氮肥用量不足導致穗葉葉肉細胞葉綠體結構性差，維管束鞘細胞碳水化合物累積減少，營養體氮素再分配率大而引起葉片早衰；而過量供氮則導致生長後期硝酸還原酶活性過高，氮素代謝過旺，消耗了大量碳水化合物，以致下位葉不能得到充足的碳水化合物供應而提早脫落，同時葉肉細胞葉綠體片層結構膨脹，呈「肉汁化」特徵，維管束鞘細胞澱粉粒大量消耗，無核澱粉粒出現，從而葉片葉綠素含量下降，光合能力降低而出現早衰。The results indicated that liangyoupeijiu showed better plant and leaf type, higher ratio of grains to leaf area and larger photosynthesis area, stronger ability of population dry matter accumulation during the period of vegetative growth especially from heading to being mature, longer leaf duration and grains - filling after heading than that of its parents and controls s ; more grains per panicle, lager all sink per plant and 1000 - grain weight
