Progress in the Researches on Pollen Contamination in Seed Orchards of Forest Trees

林木种子园花粉污染是影响种子园种子遗传品质的重要因子,本文综述了国外林木种子园花粉污染研究的概况、污染水平、影响污染水平的因子、减少污染的措施等。并对我国种子园花粉污染研究和花粉管理提出了建议。

The pollen contamination in a seed orchard is a principal factor influencing thegenetical quality of a seed orchard. In this paper a review is made of the general researcheson pollen contamination, contamination level, the extent of its infuence and the measures toreduce it in seed orchards in foreign countries. Researches show that in a seed orchard thecontamination level is higher than that formerly estimated; pollen yield seems to have no in-fluence on contamination level; space and physiological isolation are not so effective as to beexpected. At present time, SMP is the most effective measure to reduce pollen contamina-tion. The authors make some recommendations about reasearch on and management ofpollen contamination in seed orchards in China.
