Abstract:
Abstract: The low field nuclear magnetic resonance (LF-NMR) detection technique was used to study the effects of different seed soaking methods and soaking solution on rice seed water absorption for finding a better seed soaking method. In the test, the transverse relaxation time T2 inversion spectrum was used to study the change of rice seeds water status and water absorption characteristics. It was found that the soaking process can change the distribution of the moisture inside the rice seed. The seed water absorption capacity were not significant (P>0.05) to the initial moisture content rate, but were significant (P<0.05) to different soaking methods. The results show that the seed water absorption rate is the highest using the intermittent soaking method of soaking 2 h-drying 1 h-soaking 2 h in the 4 kinds of different seed soaking methods of 4 h continuous soaking, soaking 3 h-drying 1 h-soaking 1 h, soaking 2 h-drying 1 h-soaking 2 h and soaking 2 h-drying 2 h-soaking 2 h. The seed water absorption rate is the highest using the 40% formalin 50 times liquid in the 6 kinds of different soaking solutions of pure water, strong chlorine 300 times liquid, saturated clarification lime water, 40% formalin 50 times liquid, 40% formalin 100 times liquid and 40% formalin 200 times liquid. The experimental results can provide an effective method for the determination of moisture absorption in the seed soaking process, also provide the data support and theoretical basis for seeking the best soaking condition.
