不同催芽方法对文冠果种子发芽率的影响

以文冠果种子为试验材料，采用低温（-18℃）雪藏90d、低温（0℃-5℃）沙藏90d和热水浸种（始温80℃）120h三种方法处理种子，然后在15℃-25℃条件下增温催芽10d，在25℃沙床上进行发芽观测，结果表明：三种方法处理的种子发芽率分别为79％、77％和39％，差异极其显著。以低温雪藏处理的发芽效果最好，低温沙藏次之，热水浸种效果最差、不宜采用。

Effects of different pregermination method on Xanthoceras Sorbifolia Bunge seeds

Xanthoceras sorbifolia Bunge seeds were taken as experimental materials, three methods was adopted to deal with the seeds： low temperature（ - 18℃ ） snow storage for 90 d, low temperatures（0℃ - 5℃ ） sand storage for 90 d and soaking of seeds with hot - water for 120 h（ the beginning temperature was 80 ℃ ）, after that, warmed the seed to accelerating germination for 10 d under the condition of 15 ℃ - 25 ℃, and germina- tion observation was proceed on the sand bed with 25 ℃, the results indicated that germination percentage of seeds of three methods were 79% ,77% and 39% ,respectively, and the differences were extremely significant. The best germination effect was low temperature snow storage, low temperatures sand storage took second place, and soaking of seeds with hot - water had the worst effect, so the method should not be adopted.
