Abstract
This study was carried out to examine the effects of foliar-sprayed diniconazole on the morphological characteristics and the contents of polyamines (PA) and proline, and to investigate their relationship with stress tolerance in Lilium davuricum native to Korea. Plants with 5 cm mean height were sprayed with 50 mg.L(-1)diniconazole or distilled water (control) and grown in a greenhouse maintained at 23/18 degrees C (day/night) for 30 days. Diniconazole decreased plant height, leaf length, diameter and length of the pith and cortical cell of the stem, while it increased the thickness and epicuticular wax of leaves measured at 30 days after treatment. In polyamines contents, diniconazole increased spermidine content at 5-10 days after treatment and spermine content after the 10th day of treatment as compared with the control. Diniconazole decreased proline content after the 10th day of treatment as compared with the control. From these results, it was concluded that foliar-sprayed diniconazole might morphologically and biochemically improve the stress tolerance of this plant species.
