This reduces the time required to produce a generation of seed. Major , D.J. 1980. Environmental effects on flowering. Continuous light is the most suitable method for reducing the time to flowering of long-day plants. For short day plants, short daylengths promote development.
Temperatures vary for suitability for rapid seed production.
Generally, between 25 and 35 C is desirable depending on cool vs. warm season plants and species. Moisture stress may be used to reduce the time between flowering and maturity. Care should be exercised to prevent seed abortion. Soil fertility should be limited to the amount needed to produce a smaller plant with fewer seeds. High population densities often appear to hasten maturity - probably related to fertility and nitrogen stress.
