- 摘要:
- 为研究油用向日葵种子形态发育特性，本研究分析了3份油用向日葵保持系种子发育不同时期,子实和籽仁长度、宽度、厚度及种皮厚度的变化特点。结果表明：L-1-OL-1和改〖KG-*5〗HA89子实和籽仁长度在各个发育时期无显著变化，86-1子实和籽仁长度在开花后12 d相比于开花后7 d显著增加，其他时期无显著变化；子实宽度均在种子发育前期显著增大，之后趋于稳定；籽仁宽度均在种子发育前期显著增大，之后3份材料的变化趋势存在一定差异；子实和籽仁厚度均在种子发育前至中期逐渐增加，之后略有降低或呈小幅度变化，但3份材料变化趋势转变的时间点有所差异；种皮厚度在种子发育不同时期均表现为先增加后降低的趋势
- Abstract:
- In order to study the seed mophological development characteristics of oil sunflower,this study analyzed the variation characteristics of the length,width,thickness of seed and kernel and the thickness of seed husk in three oil sunflower maintainer lines at different stages of seed development.The results showed that the seed and kernel length of L-1-OL-1 and modified HA89 had no significant change at each development stage,the seed and kernel length of 86-1 increased significantly at 12 d after flowering compared with 7 d after flowering,and there was no significant change at other stages; the seed width increased significantly at the early stage of seed development,and then tended to be stable; the kernel width increased significantly at the early stage of seed development,and there were some differences among the three materials after that;the thickness of seed and kernel increased gradually from pre-to middle stage of seed development,and then decreased slightly or changed slightly,but the time points of trend change of three materials were different;the seed husk thickness increased firstly and then decreased at different stages of seed development.
