| Seedlings of ¡®Nokgwang¡¯ and ¡®Kwari¡¯ green pepper were cultured in 32-cell plug trays in TK$_2$ medium to find out optimal concentrations of phosphate. Seedling growth of both ¡®Nokgwang¡¯ and ¡®Kwari¡¯ cultivars was affected by phosphate strength. Applying P fertilizer to the plug system caused a marked increase in plant height and leaf area at 1.0 phosphate strength. On the other hand, total dry weight increased with increasing phosphate strength. Higher chlorophyll content was observed in ¡®Nokgwang¡¯ than ¡®Kwari¡¯ in all treatments. Phosphate strength greater than 0.5 gave similar chlorophyll content. Photosynthetic rate was higher for plants fertilized with 1.0 strength for ¡®Nokgwang¡¯ and 0.5 strength for ¡®Kwari¡¯than the other treatments. Higher concentrations of phosphate reduced photosynthesis in both cultivars. With ¡®Nokgwang¡¯increasing concentration of phosphate up to 1.0 strength resulted in increase in stomatal conductance and transpiration rate. |
