Abstract

Ten large flowered chrysanthemum cultivars, viz., 'Beat Rice May', 'Beauty', 'Casa Grande', 'Jet Snow', 'John Weber' , 'Miss Maud Jeffries', 'Penny Lane', 'Shanker Dayal', 'Snow Ball' and 'S.S. Arnold' from National Botanical Research Institute (NBRI), Lucknow, were evaluated for morphological and biochemical characterization. Morphological data were recorded on vegetative and floral characters. Biochemical characterization included analysis of anthocyanins, carotenoides, chlorophyll content (chlorophyll a, b and total) and flavonoids. Results on morphological and biochemical parameters clearly indicated distinctness among cultivars with reference to differences in morphological characters and chemical composition of pigments.

Keywords

Abstract

Influence of different growth regulators was studied on in vitro growth and regeneration of tomato (Solanum esculentum) explants derived from hypocotyls and cotyledons of aseptically grown seedlings. On the basis of regeneration frequency, number of shoot primordia and shoots produced per explants, it is concluded that the best regeneration is achieved on Murashige and Skoog (MS) medium supplemented with 0.5 mg L"¹ of indole-3-acetic acid and 1.0 mg L"¹ zeatin. In all the genotypes studied, a good percentage of regeneration frequency was observed in hypocotyl explants used.

Keywords
