甜椒幼苗喷施三十烷醇,其平均叶数、株高以及地上部干重均比对照显著增加。以浓度10~(-2)ppm乳剂喷施较好,地上干重可比对照提高37.4％,但对增加根干重作用不明显。大田芹菜应用三十烷醇,其平均株高可较对照增加2.1—9.5厘米,有促进芹菜延伸生长的功能;大田甜椒喷施,可提早开花,但植株生长差异不大。两种蔬菜在大田喷洒三十烷醇产量均无明显增加。 Treating sweet pepper seedlings with triacontanol, the average number of leaves, plant height and above-ground dry weight were significantly increased. Spraying at the concentration of 10 ~ (-2) ppm emulsion was better, and the dry weight on the ground could be increased by 37.4% compared with the control, but the effect of increasing root dry weight was not obvious. Celery application triacontanol, the average height can be increased 2.1-9.5 cm compared with the control, to promote the extension of celery function; field pepper spraying, early flowering, but little difference in plant growth. There was no significant increase in the production of triacontanol between the two vegetables in the field.
