兰花是国际花卉市场上最畅销的花卉,每年销费量很大,如美国仅切花一项,年销费额就达5000～6000万美元。我国兰科植物资源丰富,有许多其他国家所没有的特有种,给兰花杂交育种提供了有利因素,惟野生的兰花在人工栽培条件下不易开花,欲使预先设计好的杂交组合父、母本花期相遇,更是困难。自1975年我们开始进行兰花杂交育种研究工作以来,往往由于父母本花期不遇,无法得到理想的杂交组合,如何将优良亲本的花粉块在保持生命力的情况下储存,以备随时应用,能按理想组合进行杂交,是急需解决的问题,经过较长时间的摸索,我们研究出干燥冷藏保存花粉块生命力的方法,两年的实践证明,此法用于兰花花粉块的保存是成功的。
Orchids are the best-selling flowers on the international flower market. They cost a lot of annual sales. For example, the United States cut only one flower and the annual sales amount reached 50 million to 60 million U.S. dollars. Our orchidaceous plants are rich in resources, and many endemic species not found in other countries, which provide favorable conditions for crossbreeding of orchids. However, the wild orchids are not easy to flowering under artificial cultivation conditions. In order to make the pre-designed hybrid combinations parent and female Flowering encounter is even more difficult. Since 1975 we began orchid hybrid breeding research work, often because of the parents of the flowering period, can not be the ideal hybrid combination, how the fine parental pollen blocks in the vitality of the storage, ready for use, according to the ideal Combination of hybridization is an urgent need to solve the problem, after a long time to explore, we developed a method of dry and cold preservation of the vitality of pollen blocks, two years of practice has proved that this method for the preservation of orchid pollen blocks is successful.
