影響熱帶地區綠蘆筍品質之因子研究(一) 植物生長調節劑處理試驗(第一年)

Abstract

1.以植物生長抑制劑 Alar、Ethrel 及 N. A. A. 等不同濃度噴佈蘆筍植株，探討其對蘆筍嫩莖之影響。2. Alar 促使植株矮化及分株，高濃度時使嫩莖彎曲；Ethrel 促進蘆筍開花，並促使嫩莖提早開芒；N. A. A. 則使莖變為纖細。3.各處理對產量無顯著差異。 Different concentration of plant regulators of Alar, Ethrel, and NAA were sprayed on asparagus plant for studying their affect on the spear of asparagus. The results showed that Alar retarded the growth of plant and put forth plant branches. The spear sere somewhat curvature after Alar treatment. Ethrel promoted flowering of asparagus plant and caused loose head of spear NAA caused curvature and slimness of spear. But the yield of spear was no significant differences.
