- 摘要:
- 以百花花楸带侧芽茎段为试材，研究了培养基配方中分别缺失氮磷钾元素的症状，以期为选择适合植物生长的培养基配方提供理论依据。结果表明：最早出现缺素症状的是缺氮培养，其次是缺钾培养和缺磷培养；根系活力、光合速率、叶绿素含量以及干重都是缺氮培养的花楸最低，其次是缺钾，缺磷表现相对较高，但也都显著低于对照。
- Abstract:
- Taking Sorbus pohuashanensis (Hance) Hed.l lateral stem segments with bud as test materials，the symptoms of N，P，K elements deficiency in the culture medium formulations were studied，in order to provide a theoretical basis for choose media formulations suitable for plant growth.The results showed that the earliest symptoms of nutrient deficiency was the lack of the N training，followed by the lack of K training and lack of P training；the root activity，photosynthetic rate，chlorophyll content and dry weight of lacking N training of Sorbus pohuashanensis were the lowest，followed by lack of K，lack the P performance was relatively high，but significantly lower than the control.
