- 摘要:
- 5月份对学校苗圃的四年生大扁杏幼树喷施不同浓度的天然芸苔素内脂，5～8月每月测定一次叶绿素、脯氨酸、可溶性糖含量和叶片饱和亏。结果发现，天然芸苔素内脂可以明显提高大扁杏的叶绿素含量，提高光合作用强度，增强大扁杏的抗旱性。同时发现，对大扁杏幼树喷施天然芸苔素内脂最佳浓度是0.20×10-6。
- Abstract:
- Four-year-old Prunus armeniaca×sibirica trees were sprayed with NBR of differnent concentration in May. Then it was determined for the content of chlorophyll, proline, soluble saccharide and saturation water deficit every month in May to August. The result found that NBR could improve the content of chlorophyll and the rate of photosynthesis of apricot, increase drought resistance. It also found that the appropriate concentration was 0.2×10-6 per tree.
