| 摘 要： | 对多年观测的榨汁加工型非结球芽甘蓝生物学特性进行了动态分析，结果发现：不同品种非结球芽甘蓝株高在不同时期具有不同的生长速度，但大致分为4个阶段，即株高缓慢生长期（9月17日—10月17日），株高生长高峰期（10月18日—30日），株高相对缓慢生长期（10月31日—11月16日），株高生长次高峰期（11月17日后）；叶片日生长变化大致出现3个阶段，即缓慢增加期、高峰期、又进入缓慢增加期；叶展度生长呈现抛物线生长趋势，即高峰期比较明显，均在10月1日—17日之间；叶片长度大致出现3个阶段，即较快生长期（9月17日—10月17日），缓慢生长期（10月18日—11月16日），又进入较快生长期（11月17日以后），但波峰起伏不大；叶宽的生长变化比较复杂，叶宽增加期主要在前期（9月17日—10月17日），后期叶宽增加减慢，在11月上旬几乎停止生长，11月下旬起叶宽又有所增加；所有品种的茎粗生长，几乎都在9月中旬至10月底前完成，进入11月，茎粗似乎不再生长。最后对当前3个主要推广品种的生物学特性进行了描述，以填补国内空白。 |

| Abstract: | It was studied on dynamics of biological characteristic in suitable processing juice for leaves of non-brussels sprouts (Brassica oleracea vat. Germmifera) by years of experimental observation. The result indicated showed that there were different growth rate for the plant height of different varieties of non-brussels sprouts at different times. There were mainly four phases in the plant growth, i.e. the first slow growing phase (September 17-October 17), the second quick growing fastigium (October 18-30), another slow growing phase (October 31-November 16) and secondary fastigium (November 17 future). There were approximately three growth periods in leaves growth, that is first slow increasing period, then inapparent wave crest and third slow increasing period. The growth of plant spread angle showed a parabola curve, i.e. the wave crest was obvious and mainly among October 1-17. There were three phases in growth of the leaves length, that was faster growing period (September 17-October 17), slower growing period (October 18-November 16) and another faster growing period (November 17 onwards), the both undulation were unconspicuous. Increasing of leaf width was quite complex. Growing of leaf width was mainly in the earlier period (September 17-October 17). It was slower in the later period until stopped growing in the first ten days of November. Growing of leaf was increased a little. All varieties of stem diameter growth was almost finished in the mid-September to the end of October. It was no longer growth by entering November. Biological characteristics of three main varieties was described to fill the domestic blank in the end. |
