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。Taking Sorbus pohuashanensis （Hance） Hed. 1 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.
