    STATISTICAL COMPARATIVE PETIOL ANATOMY OF Salvia SP.
    Özdemir, A; Özdemir, AY; Yetisen, K
    In this study, petiol anatomy of 17 Salvia sp. taxa were compared statistically. In all the studied taxa, some differences were found in the petiole shape, number of vascular bundles and the presence of chlorenchyma. Anatomical variations in 17 Salvia taxa have been investigated by means of numerical methods (Analysis of variance and Pearson correlation). By the analysis of the investigated taxa from 17 leaf anatomy related characters, it has been determined that epidermis width and trachea diameter are the best character pairs which represent the variations in them. It has been also found that the results from numerical analysis of the leaf anatomy characters can provide additional evidences that correspond to the anatomy for the recognition of the taxa.

    RESPONSE OF CROCUS L. (IRIDACEAE) TO ECOLOGICAL CHARACTERISTICS
    Özdemir, A; Akyol, Y; Özdemir, AY; Özdeimir, C
    Three subspecies of Crocus specious (subsp. speciosus, subsp. ilgazensis, subsp. xantholaimos) two of them being endemics Blacksea region) were investigated for ecological characteristics. It has been observed that these subspecies usually prefer the soil which is acidic and has no salt in it. No statistical difference in per cent N and P was observed in all the three subspecies except in per cent K.
