Abstract
A novel plant growth regulator, pironetin, was isolated from the culture broth of Streptomyces sp. NK10958. It was extracted from the culture broth with ethyl acetate and purified by column chromatographies. Pironetin showed 23% inhibition on the growth of rice plants without any loss of crop yield at 10 g/a on 9 days before heading.
摘要
一种新型植物生长调节剂——吡喃奈汀，是从链霉菌属NK10958的培养液中分离出来的。它用乙酸乙酯从培养液中萃取，并通过柱色谱法进行纯化。在抽穗前9天，以10克/亩的用量施用吡喃奈汀，对水稻植株生长有23%的抑制作用，但作物产量无任何损失。
