摘要

The objects of this experiment were to investigate the influences of the crown size of plantletss of Fragaria×ananassa Duch. cv. 'TY. No.1' on plant growths and fruit yields, and to investigate the influences of leaf numbers of plants on fruit yields too. These plantletss were classified into 4 classes of A (A＜6 mm)、B (6≦B＜9 mm)、C (9≦C＜12 mm)及D (D≧12 mm) according to their crown diameters. The larger the crown size the larger the leaf area within 120 days after planting, and the larger the canopy within 60 days after planting. The early harvest yields yield from crown size less 6 mm was significantly less than others. The later yields from various classes were between 109.76 and127.5 g/plant, and had insignificantly different. The total yield of C class was the highest one of 215.6 g/plant, of B class was the second rank of 198.4 g/plant, Both D and A classes were 100.5 and 96.2 g/plant, respectively. It were concluded that the crown sizes of B (6≦B＜9 mm) and C (9≦C＜12 mm) classes were recommeded to be planted in Taiwan. After 3 months of planting, part of plant leaves were removed per week to keep 6, 10, 14, 18 and 22 leaves/plant, that were 87.4, 90.4, 100.3, 92.3 and 89.2 g/plant, respectively, and did insignificantly different at the early harvest, these treatment of 6 and 10 leaves produced less fruits than others, but did heavier fruit weight and rate of marketable fruits. The later harvest yields of 6, 10, 14, 18 and 22 leaves/plant treatments were 87.5, 141.0, 130.3, 147.6 and 139.3 g/plant, respectively. As well as, total yields were 174.9, 231.4, 230.6, 232.7 and 228.5 g/plant, respectively. Total yield and later yield of these treatments except of the 6 leaves treatment were insignificantly different. It were concluded that the plants keeping 10 leaves resulted to the best yield.
