Response of Vegetative Growth and Some Chemical Constituents of Syngonium podophyllum L. To Foliar Application of Thiamine, Ascorbic Acid, and Kinetin at Nubaria

Pot experiment was carried out in two seasons (2005 and 2006) at National Research Centre, Dokki, Cairo, Egypt, Research and Production Station, Nubaria. To study the effect of foliar application of thiamine (50, 100 ppm), ascorbic acid (50, 100 ppm) and kinetin (20, 40 ppm) in addition to untreated plants as control on vegetative growth and some chemical constituents of Syngonium podophyllum L. plants. Foliar application of all treatments significantly promoted all growth parameters compared untreated plants. Foliar application of 50 ppm thiamine, 100 ppm ascorbic acid and 40 ppm kinetin to syngonium plants significantly promoted plant height, number of leaves, stem diameter, leaf area, fresh and dry weights of plant, as well as chemical constituents, than that other treatments. The highest values were obtained in plants treated with 100 ppm ascorbic acid, 50 ppm thiamine and 40 ppm kinetin, respectively. Foliar application of the mentioned treatments to syngonium plant gave the highest levels of photosynthetic pigments, total carbohydrate content. Ascorbic acid at 100 ppm was the most effective treatment in increasing nitrogen, phosphours and potassium contents of the plants, followed by the treatment of 50 ppm thiamine. Foliar application of kinetin (20 and 40 ppm) resulted in the lowest nitrogen content compared with other treatments. On the other hand, kinetin (20 and 40 ppm) increased phosphorus and potassium contents than that of untreated plants.
