乳酸鈣葉面施肥對絲瓜葉片礦物元素濃度之影響

Abstract

'七美'絲瓜利用不同濃度乳酸鈣葉面施肥後，主蔓與側蔓上的葉片中，以噴施0.05M乳酸鈣者有較高的鈣濃度，且可轉運至較頂端葉位之葉片;進一步在0.O5M乳酸鈣添加Break-Thru(界面活性劑)噴施葉面後，可增進乳酸鈣之吸收轉運效率，並防止葉面發生鈣之沉澱反應。‘Chi Mei'luffa after foliar spraying with 50mM calcium lactate had higher Ca concentrations in leaves of the main and branch stems than the rest of the leaves. In the meantime, calcium lactate plus surfactant ‘Break-Thru'application to leaves increased calcium absorption and transportation in the ‘Chi Mei'luffa plants
