为了探索苏铁的人工授粉和种子育苗繁殖,我们对开花铁树进行了人工授粉试验,取得成功。一、人工授粉 1.准备工作:备好毛笔和白纸,并注意观察雌雄花的成熟特征,充分抓住授粉的有利时机。一般讲,雄花成熟时,小孢子叶球变成鲜黄色,呈圆椎柱状,高度增至43—59厘米,直径达11—12.5厘米,且小孢子叶从下向上裂开。当裂开1/3或1/2时,小孢子囊背缝线即开裂,花粉开始散落,并发出浓郁
In order to explore artificial pollination of cycads and breeding of seedlings, we conducted artificial pollination experiments on the fern trees and achieved success. First, the artificial pollination 1. Preparation: Preparation of brush and white paper, and pay attention to observe the mature characteristics of male and female flowers, and fully seize the favorable opportunity of pollination. In general, when the male flower is mature, the microsporophyll leaves turn bright yellow in a cylindrical column with a height of 43-59 cm and a diameter of 11-12.5 cm. The microsporophyll leaves split upward from below. When split 1/3 or 1/2, microsporangiosal back suture that cracking, pollen began to fall, and issued a rich
