１９８９－１９９５年实验证明：定植“左山一”茎尖６－７代组培苗和同品种扦插苗相比较，无论树形、叶片形状、大小、浆果各形态指标、色泽、品质、种子特征等植物学性状、物候期、抗病性、抗寒性、酒质等均未出现明显变异。组培苗定植当年田间长势比扦插苗弱，但根系分布较深，晚开花结果一年。组培树不含有扇叶和卷叶病毒，群体无性系植株生长比较整齐一致，群体产量提高４．６２－７．３８％；“左山一”组培苗，具有良好的遗传性状和生产性能。
1989-1995 years experiments show that: planting “Zuoyi a” tip 6-7 generation of tissue culture and cutting the seedlings compared with the same, regardless of tree shape, leaf shape, size, berry morphological indicators, color, quality, seed characteristics Other botanical traits such as phenology, disease resistance, cold resistance, wine quality did not show significant variation. Tissue culture seedling planting field growth than the cutting seedlings weak, but the root distribution is deep, the late blooming year. Tissue culture tree does not contain leaves and leafroll virus, clonal plant population growth more neatly, the population increased 4.62-7.38%; “Zusanli” tissue culture seedlings, with good genetic traits and production performance .
