摘要
杂交水稻幼穗分化开始时叶龄余数值到底是３．０还是３．５或４．０？笔者认为，不管是常规水稻还是杂交水稻，绝大多数品种或组合幼穗分化开始时其叶龄余数值应是３．０，不是３．５，更不是４．０。
In the paper Studies on the Pattern of Leaf-panicle Synchronous Development of HybridRice and Its Application published in No.41995 issue of HYBRID RICE, Mr. Liu. Zhenyu et al concludedthat the remaining leaf number was 4.0 for hybrid rice at the beginning of young panicle differentiation. Butthe author here holds a different idea that the remaining leaf number is about 3. 0 rather than 3.5 or 4. 0 formost of rice cultivars, regardless of types(inbred rice of hybrid rice),and indicated that correct judging ofheart leaf of sampled plants is key in judging the remaining leaf number.
