Maxim is a traditional Chinese medicinal plant with important value for curing several diseases, including liver cancer. Seed germination, field seedling emergence, and morphological and physiological traits were measured in developing seeds of , which were collected at 7, 14, 21, 28, and 35 days after flowering. The results showed that with the fruit pericarp changing from lime green to dark red, the seed volume increased. Furthermore, the dry mass of seeds gradually increased from 0.011 g at 7 d to 0.275 g at 35 d, which was a significantly positive correlation with seed vigour (r = 0.980). The soluble protein content initially increased and then decreased to 11.09 mg/g and presented a maximum at 28 d; however, the soluble sugar content gradually declined to a minimum of 30.45 mg/g at 35 d, which was also significantly negatively correlated with seed vigour (r = -0.915). Furthermore, the unsaturated fatty acids (oleic acid and linoleic acid) increase with seed development. Abscisic acid (ABA) reached a maximum value of 18.45 ng/g at 28 d, and gibberellin (GA), 3-Indoleacetic acid (IAA) and zeatin-riboside (ZR) initially increased and then decreased. These results suggest that the vigour of seeds is closely associated with their stage of development, with the highest vigour observed at 28~35 d after flowering.
麦仙翁是一种具有重要药用价值的传统中药材,可用于治疗多种疾病,包括肝癌。对开花后7、14、21、28和35天采集的麦仙翁发育种子进行了种子萌发、田间出苗以及形态和生理特性的测定。结果表明,随着果实果皮从石灰绿变为深红色,种子体积增大。此外,种子干重从7天时的0.011克逐渐增加到35天时的0.275克,与种子活力呈显著正相关(r = 0.980)。可溶性蛋白含量先增加后降至11.09毫克/克,并在28天时达到最大值;然而,可溶性糖含量逐渐下降至35天时的最低值30.45毫克/克,这也与种子活力呈显著负相关(r = -0.915)。此外,不饱和脂肪酸(油酸和亚油酸)随着种子发育而增加。脱落酸(ABA)在28天时达到最大值18.45纳克/克,赤霉素(GA)、3-吲哚乙酸(IAA)和玉米素核苷(ZR)先增加后减少。这些结果表明,麦仙翁种子的活力与其发育阶段密切相关,在开花后28至35天观察到最高活力。
