摘要: Performance of ‘Known-You 301' tomato plants on two rootstocks(Solanum melongena L. cv. ‘EG203' and ‘VF') was evaluated in a close hydroponic system under combined Ca2+ stress. Before grafting, the rootstock of ‘VF' eggplant had a better ability to absorb Ca2+ when cultivated both in normal condition (5000 μM Ca2+) and in stress condition (143μM Ca2+) than ‘EG203' eggplant, but there are not significantly different in Ca2+ transportation form root to shoots between ‘VF' and ‘EG203'. As hydroponic system, better ability and growth rate of ‘VF' than ‘EG203' in soil-pot system. However, according to dry and fresh weight, growth of ‘Known-You 301' on ‘VF' was considerable better than on ‘EG203' at 143 μM Ca2+, but the Ca2+ content in shoot of grafted ‘Known-You 301' on ‘EG203' was higher than on ‘VF' under Ca2+ stress. The calcium content of fruit of grafted ‘Known-You 301' on ‘VF' was higher than on ‘EG203'. Our study demonstrated that eggplant rootstock can affect the absorption of Ca2+, but can't affect the transportation of Ca2+ from root to shoot.
水耕栽培茄子'VF'在正常(50OOμM)或缺鈣(143μM)逆境栽培下,其根部對鈣之吸收能力較'EG203'高,但轉運至上位葉之能力與'EG203'並無顯著差異。盆栽土耕栽培亦以'VF'茄子對鈣之吸收能力較佳,且以'VF'茄子生長勢優於'EG203'。'農友301'嫁接'VF'之組合生長勢優於嫁接'EG203'之組合,缺鈣逆境下其乾鮮重亦高於嫁接EG203'之組合,根部吸收鈣能力VF高於'EG203',而上位葉及新梢之鈣濃度在極度缺鈣逆境處理下則以嫁接在'EG203'鈣濃度較嫁接'VF'高。果實鈣濃度則以嫁接'VF'砧木較'EG203'高。綜合上述結果,'VF'茄子根部具較佳吸收鈣之能力,而'農友301'番茄嫁接在'VF茄子砧木其根部鈣濃度較高.但轉運至新葉或新梢則與嫁接在'EG203'茄子砧木無顯著差異。
