通常利用大豆种子室内发芽检验,估计种子在田间确保密度的能力。标准法发芽检验常用来测定大豆种子生活力。在几乎理想的条件下,这种检验准确地估计了田间出苗(Egli等,1979)。但在气候寒冷、土壤潮湿等不利田间条件下,这种检验往往过高估计田间出苗率(Athow等,1974)。为更好地估计不利条件下的田间出苗特性,已设计了几种“生活力”检验方法。其中寒 The indoor seed germination test of soybean seeds is usually used to estimate the ability of the seed to ensure density in the field. Standard method germination test commonly used to determine the viability of soybean seed. Under almost ideal conditions, this test accurately estimates emergence in the field (Egli et al., 1979). However, in unfavorable field conditions such as cold weather, moist soil, etc., such tests often overestimate the rate of emergence in the field (Athow et al., 1974). To better estimate the emergence of unfavorable conditions in the field, several “viability” tests have been devised. Which cold
