Effect of different growth substances on the foliar stomata of Tagetes erecta L

Abstract

The response of abaxial and adaxial stomata to various growth substances were examined in leaves of Tagetes erecta L. From stomatal studies it is clear that growth substances produced several variations in the morphology of stomata. The anomalies recorded include persistent stomatal initial, loss of one or both guard cells in a significant percentage of stomata, contiguous stomata, cytoplasmic connections, one and a half contiguous stomata etc. Significant changes in frequency of epidermal cells and stomata, size of epidermal cells and stomata and stomatal index were noticed in various treatments.
