【摘要】 为探索白檀果实形态变化与油脂积累的相关性,对生长发育过程中果实的大小、重量、含水率及含油率等指标进行定期观测和相关性分析。结果显示:白檀果实形态发育大致可划分为3个时期:果实快速生长期、果实缓慢生长期和果实颜色变化期。果实含水率随果实发育成熟逐渐下降,而果实含油率随果实生长成熟逐渐上升,两者呈极显著负相关,果实含油率在果实缓慢生长期显著增加,与鲜重干重呈极显著性正相关。成熟果实最高含水率51.2%,果实最高含油率可达到36.6%。更多还原

【Abstract】 During the process of fruit development of Symplocos paniculata,fruit’s longitudinal diameter,transverse diameter,fresh weight,dry weight,moisture content,oil content were measured regularly,and relationship between the fruit morphological development and oil accumulation process was analyzed.The result showed that the morphological development progress of fruit can generally be divided into three periods: fast growing of fruit size,slow growing of fruit size and the period of color change of pericarp.The moisture content of fruit decreased along with fruits growing up,the lowest moisture content was 51.2%,when fruit was mature.Meanwhile oil content of fruit increased with the fruit growing up,and the highest oil content was up to 36.6% when it matured.The correlation between oil content and moisture content was negative,but the correlation between oil content and fresh weight and dry weight was positive.更多还原
