    Abstract:

    In order to understand the seed characteristics and the rhythm of seedling breeding of Tutcheria kweichowensis, the biological characteristics, including seed thousand grain weight, viability, water content and water absorption, the germination rate of seeds under different storage methods, the annual growth rhythm of seedlings were studied. The results showed that the thousand grain weight, viability and water content of seeds were 0.920 kg, 66.17% and 11.75%, respectively, and the maximum water absorption was up to 15.62%. Low temperature wet sand storage could be used for long-term storage, while short-term accelerating germination was suitable for wet sand storage at 25℃, relative humidity 80% for 40 days, seed germination rate could reach more than 80%. The annual growth rhythm of the seedlings was "slow-fast-slow". The active growth period was from May to September, the seedling growth in height and ground diameter accounted for 65.48% and 42.02% of the year, respectively. Therefore, according to the growth characteristics, it would have great significance to improve the seedling quality and production efficiency by adopting different seedling measures in different growth stages, strengthening field management and the supply of water and fertilizer.
