以南通小方柿（ＤｉｏｓｐｒｕｓｋａｋｉＬｉｎｎ．ｃｖ．Ｎａｎｔｏｎｇｘｉａｏｆａｎｇｓｈｉ，以下简称小方柿）为试材，并以大方柿、朱砂红作对照，对小方柿的树体特征以及某些生理生化特性进行了分析。结果表明，小方柿的树高、冠径、新梢长度、粗长比以及节间长度均显著地小于同龄大方柿和朱砂红；小方柿的枝皮率和叶片栅栏组织与海绵组织之比高于其他两品种，表现出明显的矮生树结构特性；茎尖及叶片的过氧化物酶（ＰＯＸ）活性与树体生长势呈显著的负相关；内源生长素（ＩＡＡ）、赤霉素（ＧＡ１＋３）与树高呈显著的正相关；内源脱落酸（ＡＢＡ）与树高呈显著的负相关，其中以果实成熟期叶片ＡＢＡ含量与树高相关程度最显著（ｒ＝－０．９６９７＊＊）。
Taking Nantong Xiaopu persimmon (DiospruskakiLinn.cv.Nantongxiaofangshi, hereinafter referred to as Xiaopu persimmon) as the test material, the tree body characteristics and some physiological and biochemical characteristics of Xiaopu persimmon were analyzed with the comparison of the persimmon and vermilion red. The results showed that the tree height, crown diameter, shoot length, length to length ratio and internode length were significantly smaller than those of the same age, persimmon and cinnabar; the shoot bark rate and leaf palisade tissue and spongy tissue Compared with the other two cultivars, the structural characteristics of dwarf trees were obvious. The activity of peroxidase (POX) in shoot tips and leaves was significantly negatively correlated with the growth of the tree. The contents of IAA, There was a significant positive correlation between GA1 + 3 and tree height. There was a significant negative correlation between ABA and tree height, and the most significant correlation was ABA content with tree height at fruit maturity (r = -0 .9697 **).
