Abstract
|
|
|
|
This study was conducted to investigate the effects of uniconazole (Sumiseven), an existing expensive growth retardant, and diniconazole (Binnari), used as a cheap germicide, on the growth and flowering of Vinca major and Salvia splendis for the possibility of substitution for expensive growth retardants. The growths of V. major and S. splendis were retarded by Binnari treatment. The effect of Binnari 100 ㎎/ℓ treatment was higher than that of Sumiseven 5 ㎎/ℓ treatment in both plants. The length of leaves was remarkably retarded by Binnari treatment, however, the width of leaves was only slightly retarded, giving the leaf a round shape. The number of days to flowering was increased by Binnari treatment in both in V. major and S. splendis. The number of days to flowering in V. major showed no significant difference compared to the control except by treatemtn with Binnari 400 ㎎/ℓ. The number of florets of S. splendis increased with treatment with Binnari 100 and 200 ㎎/ℓ.
