%X <span style=\"font-size:10pt;font-family:宋体;\">大豆是全球最重要的粮油作物之一，探讨大豆籽粒吸胀前后的外形变化对于揭示不同品种的籽粒吸胀特性、播种墒情选择和品种利用具有重要意义。研究利用</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">41</span><span style=\"font-size:10pt;font-family:宋体;\">个大豆品种</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">(</span><span style=\"font-size:10pt;font-family:宋体;\">系</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">)</span><span style=\"font-size:10pt;font-family:宋体;\">做试材，测定种子吸胀前后籽粒重量、粒</span><span style=\"font-size:10pt;font-family:宋体;\">体积</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">(</span><span style=\"font-size:10pt;font-family:宋体;\">按排水量计</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">)</span><span style=\"font-size:10pt;font-family:宋体;\">、粒长、粒宽和粒厚变化，进行相关分析、逐步回归分析和聚类分析。试验结果显示：</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">1) </span><span style=\"font-size:10pt;font-family:宋体;\">吸胀前后试验材料间籽粒特性差异明显，其中吸胀前后粒体积的变异系数最高，粒长和粒厚变异系数较小，而粒宽变异系数增加明显。</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">2) </span><span style=\"font-size:10pt;font-family:宋体;\">大豆籽粒吸胀前后所有籽粒性状</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">(</span><span style=\"font-size:10pt;font-family:宋体;\">粒重、粒体积、粒长、粒宽和粒厚</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">)</span><span style=\"font-size:10pt;font-family:宋体;\">间的简单相关系数都达到极显著水平。偏相关分析显示，只有粒重与其他籽粒性状的偏相关系数都表现显著正相关，偏相关系数大小顺序为粒长</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\"> <span>&gt; </span></span><span style=\"font-size:10pt;font-family:宋体;\">粒厚</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\"> <span>&gt; </span></span><span style=\"font-size:10pt;font-family:宋体;\">粒宽；而粒体积与粒长、粒宽和粒厚的偏相关不显著；粒厚与粒宽的偏相关系数基本保持稳定</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">(</span><span style=\"font-size:10pt;font-family:宋体;\">低负相关</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">)</span><span style=\"font-size:10pt;font-family:宋体;\">。粒长与粒宽和粒厚的偏相关性在籽粒吸胀前后存在差异：吸胀前粒长与粒宽显著而与粒厚不显著，籽粒吸胀后恰好相反。不同材料吸胀前后籽粒性状比及其相关系数也反映了同样的趋势。</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">3) </span><span style=\"font-size:10pt;font-family:宋体;\">大豆吸胀后粒重平均增加</span><span style=\"font-size:10pt;font-family:'Times New Roman','serif';\">2.03</span><span style=\"font-size:10pt;font-family:宋体;\">倍，粒体积增加</span><span
