摘要: Floral induction in longan (Dimocarpus Lour.) trees by potassium chlorate (KClO3) treatment or low temperature (LT), is partially acted their interference with the hormonal concentration. Therefore, effect of KClO3 and LT on cytokinins (CKs) concentration was investigated these experiments. The experiment performed 4 years old cv. Daw. completely randomized design 7 replications (of each 1 tree) 3 treatments were namely 1) control, 2) 400 ppm 3) (day 17 C night 12 C). Cytokinins examined competitive enzyme-linked immunosorbent assay (ELISA) apical buds, leaf roots: trans-zeatin/zeatin riboside (tZ/ZR) isopentenyl-adenine/isopentenyl-adenosine (iP/iPA) during period. results showed that applying at lead to floral bud initiations faster than maintaining However control did not show flowering. content alterations both iP/iPA tZ/ZR all tissues enhanced until prior flowering chlorate, compared treatment.
