马尾松雄花枝性状研究几年来对马尾松雄花枝（着生雄球花的短枝）作了一些试验：花枝长度与雄花数目的关系；花枝上球花出粉量；花粉含水率、体积等。这方面的资料，国内未见有报道，但它对杂交育种和花粉交易中合理使用劳力、花枝采集量、花粉的保存等均具理论和生产实践... Some studies have been made on the male flowers of Pinus massoniana in the past few years: the relationship between the length of flower branches and the number of male flowers; the output of flowers on flowering branches; the moisture content and volume of pollen. There are no reports in this field in China, but it has theoretical and production practices for rational use of labor force, collection of flowering branches and preservation of pollen in hybrid breeding and pollen trade.
