棉铃的铃室数目受遗传特性决定,同一株上的棉铃主要有四室和五室区分。不同室数的棉铃与产量和品质性状有什么关系呢?1986年,我们经过初步试验研究,得出如下结果(采样部位均为第6果枝的第2果位棉种用本所新育的品系9106)。在大田栽培条件下,不同室数棉铃考种结果是:五室和四室的单铃种子数分別为40.4和32.0,手扯长度分别为31.5和31.2,单铃重分別为5.2和3.9,衣分率分别为37.1和37.8,籽指分别为9.4和8.9,衣指分别为5.54和5.41,单铃皮棉分別为1.93和1.47,细度
The number of bolls bell chamber is determined by the genetic characteristics, the same strain of cotton bolls have four and five compartments. What is the relationship between yield and quality traits in different numbers of bolls? In 1986, after preliminary experimental research, we got the following results 9106). Under the field cultivation conditions, the test results of cotton bolls with different number of rooms showed that the numbers of single bell in five-compartment and four-compartment were 40.4 and 32.0 respectively, the hand pulling lengths were 31.5 and 31.2, the single boll weights were 5.2 and 3.9 respectively Fractional rates were 37.1 and 37.8, respectively, the index finger 9.4 and 8.9, the fingers were 5.54 and 5.41, respectively, single boll lint cotton 1.93 and 1.47, the fineness
