Additionally, the water fraction from wood extract can inhibit the root growth on Pak-choi. At 1000 μg/mL, after 72 h, the length ratio of root to shoot was 0.69, and the dry weight of Pak-choi root was only the 20.6% of control. But the extracts of Sapindus mukorossi have no influence on the growth of Pak-choi with normal growth 7 days.
此外，木材抽出物之水分离部则具有抑制胚根生长的作用，经浓度1，000 μg/mL处理72 h之小白菜，胚根与胚茎长比值为0.69，且其胚根乾重仅为对照组的20.6%，但无患子抽出物对正常生长7天后之小白菜并无显著抑制生长作用。

These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.
