Selection and breeding of the strain for production of acid ALPA - amylase
酸性α-淀粉酶生产菌株的选育的初步研究
-
But the difference of ALPA activity in rhizosphere is not significant among the genotypes .
根际碱性磷酸酶在基因型间差异不显著。
-
Low phosphorus condition also made ALPA activity in rhizosphere rise , the contents of soluble protein and soluble P in leaf reduce .
低磷胁迫下,根际碱性磷酸酶活性升高,叶片中可溶性蛋白含量、可溶性磷含量降低。
