Effect of Photoperiod on Linum usitatissimum L. Characters

ABSTRACT

The review summarizes diverse knowledge about the problem of Linum usitatissimum L. response on photoperiod. Within this species, high genetic variability of the photosensitivity degree and influence of photoperiod on different plants characters were discovered. It was shown that in flax, earliness of flowering in long daylight is not strictly related to the low photosensitivity, and late genotypes with low photosensitivity can be found. In short daylight, various plant characters of different genotypes can be stable or display different reactions: increase or decrease their values. Also, the degree of photosensitivity does not have stable correlations with agronomic characters.

摘要

综述了近年来人们对光周期线性噪声响应问题的认识.在本种中，发现了光敏感度的高遗传变异性和光周期对不同植物性状的影响.结果表明，亚麻在长光照条件下开花的早度与光敏感度低没有严格的关系，并且可以发现光敏感度低的迟发基因型.在短日光下，不同基因型的各种植物性状可以稳定或表现出不同的反应：增加或减少其值.光敏感度与农艺性状也没有稳定的相关性.
