Flowering and Pollination Characteristics of Primula pseudodenticulata
摘要
Abstract
A field investigation was conducted on the floral syndrome and pollination characteristics of Primula pseudodenticulata in artificial population by continuous observation, out-crossing index, pollen-ovule ratio and fruit setting rate. The main results are as follows: Under artificial cultivation conditions, the population come into bloom from December to February of the following year. The flowering span for a plant is month to 1.5 months. The life span of one single flower was 9~14 days. Single flowers have long styles and short-style flower divided. The pollinating insects of P. pseudodenticulata are mostly bees, in addition to butterflies, flies. These indicate that the breeding system of P. pseudodenticulata is facultative selfing.关键词
