我省松树种类较多,除已普遍作为山地造林的马尾松、黑松外,又陆续从国外引进了火炬松、湿地松、晚松、短叶松、等松树,特别是火炬松和湿地松具有生长快、适应性强、病虫害少等优良特性,已逐步成为我省淮河以南丘陵山区的主要用材树种之一.因此,研究掌握火炬松、湿地松等松树开花的生物学特性,以便人工促进开花结实,开展人工杂交育种,不断提高种子产量,以及选育良种具有十分重要的意义.近几年未,我省正在进行火炬松、湿地松的人工辅助授粉试验.为了进一步搞好这一项工作,特将有关松树开花的生物学特性作些介绍,供有关单位参考.
There are many types of pine in our province. In addition to the masson pine and black pine, which have been widely afforested in mountainous areas, we also successively introduced pine, slash pine, evening pine, gypsophila paniculata and other pine trees, especially loblolly pine and Pinus elliottii It has become one of the main tree species in the hilly and mountainous area south of the Huaihe River in our province.Therefore, it is necessary to study the biological characteristics of pine flowering such as Pinus taeda and Pinus elliottii, Promote the flowering and fruiting, carry out artificial hybrid breeding, continuous improvement of seed yield, and breeding of seed has very important significance.In recent years, our province is undergoing manual auxiliary pollination of loblolly pine, slash pine in order to further improve this Work, especially about the biological characteristics of pine flowering for some introduction, for the relevant units for reference.
