Abstract

The influence of salinity, given at germination (stage I) or 75 d after sowing (stage II), on flower production and characteristic features of male reproductive structures was studied in three promising genotypes of chickpea (Cicer anetinum L. cv. ICCV 88102, H 82-2 and C-235). In ICCV 88102 and H 82-2 salinity 20 meq 1-1 increased the number of flowers when applied at both stages whereas in C-235 only when applied at the later stage. The salinity also delayed flowering; the higher salinity the greater was delay in flowering. In H 82-2 and C-235 salinity treatment given at stage II (when few flower buds appeared) hastened the flowering. The salinity curtailed pollen production; the reduction being minimum in C-235 and maximum in H 82-2. Germination was not significantly affected in C-235 pollen collected from plants grown under salinity conditions upto 60 meq 1-1 applied at stage I but the tube elongation was inhibited. The inhibition of tube elongation was greatest in C-235. Salinity treatment administered at stage II did not affect significantly pollen germination excepting C-235 in which a consistent decline with increasing salinity was evident. Salinity stimulated tube growth in ICCV 88102. Na2SO4 in the germination medium was more detrimental for both pollen germination and tube growth than NaCI.
