種（zhǒng）子生活力是指種子發芽的潛（qián）在能力或種胚所具有的生命力[9]。種子生活（huó）力是種子（zǐ）質量鑒定項目中重要檢測內容，是判定種子質量優（yōu）劣的重要指（zhǐ）標[10]。毛萼紫薇種子（zǐ）的生活力較低。而自（zì）然條件下（xià），江蘇紫薇花瓶（píng）批發的（de）觀賞討論（lùn）與結論毛萼紫薇結實率很高，但自然萌（méng）發率很低，這（zhè）可能與種子的生活力低有關。研究發現，種子成熟采收後，有些（xiē）種子的種胚已經褐化、變硬。在萌發實驗中，褐化變硬（yìng）的種子不再具有萌發能力。由此可見，毛萼紫薇種子生活力低，一方麵有可能是種胚在發育過程中已經褐化死亡，從而喪（sàng）失萌發能力；另一方麵有可能（néng）是（shì）種子具有一定的休眠特性，種子需要經過（guò）一定時間的存儲後才能完成生理後熟。

Seed viability refers to the potential ability of seeds to germinate or the vitality of the embryo. Seed viability is an important testing content in seed quality appraisal projects and an important indicator for determining the quality of seeds [10]. The viability of the seeds of Lagerstroemia tomentosa is relatively low. Under natural conditions, the ornamental discussion and conclusion of Jiangsu crape myrtle are that the fruiting rate of hairy calyx crape myrtle is high, but the natural germination rate is low, which may be related to the low viability of the seeds. Research has found that after the seeds mature and are harvested, some of the seed embryos have become brown and hard. In the germination experiment, seeds that have turned brown and hardened no longer have the ability to germinate. From this, it can be seen that the viability of the seeds of Lagerstroemia tomentosa is low. On the one hand, it is possible that the embryo has already brown and died during the development process, resulting in a loss of germination ability; On the other hand, it is possible that seeds have certain dormancy characteristics, and they need to be stored for a certain period of time to complete physiological ripening.
As an ornamental plant with beautiful tree shape, bright flower colors, and a long flowering period for disease and pest control in Sichuan Ziwei, Ziwei plays an important role in the field of landscaping and greening. This article takes the biological characteristics and main distribution of crape myrtle as the starting point, elaborates on its cultural value and artistic expression, analyzes its application in gardens, and sorts out its cultivation, maintenance, and management work based on cultivation management, breeding methods, pest control techniques, and pruning and shaping techniques, providing reference for relevant researchers. Ziwei, also known as Bairi Red and Pruritus Tree, belongs to the family Lyciaceae and belongs to the genus Ziwei, which is a deciduous shrub or small tree. It has the characteristics of fast growth, strong adaptability, and wide distribution range. Sichuan Ziwei manages disease and pest prevention and control, and relevant garden designers should further strengthen their attention to Ziwei tree species, targeting their design ideas Further in-depth and detailed research on application methods and cultivation and maintenance processes has significantly improved the quality and level of landscaping, laying a more solid foundation for the synchronous development of ecological and ornamental value of gardens.
Fujian Ziwei Old Pile Wholesale and Management Training; Observe once a day, record the number of germinated seeds, calculate the seed germination potential [9], germination rate, and randomly select 10 growing seedlings to measure their plant height, number of lateral roots, longest lateral root length, and other indicators. The wholesale and management data of Fujian Ziwei Laozhu was analyzed using SPSS 19.0, and the Duncan method was used to compare the effects of different concentration gradients of plant growth regulators on various growth indicators. Formula calculation: live seeds/%=number of viable seeds/number of experimental seeds × 100 germination rate/%=number of germinated seeds/number of trial seeds × 100 germination potential/%=Gpt/Dpt × In the l00 formula, Fujian Ziwei Laozhuang Wholesale and Management Gpt refers to the germination amount at the peak day, while Dpt refers to the number of days when the peak value is reached. 2 Results and Analysis 2.1 Seed Viability After 2 months of dry storage at room temperature, the seed viability of Lagerstroemia tomentosa was relatively low, only 13.3% (N=90).
