摘要
以6个不同类型水稻品种为供试材料,在结实期进行两种水培营养液浓度(标准Espino浓度和1/2 Espino浓度营养液)处理,研究营养液浓度对稻米品质的影响。结果表明,与1/2 Espino浓度营养液相比,结实期标准Espino浓度营养液增加了叶片叶绿素含量,降低了MDA含量;标准Espino浓度营养液显著或极显著地增加了稻米的垩白粒率、垩白度、蛋白质含量,降低了整精米率和胶稠度;稻米RVA淀粉谱参数受营养液浓度影响较大,标准Espino浓度营养液降低了RVA谱特征值中的最高粘度(PV)、热浆粘度(HS)、崩解值(Breakdown)、最终粘度(FV)和恢复值(Consistence),提高了消碱值(Setback)。
Abstract： Six rice cultivars were grown in nutrient solution and treated with two kinds of concentrations （the standard and 1/2 Espino prescription） of the solution during the grain filling period. The effects of nutrient solution concentrations on rice quality were studied. The main results were as follows ：The high nutrient solution concentration （tile standard Espino prescription）increased chlorophyll contents and decreased MDA contents when compared with the low nutrient solution concentration （1/2 Espino prescription）, significantly or very significantly increased, chalky rice percentage, chalkiness and protein content,while decreased head rice and gel consistency;the standard Espino prescription had lower PV,HS,Breakdown.FV and Consistence, while higher Setback.
