Effects of Chitosan on Seed Germ ina tion of L a rixolgensis and P la tyc ladus orien ta lis

LI Qing-mei; FU Zeng-juan; ZHANG Hong-yan

La rix olgensis and Platycladus orien talis seedswere soaked with different concentration of chitosan solutionin 0. 5, 1. 0, 1. 5 and 2. 0 g·L-1 with 24 hours and 18 hours in order to find the op timal germinating condition. Theresults showed that the germination percentage, germination energy, mean germination time and germination indexof Larix olgensis were significantly imp roved, and its op timal germinating condition was in 1. 0 g·L-1 of chitosansolution with 24 hours. The op timal germination percentage and mean germination time of Platycludus orientalis seedswere obtained under chitosan solution in 2. 0 g·L-1 with 24 hours.
