Abstract
The effects of calcium on growth and chilling resistance of grafted and self- rooted eggplant seedlings was studied in a hydroponic culture system.
Under the calcium-deficient treatment, growth of seedlings was seriously inhibited.
Chilling- induced total soluble protein, boiling stable proteins, soluble sugars, soluble calcium and total calcium all increased with calcium application and grafting.
This study suggests higher carbohydrate content of grafted seedlings might be caused by variation in cellular calcium levels.
The variation of calcium content was potentially the main reason that grafted seedlings had higher chilling resistance than self-rooted seedlings.
Calcium appears to play an important role in increasing carbohydrate content and enhancing chilling resistance.
