贵州铜仁地区栽培油茶种苗生理特性及繁育技术研究

Research on Physiological Characteristics and Propagation Technology of Oi Camellia Germchit Which Cultivates in Tongren, Gnizhou Province

对贵州铜仁地区栽培油茶种子的生理特性、种苗繁育技术进行了一系列的试验研究。结果表明，不同激素和浓度对栽培油茶种子的发芽率和油茶扦插苗的成活率的影响存在明显差异，而不同的处理时间对其影响较小。在种子繁殖试验中，以200mg／L赤霉素处理的种子发芽率最高；在硬枝扦插繁殖试验中，以100mg／L的生根粉处理16h比其它处理的成活率高，在软枝扦插试验中，以150mg／L的生根粉处理20h的成活率最高；芽苗砧嫁接技术是一项无性繁殖的新技术，用于油茶生产中，可使油茶苗的栽培成活率达到90％以上，具有重要的推广应用价值。

A series of tests about physiological characteristics and seedling breeding technology of oil camellia seed which cultivates have been carried out in Tongren, Guizhou province. The results show that there are obvious difference in germination percentage and survival rate due to different hormone and concentration. In the seed breeding tests, germination rate of seed is the highest which treated with 200mg / L gibberellic. In hard branch cuttage test, 20h survival rate is the highest which disposed with 150mg / L rhizoqenesis powder; bud grafting technology is a new cloning breed technology, it can make growth survival rate of oil camellia bud reach more than 90%.
