研究了种植前土壤施壳聚糖对萝卜根茎组幼苗顶部和根系生长的影响。施用0.1%壳聚糖可使玉米叶面积和顶干重增加，是施用0.5%和1%壳聚糖的对照的两倍。壳聚糖对叶片生长的促进作用大于子叶的促进作用。壳聚糖对丝状根的长度和一级侧根的数量没有影响，但对从一级侧根分支出来的一级侧根和二级侧根的数量有显著的增加。根毛的长度和密度是可变的，壳聚糖使侧根的长度和密度增加。
The effects of chitosan application to soil before planting, on the growth of the tops and roots of the seedlings of radish, Raphanus sativus L., radicula group, were investigated. Leaf area and top dry weight of the crop were increased by application of 0.1% chitosan, and were twice as much as those in the untreated-control by application of 0.5% or 1%. Chitosan application promoted the growth of foliage leaves more than that of cotyledons. The lengh of tap roots and the number of first order lateral roots were not affected, but the numbers of first order lateral roots and second order lateral roots which branched from the first ones were increased markedly by chitosan application. The length and density of root hairs were variable, and those of lateral roots were increased by chitosan application.
