芽用花生籽仁吸水特性动态变化研究
Study on dynamic changes in water absorption characteristics of peanut kernels for sprouting
摘要
Abstract
[Objective]To investigate the dynamic changes in water absorption characteristics of peanut kernels for sprouting,thereby providing a theoretical reference for the breeding and production of sprouting peanut varieties.[Methods]Zhuhua 11,Zhu H23,Yuhua 93,Yuhua 9326,Luhua No.8,and Huayu 20 were used as experimental materials.The kernels were respectively placed in a water-bath electric thermostatic incubator at(25±2)℃,and water absorption capacity of sprouting peanut kernel was measured at different soaking times to analyze the dynamic changes in water absorption characteristics with soaking time.[Results]The water absorption capacity and water absorption ratio of peanut kernels for sprouting showed a continuous increasing trend with prolonged soaking time.When the water absorption capacity reached 50%,Zhuhua 11,Yuhua 93,Yuhua 9326,and Huayu 20 required 3 h of soaking,while Zhu H23 and Luhua No.8 required 4 h.When the water absorption ratio reached 50%,Zhuhua 11 required 7 h of soaking,Yuhua 93,Yuhua 9326,and Zhu H23 required 5 h of soaking,Huayu 20 required 24 h of soaking,and Luhua No.8 maintained a water absorption ratio below 50%throughout 1 to 72 h of soaking.The water absorption rate decreased gradually with prolonged soaking time,with the highest rate occurring during 0 to 1 h,a sharp decline from 1 to 2 h,a smaller decline from 2 to 6 h,and approaching a horizontal line after 36 h.The 100-grain volume and expansion rate increased continuously with prolonged soaking time.After 72 h of soaking,the 100-grain fresh weight of Zhuhua 11,Zhu H23,Yuhua 93,Yuhua 9326,Luhua No.8,and Huayu 20 increased by 61.49%,80.35%,65.32%,65.27%,55.75%,and 51.02%,respectively,compared to the initial dry weight;grain length increased by 16.94%,15.07%,11.17%,23.53%,12.59%,and 16.51%,respectively,compared to the initial grain length;and grain width exhibited a wave-like increase with prolonged soaking time.Spearson correlation analysis indicated that water absorption ratio and water absorption rate were extremely significantly negatively correlated with water absorption capacity,100-grain volume,expansion rate,100-grain fresh weight,grain length,and grain width(P<0.01);water absorption capacity was extremely significantly positively correlated with 100-grain volume,expansion rate,100-grain fresh weight,grain length,and grain width(P<0.01);and 100-grain volume,expansion rate,100-grain fresh weight,grain length,and grain width were also extremely significantly positively correlated with each other(P<0.01).[Conclusion]The longer and wider the peanut kernels for sprouting,the more favorable it is for increasing 100-grain volume,expansion rate,100-grain fresh weight,water absorption capacity,water absorption ratio,and water absorption rate.Yuhua 93,Yuhua 9326,and Luhua No.8 are excellent peanut kernels for sprouting with coordinated water absorption characteristics.关键词
