不同花生品种荚果发育及有机物积累动态研究

Study on changes of organic composition and development of peanut pod among different peanut cultivars

黄淮区花生不同品种荚果发育动态及有机物积累过程的研究表明 ,86 0 36 - 2 6 - 1荚果发育早、速度快 ,持续时间短 ;海花 1号发育晚、速度慢 ,持续时间长。不同品种籽仁干物重、脂肪及蛋白质积累的差异主要表现在快速增加阶段。 86 0 36 - 2 6 - 1籽仁的各种有机物增加快而多 ,但籽仁脂肪含量及蛋白质含量较低 ;豫花 7号的各种有机物增加较快而多 ,蛋白质含量和脂肪含量较高。

The development of peanut pod and organic substance accumulation of different cultivars in the region of Huanghe river and Huaihe river were studies. The results showed that 86036-26-1 exploded earliest, most rapidly and it lasted shortest; in contrast, Haihua No.1 exploded latest, most slowly and it lasted longest. The differences of dry weight, lipid and protein accumulation process in peanut kernel among cultivars appeared mainly in rapid increase stage. The organic substance of 86036-26-1 accumulated most and rapidly; but the percentage of lipid and protein contents were lower. The organic substance of Yuhua No.7 accumulated more and rapidly, and protein and lipid content were higher.
