种子吸水速率的测定,一般是连续称重吸水种子而得。Butcher和Stenvert(1973)以及Stenvert和Kingswood(1976)应用氚水和自动射线照像术,研究水分向小麦籽粒中渗透的速率。称重法测定种子吸水速率的困难之一,是种子表面的游离水。一般用吸水纸除去游离水。这对称重需要增加时间,使需要同时测定种子的份额数目受到限制。本研究初步探索使 Determination of seed water absorption rate, the general is continuous weighing water-derived seeds derived. Butcher and Stenvert (1973) and Stenvert and Kingswood (1976) used tritiated water and autoradiography to study the rate of water infiltration into wheat grains. One of the difficulties in determining the rate of seed water absorption by the gravimetric method is the free water on the seed surface. Generally use absorbent paper to remove free water. This need to increase the time for the weighing, so that the need to simultaneously determine the number of seeds is limited. This research explores
