Abstract

Seeds of kusum (Schleichera oleosa) exhibits physical and physiological dormancy.A study on “Effect of Presowing treatments on the propagation of Schleichera oleosa” was conducted during 2021-22.Kusum seeds were subjected to nine treatments which includes GA3 (100, 300, 500, 1000 ppm), H2SO4 (3, 5, 10 min) and cold stratification for improving their germination and growth performance by breaking dormancy exhibited by seed in the present study. Various germination parameters viz germination and survival percentage, germination energy, germination period and growth parameters like root length, shoot length, number of leaves, collar diameter, dry weight of shoot and root, shoot: root ratio for seedlings were observed. GA3 of 1000 ppm for 24 hours reported highest germination percentage, survival percentage, germination energy, dry weight of shoot and root and shoot: root for Schleichera oleosa while root length, shoot length, number of leaves, collar diameter were significantly higher with GA3 of 100 ppm for 24 hours treatment.
