The nutrient contents in leaves from different kinds of shoots were analyzed (Table 1). Nutrient contents of K, Mg and N were in the optimum ranges in 4 kinds of shoots, but P content showed overdose in all shoots. The Ca content revealed inadequate and differentiated the most among 4 kinds of shoots. Comparing to the pear fertilization suggestion (Lo, 2005), Ca content of lateral shoot leaves and water sprout leaves were about 35-40% less than the optimum content, and the contents of fruiting and non-fruiting spur leaves were at the minimum level of the optimum range. The results revealed that the Ca deficiency occurred only in some, but not all orchards in this study. This also meant that the fruits in this research were from both the nutrition deficiency and optimum orchards. This condition provided the sufficient data to understand the relationships between the internal browning severity level and the nutritional content of the trees.
