ABSTRACT

This paper gives a short reviewof the research on the seed and seedling characteristics and morpho-physiological and biochemical response of some bean cultivars (Phaseolus vulgaris L) exposed to salinity, high temperature and drought at the seedling stage and discusses the factors affecting pod and seed production. Bean cultivars showed large variabilities in seed and seedling traits, thereby, offering a great opportunity in selecting genotype for desirable traits. Various factors influence the seed quality, viability, the seed vigour and early seedling growth. Bean cultivars showing significant genotypic variability in germination, seedling growth and mineral acquisition among genotypes and among different abiotic stresses (salinity, high temperature and seedling drought) offered good opportunity for the selection of genotypes resistant to different stress factors. On the basis of the results, it may be mentioned that the rate of imbibition, germination, accumulation of soluble sugars, minerals and proteins may be considered as indicators for the selection and genetic improvement of bean cultivars of resistance to different abiotic stress factors. The accumulation of soluble sugars in the germinating seeds and mineral elements in the seeds and seedling in stress situations are considered as osmostic t1djustment in these stresses
