摘  要:
[目的]通过水培试验,研究了采自华南地区20份割手密种质对铝胁迫的响应。[方法]比较各材料的相对耐铝值及其和综合耐铝系数的相关性分析。[结果]确定了相对根长、相对地上干物质和相对地下干物质,可作为割手密耐酸铝的的重要筛选指标。[结论]根据筛选体系,计算各材料的综合耐铝系数,筛选出A13、A20、A23等耐铝毒的割手密基因型和A31、A24、A50等对铝胁迫敏感的割手密基因型。

摘  要:
[Objective] A solution culture test was carried out on 20 high quality varieties or lines of Saccharum spontaneum L. from southern China for their response to aluminum stress. [Method] Their relative tolerance index,the correlation analysis and comprehensive evaluation coefficient were compared. [Result] Reative dry weight of plant root,relative DW of up-ground plant part and relative plant height could be considered as important indices for screening the aluminum tolerance of Saccharum spontaneum L. [Conclusion]The aluminum-resistant comprehensive coefficient was calculated using the critical indices,and A13,A20,A23 high tolerant genotypes and A31,A24,A50 low tolerant genotypes were selected.
