Abstract

The morphological features are the basis of taxonomic identification of Mulberry species. The leaf morphology and venation pattern have been described in 4 Indian Mulberry species i.e., M. indica, M. alba, M. laevigata and M. serrata of the family Moraceae. The median strand joined and formed the mid rib, which extends into secondary in the opposite of both sides of lamina. The veins turned into a dense reticulum. The overall venation is reticulate with marked diversity in the mode of ramification. The development of areole showed variation in different species. The leaf size of Morus species varied and a wide range i.e., M. indica (120.00–234.00 cm²), M. alba (168.00–253.00 cm²), M. laevigata (204.00–480.00 cm²) and M. serrata (168.00–272.00 cm²). Number of strands ending into petiole is more or less similar in all species, which ranges from 3–5 but the venation pattern is thick in case of M. laevigata and M. serrata. The areole number/mm² varies from 1.54–5.20 and areole size from 0.18–0.65/mm² in different species. The areole number is higher in M. laevigata and M. serrata and lower in M. indica and M. alba. The leaf morphological characters, the foliar venation pattern, areole formation, number of veins ending into petiole and veins/areole are the important features for identification of different Morus species at the vegetative stage. The minor venation, which ramifies into lamina also indicates the leaf quality i.e., palatability to silkworm.
