BHARDWAJ, N. (Dept. Bot., Univ. Rajasthan, Jaipur, India) 1985. Effect of Temperature and Photoperiod on growth and reproduction of Tephrosia species. Jap. J. Ecol., 35 : 193-197. The paper describes the results of a field and an experimental study of the effects of temperature and photoperiod on the growth and flowering of Tephrosia apollinea and T. hamiltonii which are common perennial weeds in the semiarid areas of Rajasthan. The plants remain leafless and dry during the winters. The old shoot sprouts during March when the atmospheric temperature starts rising. The plants flower throughout the summer and rainy season. The experimental studies show that the two species are, quantitative intermediate plants (Plants flower under all day lengths but flower best when the day is neither too short nor too long). These growth and flowering is largely governed by the temperature factors, and atmospheric temperature above 30℃ during the day being essential for the bud sprout, leaf growth and flowering.
