冬小麦穗分化的形成期是决定每穗粒数的关键时期之一,较准确地鉴定麦穗分化进程,对正确掌握麦田的肥水管理有十分重要的意义,因此,探索简捷准确的小麦穗分化进程的鉴定方法,已成为引人注意的问题.目前,在水稻上有二种鉴定穗分化的方法,一种是日人松岛省三在1957年提出、目前生产上广泛应用的叶龄指数法(叶龄指数=?×100%)另一种是我国丁颖教授1959年提出、近年由凌启
The formation phase of winter wheat spike differentiation is one of the key periods to determine the grain number per spike. It is very important to correctly identify the process of wheat ear differentiation in order to correctly grasp the fertilizer and water management in wheat field. Therefore, to explore the simple and accurate wheat spike differentiation process Identification method has become an attractive problem.At present, there are two methods of identifying panicle differentiation in rice, one is the Japanese Matsushima three proposed in 1957, the current production of widely used leaf age index method (Leaf age index =? × 100%) Another is China’s Professor Ding Ying in 1959 proposed by Ling Kai
