ABSTRACT
Wafaa Mohamed Sharawy Abdel-Fattah, physiological genetic studies on some characteristics of Trifolium alexandrinum L., unpublished Doctor of Philosophy, Genetics, Fae. of Agric., Ain Shams Univ., 1997.
Eleven accessions of berseem clover (Trifolium alexandrinum L.) were grown in the field with sufficient irrigation (every 15 days) and two drought stress irrigations (every 21 and 30 days). The results indicated that morphological parameters, photosynthetic rate, stomatal conductance, intercellular CO concentration and osmotic potential were higher in irrigation every
15 days than irrigation every 21 and 30 days. Water stress caused a reduction in fresh and dry yield. Subsequently, accessions 1, 11 and 26 were selected as drought tolerant while accessions 6, 27 and 66 were drought sensitive.
Marked association was observed between praline content and ion ratios and drought tolerance. This study also showed a reduction in callus growth at higher levels of water stress.
SDS-protein, isozyme electrophoretic patterns for esterase, acid phosphatase and peroxidase and molecular markers (RAPD) were effectively discriminated between the tolerant and sensitive
