Abstract

Tree-spray of liquid calcium compounds extracted from oyster shell significantly increased the calcium contents of ‘Jingfen’ pear fruits. The spray of calcium chloride was also effective on the increase of calcium content in leaves and fruit flesh, but not in fruit peel tissue. The levels of fruit and shoot growth, and the contents of soluble solids and vitamin C were higher in liquid calcium spray treatment. However, the acidity of fruit was not affected. Tree-spray of liquid calcium compounds effectively decreased the occurrence of calcium deficiency in fruit. Electron microscopic study revealed the high integrity of middle lamella of liquid calcium treated fruit compared with that of untreated ones.

배 금풍 품종에 대한 액상칼슘화합물의 수관살포는 잎과 과피 및 과육에서 칼슘 축적량을 현저히 증가시켰다. 염화칼슘을 수관살포한 경우 잎과 과육에서는 액상칼슘화합물 처리에서와 비슷하게 칼슘을 축적시켰으나, 과피에서는 액상칼슘화합물을 처리한 경우 칼슘 축척량이 훨씬 많았다. 액상칼슘화합물 수관살포는 수확시 신초장, 과중, 가용성고형물, 비타민-C 함량을 증가시켰으나, 산함량은 큰 차이가 없었다. 칼슘결핍과 발생율은 액상칼슘화합물 수관살포로 현저히 줄일 수 있었다. 수확시에 과육의 세포조직을 관찰한 결과, 액상칼슘화합물 처리과에서는 중층의 용해정도가 물 처리과에 비하여 줄어 들었다.
