Germination profile of babul (Acacia Nilotica) under different salinity conditions
DOI:10.5958/2230-732X.2014.01394.1
Abstract:
Babul (Acacia nilotica) is an important multipurpose, leguminous tree species, grown widely under agroforestry systems in India, Middle-East Asia, and Africa. It is an important source of fodder, fuel, timber, gum and medicines. The salinity tolerance ability of Babul in 15 provenances (Sagar, Jabalpur, Raipur, Nagpur, Akola, Khandwa, Ujjain, Shajapur, Bhopal, Guna, Jhansi, Bharatpur, Jaipur, Rewari, Karnal) were investigated using petri dishes and poly bags. The solutions of different compound like sodium chloride, sodium bi-cardonate, calcium chioride, magnesium sulphate and calcium sulphate was prepared with five level of salinity concentration, which have electrical conductivity of 3, 6, 9, 12 and 15 dSm-1, respectively. Among the five doses of salinity, the highest does EC 15 dSm-1 was found most deleterious to the seed germination of Babul in all the provenances. Out of 15, ten provenances had more than 50% reduction in germination at EC 9.0 dSm-1. Akola, Khandawa, Guna and Jaipur provenances were least affected by the increased level of salinity under both the test i.e., petri dishes and poly bags and hence these provenances may be called as most tolerant to salinity.
