Abstract
|
|
|
|
Concentration of nutrient solution that can prevent blossom-end rot, and the characteristics of cuticular transpiration and Ca content at blossom-end rot occurrence were studied. Even at higher concentration of EC 12mS·㎝, suitable for production of high quality tomatoes, air flow to fruity accelerated the cuticular transpiration, and consequently prevented blossom-end rot. Cuticular transpiration rate increased with the incidence of blossom-end rot, but Ca concentration was constant. Air flow was more effective at lower EC. Intense light caused severe water stress at 12mS·㎝ with only one third of the leaf transpiration rate at EC4mS·㎝.
