Abstract
甘藍(cabbage; Brassica oleracea L. var capitata) 為綠植株春化型(Green plant vernalization type)植物，需春化處理來誘導開花。本試驗之目的為研究根砧種類與品種對甘藍嫁接苗開花之影響。接穗使用‘初秋’甘藍，根砧包含芥藍、油菜、芥菜、結球白菜、青花菜、花椰菜、甘藍，結果以芥藍根砧具有最高嫁接存活率。嫁接試驗材料種植於國立臺灣大學生物資源暨農學院附設農業試驗場園藝分場(平地)及國立臺灣大學生物資源暨農學院附設山地實驗農場(高地)。於平地，所有嫁接組合開花率皆為0%；於高地雖部分嫁接組合開花率略優於‘初秋’未嫁接組(50.00%)，但最高僅能達57.14%，且顯花天數皆與未嫁接對照組無顯著差異，此結果說明利用嫁接方式促進‘初秋’甘藍開花之程度有限。
Cabbage (Brassica oleracea L. var. capitate) is a green plant-vernalization-responsive-type plant, which requires vernalization to induce flowering. This research aimed to study the effects of species and variety of rootstocks on the flowering of the grafted cabbages. In this research, 'K-Y cross' cabbage was used as scion for the grafted cabbage, while the rootstocks were selected from Chinese kale, rape, leaf mustard, Chinese cabbage, broccoli, cauliflower and cabbage. The results show that the grafted cabbage with Chinese kale as rootstock had the highest survival rate. Grafted plants were separately grown in the Experimental Farm, College of Bioresources and Agriculture, National Taiwan University (as a lowland treatment) and Highland Experimental Farm, College of Bioresources and Agriculture, National Taiwan University (as a highland treatment). The flowering rate of each of the grafting combinations in the lowland was 0%. In the highland, the flowering rates of some of the grafting combinations were slightly higher than those of the non-grafted control (50 %), but the highest one was only 57.14%. In addition, no significant difference in days to flowering was found between the grafting combinations and the non-grafted control. These results indicate that the range of the promotion of 'K-Y cross' cabbage flowering by grafting was limited.
