青海省不同马铃薯品种对硒的吸收特性研究
Selenium Absorption Characteristics of Different Potato (Solanum tuberosum) Cultivars in Qinghai Province
摘要
Abstract
[Objective ] To determine the potato varieties with high selenium absorption and accumulation ability in selenium-enriched area of Qinghai Province, so as to provide scientific theoretical basis for the development of selenium-enriched industry in this area. [Method] A random group arrangement was designed, Se spraying treatment and no Se spraying treatment were designed, main processing for selenium, selenium respectively set processing and spraying selenium treatment; Deputy processing varieties for processing, for Qingshu 168, Qingshu 9, Qingshu 2 three varieties, repeated 3 times, 18 treatments. [Result] In no Se treatment group, Se concentrations in potato tuber decreased in the order of Qingshu 2 > Qingshu 9 > Qingshu 168; in Se treatment group, Se concentrations in potato tuber decreased in the order of Qingshu 2 > Qingshu 168 > Qingshu 9. With Se spraying or not, the Se concentration in all three potato cultivars was at a high level. With the extending growth period of potato, Se concentration in the tuber of Qingshu 168, Qingshu 9 and Qingshu 2 presented a single valley declining tendency, and reduced to the minimum value at the 82nd day after seedling emergence. [Conclusion] With Se spraying or not, Se concentration in all three potato cultivars was at a high level, especially in Qingshu 2. With the extending growth period of potato, Se concentration in the tuber of three cultivars presented a single valley declining tendency.关键词
