1979—1982年在呼和浩特气候条件下,我们研究了15—52个红花(Carthamus tinctorius.L)类型的适应性。可以把这些类型划分为两个部分,第一部分为地方类型;第二部分是从国外引入的品种。据红花适应性的反应,结论如下: 1、据红花在呼和浩特生育期表现,可以将红花分为极早熟、早熟、中熟和晚熟种。 2、据红花适应性表现,将其生态型区分为感温敏感类品种和感光敏感类品种。适应性强的品种有B—54、油红花、uc—26。 3、红花某些性状间单相关测定表明,均未达到显著程度,但均为正相关。初步认为增加分枝数可以增加花球数目;株高与分枝为弱相关关系;株高与茎粗几乎无相关系。 4、籽粒产量在不同年分表现不稳定,主要受气候、发病程度的影响。
1979-1982 In Hohhot climatic conditions, we studied the adaptability of 15-52 Carthamus tinctorius .L types. These types can be divided into two parts, the first part is a local type; the second part is introduced from abroad. According to the adaptive response of safflower, the conclusions are as follows: 1, according to the performance of safflower growth period in Hohhot, safflower can be divided into very early, early maturity, maturity and late-maturing species. 2, according to safflower adaptive performance, the ecological type is divided into temperature sensitive varieties and photosensitive sensitive varieties. Adaptable varieties are B-54, oil safflower, uc-26. The single correlation analysis of some characters of safflower showed that they did not reach the significant level, but all were positively correlated. It is preliminarily believed that increasing the number of branches can increase the number of curd; the plant height and branch are weakly related; the plant height and stem diameter have almost no correlation. 4, grain yield instability in different years, mainly affected by climate, disease severity.
