摘要: 【目的】探究芽用花生籽仁吸水特性动态变化规律,为芽用花生品种选育与生产提供理论参考。【方法】以驻花11、驻H23、豫花93、豫花9326、鲁花8号、花育20为试验材料,分别置于隔水式电热恒温箱[(25±2) ℃]内,测定不同浸泡时间下芽用花生籽仁的吸水量,分析其吸水特性随浸泡时间的动态变化。【结果】芽用花生籽仁吸水量、吸水率随浸泡时间的延长呈持续增加趋势,吸水量达50%时,驻花11、豫花93、豫花9326、花育20需浸泡3 h,驻H23、鲁花8号需浸泡4 h;吸水率达50%时,驻花11需浸泡7 h,豫花93、豫花9326、驻H23需浸泡5 h,花育20需浸泡24 h,鲁花8号浸泡1~72 h吸水率均低于50%;吸水速率随浸泡时间的延长逐渐降低,浸泡0~1 h吸水速率最高,1~2 h急剧下降,2~6 h降幅变小,36 h后趋近于水平直线;百粒体积、膨胀率随浸泡时间的延长持续增加;浸泡72 h,驻花11、驻H23、豫花93、豫花9326、鲁花8号、花育20百粒鲜重比初始干重分别增加61.49%、80.35%、65.32%、65.27%、55.75%、51.02%,粒长比初始粒长分别增加16.94%、15.07%、11.17%、23.53%、12.59%、16.51%,粒宽随浸泡时间的延长呈波浪式增加。Spearson相关性分析表明,吸水率、吸水速率与吸水量、百粒体积、膨胀率、百粒鲜重、粒长、粒宽呈极显著负相关关系(P<0.01),吸水量与百粒体积、膨胀率、百粒鲜重、粒长、粒宽呈极显著正相关关系(P<0.01),百粒体积、膨胀率、百粒鲜重、粒长、粒宽之间也呈极显著正相关关系(P<0.01)。【结论】芽用花生籽仁越长、越宽,越有利于百粒体积、膨胀率、百粒鲜重、吸水量、吸水率、吸水速率的增加;豫花93、豫花9326、鲁花8号是吸水特性协调的优良芽用花生籽仁。

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.
