Abstract
Excretory products from aphids feeding on flowering and vegetative Xanthium plants contained a cytokinin active in the soybean-callus assay. No cytokinin activity was found in honeydew collected from aphids feeding on a chemically defined diet. Soybean-callus assays indicated that honeydew from aphids feeding on flowering plants contained more cytokinin than honeydew from vegetative plants.
摘要
从吸食开花和营养期苍耳的蚜虫中排泄出的产物含有一种在大豆愈伤组织测定中具有活性的细胞分裂素。从吸食化学定义饮食的蚜虫中收集的蜜露中未发现细胞分裂素活性。大豆愈伤组织测定表明，从吸食开花植物的蚜虫中排泄出的蜜露比从营养期植物中排泄出的蜜露含有更多的细胞分裂素。
