Comparation Test on High-Quality Flax Resources for Oil and Fiber Production in Kazakhstan

ABSTRACT

Oil flax stems are often burnt because of the low fiber content; this issue is especially serious in Kazakhstan. To solve this problem, this study aimed to determine which flax resources could exhibit a significant increase in stem yield without a decrease in seed yield. In a previous study in 2019, we tested seven types of flax stems at the research site of the S. Seifullin KATU campus. Here, a further investigation of the same resources, which was conducted in 2020, is described. According to the results, the UF03, UF05, and UF06 showed higher dynamics of plant height in the budding and blooming stages compared to a local Kazakhstani variety; this result greatly differed compared with the data from 2019. UF03 yielded the best oil quality, especially in terms of the linolenic acid and linoleic acid contents. UF02 had good performance in terms of yield and the largest fat content of all resources. More foreign flax resources should be introduced to improve the development of the flax industry in Kazakhstan.

摘要

油用亚麻常因茎的纤维含量低而被丢弃焚烧，这个问题在哈萨克斯坦尤为严重。 因此，发掘出茎产量高、种子产量不降低的亚麻资源成为了本研究的重点。2019年，我们在位于哈斯克斯坦的赛福林农业技术大学基地试验了7种不同亚麻资源的产量情况。在此基础上，本研究于2020年对这些资源进行了进一步研究。研究结果表明，与哈萨克斯坦当地资源相比，UF03、UF05和UF06在现蕾期和花期表现出更高的株高，这与2019年的试验结果一致。UF03油脂品质最佳，亚麻酸和亚油酸含量显著高于其他资源。UF02在产量方面表现较好，并拥有最高的脂肪含量。因此，引进更多的国外亚麻资源对促进哈萨克斯坦亚麻产业的发展，很有必要。
