Abstract
An experiment on "Salt tolerance in seedlings of some commercial ber (Zizyphus mauritiana, Lamk.) varieties" was undertaken during the year 1990-91 at Mahatma Phule Agricultural University, Rahuri, Maharashtra. Eight commercial varieties of ber, namely, Sanaur-6, Manukhi, Chhuhara, Umran, Dandan, Mehrun, Kadaka and Glory, were grown in saline soil (EC 4.5 dSm" ) and in normal soil (EC 0.66 dSm" ). Data are presented on germination percentage, plant height, stem diameter, leaf number, primary root length, fresh and dry weight of shoot and root and contents of leaf chlorophyll *a' and ' b* and leaf N, P and K. All the parameters studied, decreased in saline soil. Considerable variation was observed among the different varieties in all the parameters that were studied. Out of the eight commercial varieties of ber chosen for the study, the varieties Dandan, Umran and Chhuhara have shown better adaptability to salinity level of EC 4.5 dSm"1.
