Abstract
Compatible and incompatible pollen tubes growing on detached Lilium longiflorum pistils which had been prelabeled with myoinositol-U-(14)C take up a portion of the label and utilize it for biosynthesis of tube wall substance. The label is transferred from pistil to pollen tubes apparently via the secretion products (exudate) of the pistil. The exudate thus appears to have a major nutritional role in pollen tube growth in vivo.
摘要
在预先用肌醇-U-(14)C标记的离体麝香百合雌蕊上生长的亲和与不亲和花粉管，摄取了一部分标记物，并将其用于管壁物质的生物合成。标记物显然是通过雌蕊的分泌产物（渗出物）从雌蕊转移到花粉管的。因此，渗出物在体内花粉管生长中似乎具有主要的营养作用。
