以8个自交系配制的56个玉米杂交组合为试验材料,对子粒脱水速率、子粒果皮厚度及子粒大小性状进行测定与分析。结果表明,子粒果皮厚度和子粒大小对子粒水分有一定影响,果皮厚度与子粒脱水速率呈负相关,与子粒含水量呈正相关;子粒的长、宽、厚均与子粒脱水速率呈正相关,且子粒长与子粒脱水速率的相关性显著。 Fifty-six maize hybrids from eight inbred lines were used as test materials to measure and analyze the dehydration rate, the pericarp thickness and the grain size traits. The results showed that the thickness of peel and the size of the seeds had an impact on the moisture content of the seeds. The thickness of the peel was negatively correlated with the dehydration rate of the seeds and positively correlated with the moisture content of the seeds. The length, width and thickness of the seeds were positively correlated with the dehydration rate of the seeds, The correlation between length and grain dehydration rate was significant.
