Abstract

An experimental trial was conducted to study the effect of different pre-sowing treatment for overcoming seed dormancy in seeds of Fraxinus xanthoxyloides (Wall. ex G. Don) DC. The seeds were collected from the naturally growing trees in Kirunkhud area of Pooh Block of Kinnaur district during October 2007. The seeds were subjected to seven pre-sowing treatment having different concentration of gibberellic acid ranging from 500ppm to 3000ppm including control to study their effect on germination behavior. Significant differences were observed for all the germination parameters viz., germination percentage, mean daily germination (MDG), peak value (PV), germination value, germination speed and germination energy percent of the seeds treated with different concentration of gibberellic acid. The result indicates that seeds of Fraxinus xanthoxyloides treated with GA3 1500ppm for 24 hours recorded highest germination percent, germination energy percent, germination speed and mean daily germination (MDG) and proved to be best treatment for overcoming seed dormancy and also to improve seed germination. The best treatment registered a 54.34 % increase in germination percent over control.
