Anatomical variation in leaf lamina of ber seedling and budded plants grown at different sodicity levels

摘要

Pot culture experiments were conducted to study the effect of different sodicity levels on survival and anatomical changes in leaf lamina of wild jujube (seedlings) and cultivars, Banarasi Karaka, Kaithali, Umran and Gola after 18 months of establishment. Histological examination of leaf lamina showed differential response to graded levels of exchangeable sodium, resulting in either increase or decrease of the tissues. Among the budded plants, Banarasi Karaka recorded positive increase in size of vascular bundle (60.5 ESP), epidermal cell size, pallisade cell size (U.E.) at both the levels, i.e. (38.8 and 60.5 ESP). Seedlings showed marked increase in total number of xylem cell, followed by a marginal increase in pallisade cell (L.E) at 38.8 ESP. Survival of Seedlings and budded plants decreased significantly with the rise in sodicity levels. Umran and Gola failed to survive at 60.5 ESP with a very poor survival in Kaithali.
