Abstract
Response of Egyptian clover plants to N-fertilization and/or application of IAA or kinetin was studied. Application of either N, IAA, or kinetin and the combination between N and each of IAA and kinetin enhanced growth of plants with a maximum green yield obtained from N-fertilized plants treated with kinetin at 30 mg/l. In addition, N fertilization and IAA as well as kinetin application stimulated greening of the treated plants through enhancing chlorophyll content.
N-fertilization increased the nutritional value of the shoots through increasing N and P contents in both leaves and stems. The effects of IAA and kinetin on N and P contents were variable and prominent in the stem rather than the leaf, and the most favorable effect was recorded in case of kinetin at 30 mg/l. The highest N content in the stem was obtained in N-fertilized plants treated with the above mentioned level of kinetin.
Plants showed the best growth enhancement were subjected to certain anatomical measurements. Anatomical study revealed that growth stimulation due to IAA at 100 mg/l and kinetin at 30 mg/l was, anatomically, based on increasing no. of vascular bundles, dimensions of the bundle, and no. of xylem vessels/bundle, as well as, increasing cortex thickness
