四棱豆发芽和生育特性的初步研究

Preliminary Study on Germination and Growth Characters of Winged Bean

研究了１５、２５和３５℃三种温度下四棱豆的发芽特性以及三播期下的生育特性．结果表明，随着温度的升高，正常发芽率提高，非正常发芽率和霉烂率下降，且以浸种为优．不管早播还是迟播，初花期均在９月初；花荚脱落的高峰期在开花后的２～５天，总脱落率为７０％以上．

The germination characters under three temperatures and growth character in three sowing dates of winged bean were studied in this experiment. It was showed that normal germinating seed rate was increased, abnormal germinating and rotten seed rate were decreased with the temperature rising, and germination characters were better for soaked seed. The flowering stage was the beginning of Sept.whatever early or late sowing.The peak of flowering and young pod dropping was during the second to fifth days after flowering and the total dropping rate was over 70 percent.
