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.
