摘要：

Seeds were collected at weekly intervals from mid-maturation to the fully ripened stage As seed development progressed, desiccation tolerance increased Desiccation tolerance of C lansium seeds was greatest at 67 days after anthesis (DAA), when they tolerated air drying for 9 days; 74 DAA was considered as physiological maturity, and their full viability was only maintained for up to 3 days of drying; overnpened seeds (88 DAA) had the lowest desiccation tolerance In L. chinensis, the desiccation sensitivity of seeds at 98 DAA (fully mature) was higher than that at 84 and 91 DAA (less mature); among the excised embryonic axes at different developmental stages, the less mature ones were less sensitive to desiccation than the fully mature ones; excised embryonic axes of the same stage were more tolerant of desiccation than whole seeds
