Abstract
To study the conditions required for the development in vernalization stage of peas and broad beans,a series of field experiments were carried out and the results are summarized as follows: Peas and broad beans were able to complete their vernalization stage of de- velopment under 0°—20° C.or even higher.Within the above mentioned temperature range,10°C.was more suitable than 0℃.;and apparently temperatures higher than 10℃.were even more suitable as indicated by the more rapid development under higher temperatures. When vernalization treatment was applied to the seeds in germinating condition the effect on hastening the emergence of flower bud was more significant when seeds were sown in June than when they were sown earlier;and the effect was also more significant with late varieties than with early varieties. When germinating seeds were treated at 0°—10℃.,the time necessary for the completion of vernalization stage was longer than 20—25 days.With seedlings unber field conditions the development in vernalization stage advanced more rapidly than with germinating seeds under artificial vernalization treatment.From spring to summer the time required for the completion of vernalization stage under field conditions shortened with the delaying of date of sowing. Based on the facts given above,it may be hypothesized that the effect of vernalization treatment on hastening the emergence of flower bud is determined by the relative length of the period required for the plant to complete its development in the vernalization stage after it has emerged from the soil as compared with the period required for the plant to accumulate those special nutritive substances indispensable for the development in photostage and the differentation of reproductive organs.
