| Tomato (Lycopersicon esculentum M. cv. ¡®Momotarou¡¯) and hot pepper seedlings (Capsicum annuum L. cv. 'Nockkwang')were grown under the 24h photopeliod (12 hrs light period: 12 hrs dark period) and 6 h photoperiod (3 hrs light period: 3hrs dark period). As a result of this experiment, the following details were observed. Plant height, leaf area, total dry weight, and leaf chlorophyll content decreased in case of tomato seedlings when they were given 6 h photoperiod. But the same effect was not observed in case of hot pepper seedlings. The photoperiod, however, did not produce any significant effect on the uptake of N, P, K, Mg and Ca ions in their nutrient solutions with the exception of their Fe. On thc 10th day of treatment, leaf chlorosis started to become visible in tomato seedlings and at the same time the uptake of Fe went down when the 6h photoperiod was applied to both tomato and hot pepper scedlings. In addition to this phenomenon, the sucrose content in leaf increased in case of tomato plants which were treated with 6 h photoperiod; on the other hand, their glucose content was observed to have decreased. |
