水稻的穗型参数

PARAMETER OF EAR TYPE OF RICE

摘要:

用必要的穗型参数对穗部性状进行定量的数字表达具有精确而可比的特点。本文以水稻穗结构特性为依据,对与穗型有关的性状进行了分析,提出了有关穗部性状的9个参数公式,并用实际测得的数据进行了运算,结果证明这些参数公式合理,简便,实用,对水稻株型育种及栽培具有重要的理论意义和实用价值。

Abstract:

Quantitatively numerical descriptions on the characters of rice panicle using panicle type parameter were both accurate and comparable. Based on the characteristics of rice particle structure, the study analyzed the characters relating to panicle types and proposed nine parametric formulae concerning panicle characters. Operations on data from experiments showed that apart from logical, simple and practical. These parametric formulae also have great theoretical significance and practical value in plant type breeding and cultivation of rice.
