 note = {This report is a preliminary study to clarify the effects of exogenous brassinolide (BL) on the stem tissue growth of water spinach. Local varieties in Taiwan were used for the indoor experiments. The clones were propagated and grown under fluorescent lamps for plant growth, and the clones with 5 leaves were cut off and grown in a water culture for 7 days. Distilled water was used for diluting the concentration of BL, and the BL concentrations used were 0, 1, 2.5, 5, and 10 ppb (w/v). Each clone was cultured in 80 ml of the water solution. The plant height and stem diameter at the centre of the first internode above the point of cutting were measured after 5 days of treatment. The stem diameter and pith thickness increased significantly as the BL concentration in the water culture increased, whereas the cortex thickness was not affected by the BL concentration. The cavity diameters in the 5 and 10 ppb plots were significantly larger than those in the other plots. There was no significant difference in plant height among the treatments, although the plant height tended to be higher with increasing BL concentration., Article, 信州大学農学部AFC報告 11（1-2）: 1-4(2013)},
