摘要：

The effects of jasmonic acid (JA) on flowering in the photoperiodically neutral plant, Spirodela polyrrhiza, were investigated. Sterilized isolated plants were grown axenically in modified Pirson-Seidel nutrient medium with Heller microelemental nutrient solution, illuminated by 3000 +/- 100 lx from 6 gro-lux fluorescent tubes (Sylvania 40W/220V). The temperature was kept constant (301 +/- 1K). Under long-day (LD) and short-day (SD) conditions, JA (0.475 -47.5 nmol . L(-1)) enhances flowering in Spirodela polyrrhiza. Under the same conditions, at a concentration of 237.5 nmol . L(-1), JA inhibits flowering, and at a concentration of 475 nmol . L(-1) it blocks (prevents) flowering.
