Production of tomato is not only focused on the yield increase, but also on the quality improvement. Blossom end rot (BER) is a common physiological disorder of tomato encountered during commercial production, and often causes a reduction in yield and quality. The occurrence of BER may be due to the interference of the uptake, translocation and partitioning of calcium within a plant which causes calcium deficient in the distal portion of fruit. In addition, it is known that transgenic tomato with high expression level of sCAX1 (small cation exchanger 1) may also lead to the occurrence of BER through the abnormal partitioning and distribution of calcium in a cell. Spraying calcium chloride (CaCl2) solution on plant, a common approach to counter the problem of BER, is not only time- and labor- consuming, but also poorly effective. Therefore, this research is intended to find out an alternative way to resolve the BER problem and further explore the physiological mechanisms of BER by investigating the effect of applying different combination of mineral elements in diverse manners. For above purposes, the following studies will be taken. (1) Screening BER- sensitivity and -insensitivity cultivar. (2) Effects of calcium and other mineral elements on the improvement of BER. (3) Effects of different applied methods of mineral elements on the improvement of BER. (4) Effects of different mineral elements and applied methods on the yield and quality of tomato fruit. (5) Physiological mechanisms of tomato BER.番茄尻腐病鈣tomatoblossom end rotcalcium
