types of plant reproduction

    

It seems humans are not the only species having to make sacrifices a recent report by Zhongjian Liu and co-workers at the National Orchid Conservation Center in Shenzhen suggests that orchids are also cutting down on sexual reproduction for something else.

The researchers discovered a species of orchid,  Trias verrucosa, growing in the forest of Gaoligong Mountain in West Yunnan, China. They found many cloned offshoots around the orchid, but could not find any fruits or seeds produced by the plant, nor signs of their remains.

Liu and co-workers then looked more closely at how the orchid blooms after natural pollination, artificial self-pollination and also artificial cross-pollination. They found that the orchid could flower in all cases, but the flowers were short-lived, lasting four to five days, and no fruit was produced.

In its natural habitat, the orchid blooms a month before the rainy season — a time of dryness, strong wind, low temperature and weak light, which are all unfavorable conditions for blooming. Based on these findings, the researchers hold the opinion that the orchid might have abandoned sexual reproduction. Instead, the plant has invested all its resources in asexual reproduction, by ending its fruitless flowering as soon as possible. This reproduction strategy might be ecologically advantageous for the orchid living in such hostile conditions.

Response:

Plants can reproduce in three ways that are cross-pollination and self-pollination each one is a funjdamental way of a plant to reproduce itself, the male part of the flowers is the stamen and the female is the pistil which are used for the reproduction.

Most flowers use cross-pollination to reproduce cause is the safest way to reproduce themselves than with the wind and the self pollination .
