Abstract

An important characteristic of foliage plants is the production of enough lateral or basal shoots. Among the most commonly used branching-inducers are gibberellic acid (GA 3 ) and N 6 -benzyladenine (BA) which are synthetic cytokinins that have been shown to increase shoot number in some plant species. The aim of this research was studying the effects of synthetic branching agents on a foliage plant. The effects of GA 3 and BA on Ficus benjamina plant was evaluated under greenhouse condition. Plants were treated with foliar application of GA 3 and BA at 0, 100 and 200 mg L -1 . The plants that were treated with GA 3 and BA at 200 mg L -1 showed the highest number of leaves and plant height. Foliar application of 200 mg L -1 GA 3 + 200 mg L -1 BA increased photosynthetic pigments. The highest rate of soluble carbohydrates and reducing sugars were belonged to 200 mg L -1 GA 3 and 100 mg L -1 GA 3 + 200 mg L -1 BA, respectively. Results indicated that application of 200 mg l -1 of GA 3 + BA significantly promoted morphological growth, chlorophyll and carotenoid content, reduced sugars and soluble carbohydrates in F. benjamina .

赤霉素酸和苄基腺苷对榕树生长特性、糖和光合色素的影响。

叶片植物的一个重要特征是产生足够的侧枝或基枝。其中最常用的分枝诱导剂是赤霉素(ga3)和n6 -苄基腺嘌呤(BA)，它们是合成的细胞分裂素，在一些植物物种中已被证明可以增加芽数。本研究的目的是研究合成分枝剂对叶植物的影响。在温室条件下，评价了ga3和BA对榕树植株的影响。叶面施用GA 3和BA，浓度分别为0、100和200 mg L -1。ga3和BA浓度为200 mg L -1处理的植株叶片数和株高最高。叶面施用200 mg L -1 ga3 + 200 mg L -1 BA增加了光合色素。可溶性碳水化合物和还原糖的含量分别为200 mg L -1 ga3和100 mg L -1 ga3 + 200 mg L -1 BA。结果表明，施用200 mg l -1的GA 3 + BA显著促进了本杰明娜的形态生长、叶绿素和类胡萝卜素含量、还原糖和可溶性碳水化合物含量。
