摘 要: | 为明确不同功能叶对啤酒大麦籽粒灌浆特性的影响,采用单因素随机区组设计试验方法,对高产、优质啤酒大麦‘甘啤7号’的籽粒灌浆特性进行了研究,应用Logistic方程对灌浆进程进行了拟合。结果表明:不同光合器官处理下啤酒大麦灌浆进程符合Logistic生长曲线,呈“慢-快-慢”“S”型变化。不同处理对品种12项灌浆参数及麦芽品质均产生影响,但影响的具体参数和影响程度因处理而异。不同处理下产量性状指标筛选率和千粒重变化最大,且呈正相关关系。其中T4处理下,饱满粒(72.17%)和千粒重(42.37 g)与其他处理及CK产生显著差异。为选育高产、优质啤酒大麦,在育种选择实践中应综合考虑形态指标。

Effect of Different Functional Leaf on Grain-filling in Malting Barley |
| |
Abstract: | Mon-factor Randomized Complete Block Design (RCBD) experiment was conducted to analyze the effect of different functional leaf on the characteristics of grain-filling in malting barley cultivar (‘Ganpi7’). Variance analysis on yield and qualities based on the fitting result of grain-filling process via Logistic Growth Equation (LGE). The results indicated that grain-filling of malting barley cultivar best fits LGE under different treatments of functional leaf, with an S-like breakthrough curve of slow-fast-slow trend. The levels of different functional leaf influence 12 grain-filling parameters and malting qualities of malting barley, with both affected parameters and degree of effect varying with treatment. Effect of different treatments on screening rate and 1000-grain weight was significant and the change between them was apparently positive. The T4 treatment was significant different than others (screening rate: 72.17%, 1000-grain weight: 42.37 g). In order to breed hi-yield and high-quality malting barley, we should consider morphology index comprehensively in practice. |
