不同海拔與採收期對本省柴胡性狀、產量與成分之影響

Abstract

不同海拔（85、550及850m）對於兩種省產柴胡之株高、葉重、根長、根徑及根重之影響很大，較高海拔(850m)對於柴胡葉重及根長之生育較為有利，較低海拔(85m)對株高、根徑及根重之生長促進效果較佳，惟其田間存活率較低。兩種柴胡於不同採收期（定植後3月、6月及10月）之性狀與收量之表現有很大差異，除了株高及根重外，皆以六月生者較佳。Experimental data of two Bupleurum spp. at three elevations showed that higher elevation (850m) was in favor of the development of leaf weight and root length. On the other hand, low elevation (85m) was beneficial for plant height, root diameter and root weight, however, its field survival rate was less than that of higher elevation. The field results also indicated that all agronomic characters and yield of the six-month old plants after transplanting was superior to those of the three- and ten-month old paints, except plant height and root weight.
