Effects of delayed sowing-date on yield components of Thladiantha setispina / 中草药

ABSTRACT

Objective: In order to discuss the influence difference of environmental stress on dioecious plants and the response of environmental factors influence on the fruiting and yield of Thladiantha setispina. Methods: The effects of the different sowing-dates on the female plant rate, fruit character, and seed yield of T. setispina were investigated by the comparative ways. Results: Different sowing-dates on differentiation of male and female plants had a significant impact. The appropriate delay of sowing-date could significantly improve the proportion of female T. setispina (P 0.05), but the sowing-date on yield components of T. setispina had a direct impact on related indicators, yield differences during the treatments reached a very significant level (P < 0.01). Conclusion: The appropriate delaying of sowing-date could help to improve the seed production of T. setispina.
