RESPONSE OF Chasmanthe aethiopica (L.) N.E.Br. PLANTS TO FOLIAR SPRAY WITH KINETIN AND KRISTALON
Propagation of Antholyza (Chasmanthe aethiopica (L.) N.E Br.) by seeds, usually needs 3-4 years to get flowering plants, and may be accompanied with some genetical isolations. However, in order to keep the quality and colour of the cultivated species, it is preferable to use new corms or cormels in propagation. Increasing such new corms or cormels on the mother plant is considered the main target from the commercial point of view.
So, a field trial was carried out at Orman Botanical Garden, Giza, Egypt during 2005-06 and 2006/07 seasons to study the effect of kinetin (6-furfuryl aminopurine) at the levels of 0, 25, 50 and 75 ppm, kristalon (a complete fertilizer of 19:19:19 + micronutrients) at the rates of 0, 1, 2 and 3 g/L and the combination between 50ppm kinetin and 2 g/L kristalon on the vegetative growth, flowering, corms productivity and chemical composition of Chasmanthe aethiopica (L.) N.E. Br. Plants.
The obtained results indicated that all treatments, except for 1 and 3 g/L kristalon, improved plant height and fresh and dry weights of leaves, with the superiority of the combined treatment which significantly gave the longest plants and the heaviest fresh and dry weights. Number of leaves/plant, however was not affected by either treatments used in such study. The best flowering precocity and quality of spikes (assessed as flowering stalk length, No. florets/ spike and vase life) were found to be the best in case of the combined treatment, which also gave the highest number and best quality of cormels/ plant, the highest content of pigments in the leaves (specially chlorophylls a and b), the best balance between promoters (as indoles) and inhibitors (as phenols), as well as the percentage of total carbohydrates, N, P and K in the leaves and corms of treated plants.
Hence, it is recommended to spray the foliage of Chasmanthe aethiopica (L.) N.E. Br. plant till run off with the combination of 50ppm kinetin and 2 g/L kristalon after planting the corms by about 50 days, thrice with three weeks interval for best growth, flowering, corms productivity and chemical composition.
