茶树高产育种
high-yield breeding of tea plant

茶树高产育种(high一yield breeding oftea plant)以选育产t高的茶树新品种为主要目标的一种育种方法,包括改善产量结构的育种和改进生理过程的株型育种。产t结构是指茶树在单位面积内的芽叶数,和芽叶重t,以及单位时间内的生长速度和全年生长期的长短,即“多、重、快、长”四个因子。多和重是属于空间范围;快和长是属于时间范礴。四项因素同时具备而且有一项因素突出,就可得到高产。例如以一定芽数为基础增加芽重,或在芽,基础上增加芽数。茶树芽叶数和芽重在达到一定水平后.也会出现彼此间的负相关,因此高产育种就要研究构成产t因素的基本特征和薄弱环节,以选育水平较高的品种。 20世纪60年代以来.作物育种上的一个重要发展是从重视产t结构到株型选育.即通过提高作物的光合作用效率,特别是净光合率来选育高产品种,引用株型概念,用以指导茶树育种达到高产的植株形态。茶树是异花授粉作物,在无性系品种间或有性系品种内的株型差异显著,株型不同.形态就不同,它所占据的空间不同而导致产量、品质、适应性的差异。高产的茶树株型结构,是指具有高光合能力、低呼吸消耗、叶面积适当、长相及长势较理想的株型。根据株型理论和已知的研究结果,一般可通过四个方面的测定.即①叶片着生角度,②叶面积指数,③光饱和点或光补偿点,④根系活力。(陈国本)
