摘　　要：为探究基因型和环境及两者互作对棉籽中主要矿质元素含量的影响,以10个陆地棉品种在长江流域棉区10个试点的样品为研究材料,测定棉籽中7种矿质元素N、P、K、Na、Ca、Mg和S的含量,并进行相关分析。结果表明:基因型、环境及两者互作对棉籽中7种主要矿质元素含量均有极显著的影响;P含量与Mg、N与Na含量呈极显著正相关。棉籽中矿质元素含量主要受环境影响,但基因型及两者互作对其影响也不容忽视。在棉籽成熟过程中N、P、Mg同步积累,合理施用Na对棉籽矿质元素的积累有促进作用。这些结果为棉花种籽品质改良提供理论基础,并为棉花种籽的综合利用和棉花生产提供有益的借鉴。Plant genotypes, the environment, and their interaction, have important effects on mineral element levels in cottonseed. Seed samples of 10 upland cotton cultivars planted in 10 different locations in the Yangzi River region were collected to determine the levels of seven mineral elements including nitrogen （N）, phosphorus （P）, potassium （K）, sodium （Na）, calcium （Ca）, magnesium （Mg）, and sulfur （S）. Correlations between these elements were then analyzed. The results showed that the effects of genotype, environment and the interaction between genotype and environment on level of seven minerals in the cottonseed were extremely significant and that correlations between P and Mg, as well as N and Na, were extremely significant with correlation coefficients of 0.73 and 0.63, respectively. This suggests that the environment has more of an effect on mineral element levels than the genotype, although the effects of the genotype and the interaction between genotype and environment are also impor- tant. Our findings also indicated that N, P, and Mg are synchronously accumulated in cottonseeds as reasonable application of Na can accelerate the accumulation of these mineral elements. This study provides useful information around the use of fertiliza- tion to improve cotton seed qualities, cottonseed utilization, and cotton production.
