Effect of sodicity on growth of polyembryonic mango rootstocks

In the present investigation, polyembryonic genotypes of mango Bappakai, Chandrakaran, EC95862, Goa, Kurukkan, Nekkare, Olour, Peach, Sabre, Starch and 13/1 were grown under greenhouse conditions in pots containing soil mixtures of varying ESP, viz., 9.10 (control), 15, 25 and 35. Growth of high sodium tolerant genotypes 13/1, Sabre and Olour upto 35 ESP and intermediate tolerant cultivars Bappakai, Nekkare and Kurukkan upto 25 ESP was better than other cultivars and the reduction in their growth was lesser in terms of stem length and diameter, number of leaf, size of leaf and fresh, dry weight of root than other genotypes.
