| 摘 要： | 以波叶红果树Stranvaesia davidiana var. undulata种子为试验材料，通过设置不同的果实储藏方式、不同的萌发温度和光照条件，对其种子萌发特性进行研究。结果表明:用室温干藏，低温（4 ℃）干藏，自然低温湿砂层积处理波叶红果树果实后，种子发芽率达极显著差异（P＜0.01），以自然低温湿砂层积处理种子发芽率最高，达41.3%；在10，15， 20，25，30，15/10，25/15，30/20 ℃ 等8个不同温度条件下，种子发芽率达显著（P＜0.05）和极显著差异（P＜0.01），在25 ℃条件下种子发芽率最高，达45.3%；在全黑暗、光照12 h（1 030 1x）和光照24 h（1 030 1x）等3个条件下，种子发芽率无显著差异（P＜0.05），说明波叶红果树种子为光不敏感种子或光中性种子。因此，波叶红果树果实经自然低温湿砂层积处理后，在25 ℃条件下，有利于提高种子发芽率，光照不是其种子萌发的必需条件。图1表3参16

| Abstract: | To provide a theoretical basis for the introduction，cultivation，and regeneration of Stranvaesia davidiana var. undulata，seed germination characteristics were studied using different methods of fruit stor-age（dry storage indoor at state temperature，dry storage at 4 ℃，and in wet stratified sand at natural temperature） as well as different germination temperatures（10，15，20，25，30，15/10，25/15，30/20 ℃） and lighting conditions（full dark，lighting 24 h，and lighting 12 h）. The results showed a highly significant differences（P＜0.01）on seed germination percentage for the three different fruits storage methods with maximum seed germination percentage （41.3%） reached using the wet stratified sand at natural low temperature. For temperature，significant differences（P＜0.05）on seed germination percentage were noted with maximum seed germination percentage of 45.3% at 25 ℃. For the three different light conditions，no significant differences（P＜0.05） were found. Thus S. davidiana var. undulata seed was neither photosensitive or photoblastic. Overall，fruit storage in wet stratified sand at natural temperature with seed germination at 25 ℃ was best with light not a determining factor.［Ch，1 fig. 3 tab. 16 ref.］ |
