Chemical analysis of seeds and seedlings of the CC and cc genotypes in Melilotus ulhu indicated that these alleles affect flavonoid biosynthesis. The CC seed coats contained orientin and iso-orientin, which were absent in the cc seed coats. The pigment responsible for the red pigmentation of young seedlings of CC genotypes was a cyanidin glycoside. The embryos of seeds of both the CC and cc gen...

Germination and vigor are physiological components of seed quality that contribute to a successful plant emergence under wide range environmental conditions. Many biotic abiotic factors can affect quality. Tomato spotted wilt virus (TSWV) causes one the most relevant problems in peanut (Arachis hypogaea L.), tomato disease (TSW). Although TSW is not transmitted by seed, presence symptoms on coa...

Phosphorus (P) is an important element for crop productivity and is widely applied in fertilizers. Most P fertilizers applied to land are sorbed onto soil particles, so research on improving plant uptake of less easily available P is important. In the current study, we investigated the responses in root morphology and root-exuded organic acids (OAs) to low available P (1 μM P) and sufficient P ...

Field experiment had been done Research and Production Station, National Research Centre, Nubaria location, to study the effect of cobalt on growth, seeds yield, oil yield and oil fatty acids constituents. The experiment containing 13 plots area were 15 m (5 X 3) containing 3 rows each, planted with 10 plants. The seedlings (at the third truly leaf) were irrigated with cobalt sulphate once with...

Soil salinization, one of the most common causes soil degradation, negatively affects plant growth, reproduction, and yield in plants. Saline conditions elicit some physiological changes to cope with imposed osmotic oxidative stresses. Inoculation plants bacterial species that stimulate their i.e., growth-promoting bacteria (PGPB), may help counteract saline stress, thus improving plant’s fitne...

self-incompatibility is one of the main problems in almond production. in this research work, at the first step, some local cultivars as well as some imported ones were evaluated from the point of their male and female organ compatibility. then, ten selected commercial self-incompatible cultivars(female parents) were crossed with two self-compatible cultivars(male parents) i. e. tuono and super...
