      More Details Abstract Fulltext PDF

      The response of abaxial and adaxial stomata to various growth substances were examined in leaves ofTagetes 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.

      Various types of stomatal abnormalities like persistent stomatal initials, single guard cells, degenerated guard cells and contiguous stomata with contiguity in different directions were recorded due to the treatment of different growth substances. Growth substances also altered the stomatal size, epidermal cell size, stomatal frequency, index and length-to-breadth ratio. It seems that the effect of these substances starts from the stomatal ontogeny and continue up to the last phase of development leading to such variations.
