橄榄(Canarium album)种子形态结构与数量性状分析

Seed morphological structure and quantitative trait analysis of Canarium album

  • 摘要: 以福建主栽的橄榄(Canarium album(Lour.)Rauesch.)品种‘长营’种子为材料,观察其成熟种子及不同发育时期种子的形态结构,对数量性状进行测量与统计分析,并运用概率分级建立形态指标的正态分布分级标准。结果显示,橄榄种子表型性状和形态结构变异较大,各数量性状变异系数为6.77%~19.04%,具有丰富的遗传多样性;橄榄种子心室类型有12种,其中三心室占比最高(97.80%);胚数量0~4个不等;经K-S检验,各数量性状符合正态分布,依据各性状可划分为5级分级标准。本研究为橄榄种质的系统学研究提供了种子形态方面的新内容,可为橄榄资源描述的标准化及遗传育种研究提供一定的参考。

     

    Abstract: Seeds of the major cultivar Canarium album (Lour.) Rauesch. ‘Changying’ in Fujian were used as test materials. The morphological structure of the mature seeds and seeds in different developmental periods were observed, with quantitative traits measured and analyzed. We used probability grading to establish indices to grade normal distribution. Results showed that variations in seed phenotypic traits and morphology were large, and the variation coefficients of characters ranged from 6.77% to 19.04%, with abundant genetic diversity. There were 12 types of loculus features, with the proportion of three loculi accounting for 97.80%. The number of embryos varied from 0 to 4. According to the K-S test, all characters conformed to normal distribution, and could be divided into five grades. This study provides a new understanding of seed morphology for the systematic study of C. album germplasm as well as a reference for the standardization of C. album genetic resources and breeding.
