Minor morphological differences between the Atlantic and Mediterranean populations of Pomatoschistus pictus (Malm, 1865) resulted in the description of two subspecies of this species by Miller (1973): Pomatoschistus pictus pictus and P. p. adriaticus. However, the similarity of morphometric and meristic characteristics led to an ambiguity about their status. Despite high morphological similarities ...

Abstract:
... In the present report the effects of naphthalene acetic acid (NAA), gibberellic acid (GA3), and epibrassinolide (EBr) on in vitro pollen germination of three Vitis vinifera L. cultivars were described. The basic media contained 1% agar and 20% sucrose. Pollen germination of cultivar 'Amasya Beyazı' was not affected by the treatments and the germination rate varied between 6.16% (1.0 mg L-1 NAA) an ...
