New plant growth regulators, named chloroisosulochrin, chloroisosulochrin dehydrate and pestheic acid, have been isolated from the culture filtrate of Pestalotiopsis theae grown on a Raulin-Thom medium. Their structures have been established by spectroscopic and chemical methods. The biological activities of these compounds have been examined using bioassay methods with lettuce and rice seedlings
从在Raulin-Thom培养基上生长的茶树病毒菌培养液中分离出了新的植物生长调节剂,命名为氯异苏洛金、氯异苏洛金脱水物和佩斯酸。它们的结构已经通过光谱和化学方法确定。使用生物测定方法对这些化合物的生物活性进行了检查,使用的试验对象为莴苣和稻米幼苗。
