Abstract: | The effect of different growth substances on the development of normal and abnormal stomata are presented. Anomocytic, paracytic,
anisocytic and stoma with a single subsidiary cell are observed. Abnormal developments like persistent stomatal cells, degeneration
of guard cells, unusual thickening, unequal guard cells, single guard cells and size and shape of the pore are noticed in
various growth substances. The growth substances also affect the stomatal frequency, stomatal index, epidermal frequency and
size of guard and epidermal cells in both the plants. The highest meristematic activity is found in MOR 100 ppm in brinjal
and in GA 25 ppm in tomato. The largest size of stomata is found in COL 25 ppm in brinjal and in MH 50 ppm in tomato. The
same growth substance responds differently in the two plants. |
