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.
