摘要
H 的成熟种子。 salicifolia ,从五起源镇定(即 Hanuman Chatti , Helang , Lata , Rambara 和 Janggal Chatti )在西方 Himalaya ,印度,与层化被对待(在为 15 , 30 和 60 天的 4 °C )并且在 GA <SUB>3</SUB>的不同集中( 5 , 10 , 20 公里), KNO <SUB>3</SUB>( 50 , 100 , 200 公里)并且硫脲( 50 , 100 , 200 公里)在种子萌芽决定变化的答案。结果表明从在不同预先播种的处理下面的不同起源的种子的萌芽率显著地在控制与那些相比被增加(24%30%) 。与硫脲(100 公里) 对待的种子有最高的萌芽率(76%83% 为不同种子采购原料) ,由那些列在后面(63%71% 为不同种子采购原料) 有层化的 pretreated (4 ° C, 30 天) 。GA3 处理显著地弄短吝啬的萌芽时间(MGT ) 并且改善种子发芽率。考虑实际适用性和费用有效性,硫脲(100 公里) 和层化(在 4 ° C ) 为种子萌芽的处理通过 H 的种子为集体增加被推荐。在西方 Himalaya 的村庄 / 森林托儿所的 salicifolia,印度。
Mature seeds of H. salicifolia, collected from five provenances (i.e. Hanuman Chatti, Helang, Lata, Rambara and Janggal Chatti) in west Himalaya, India, were treated with stratification (at 4℃ for 15, 30 and 60 days) and in different concentrations of GA3 (5, 10, 20 mM), KNO3 (50, 100, 200 mM) and Thiourea (50, 100, 200 mM) solution to determine the variations in seed germination. Results reveal that the germination rates of seeds from different provenances under different pre-sowing treatments are significantly increased compared to those in control (24%-30%). The seeds treated with Thiourea (100 mM) have highest germination rate (76%-83% for different seed sources), followed by those (63%-71% for different seed sources) pretreated with stratification (4℃, 30 days). GA3 treatment significantly shortens the mean germination time (MGT) and improves seed germination percentage. Considering the practical applicability and cost effectiveness, thiourea (100 mM) and stratification (at 4℃) treatments for seed germination are recommended for mass multiplication through seeds of H. saliciifolia in village/forest nurseries of the west Himalaya, India.
