensitive to high salinity is tomato one that is more affected by salt stress. Si plays the beneficial role of the quasi-essential metalloid silicon (Si), which increases the vigor and protects plants against a biotic stresses. The use of silicon fertilization can be used as sustainable practices in agricultural production to increase yield and quality of plants. Silicon fertilization also plays role in plant protection against various range of exogenous stresses especially, under changing environment. The use of appropriate irrigation method, amount and water quality to minimize the risk of salt accumulation around root zone of plants. Different plant growth regulators and amino acids could also play a great role in increasing yield and growth of tomato under salt stress.
