Genotypic differences in aluminum tolerance of cowpea accessions utilizing germination parameters

چکیده
One of the major factors which limit productivity cowpea on acid soils is aluminum toxicity. Reliable methods for identifying genetic variation its tolerance indispensable. Genetic variability in 10 accessions were studied laboratory. Fifteen seeds each accession sown sterilized petri dishes containing filter papers and 5 ml AlCl3 at four levels (0, 50, 100 200 µm) replicated three times a completely randomised design (CRD). Petri incubated under room temperature dark 48 hours. After hours, they exposed to photoperiod 12 hr. / (day/night) another At day after sowing, data collected percentage germination, number roots per shoot, fresh weight root length hypocotyl shoot. Data subjected statistical analysis arranged their stress by means indices. Analysis variance revealed significant effect all parameters. Treatment was excluding germination. length. The observed could be exploited hybridisation establish tolerant lines. Selection based high heritability GAM can selection.

Determination of Aluminum Stress Tolerance Threshold During Seed Germination of Wheat
Environmental stresses are the most important factors that reduce plant growth in stages of development. The presence of aluminum in acidic soils as an environmental stress has an impact on different parts of the plant and reduces root growth, water absorption and nutrients and increases susceptibility to drought. In order to evaluate the effect of aluminum stress levels on wheat at germinatio...
متن کاملGenotypic Variation in Seedling Tolerance to Aluminum Toxicity in Historical Maize Inbred Lines of Zambia
Maize (Zea mays L) is the most important food grain in sub-Saharan Africa and is mostly grown by small-scale farmers under rainfed conditions. Aluminum toxicity caused by low pH is one of the abiotic factors limiting maize production among smallholder farmers. Therefore, breeding maize hybrids that are tolerant to aluminum toxicity will sustain and increase maize production in these areas. Henc...
