The changes in the contents of free and bound gibberellin-like activity (GA) of Tulipa gesneriana L. cv. Ralph during development under 2 temperature conditions were studied. The results show that the content of free GA of bulbs grown at 18 degrees increased by 67% over the initial level during development. The bound GA showed a slight initial increase and was followed by a rapid decrease. In c...

This paper reports on a Lexicalised Tree Adjoining Grammar for Polish, extracted automatically from the Polish constituency treebank. The grammar consists of 23 570 elementary trees anchored by 11 515 lexemes. Running the grammar on the sentences from the treebank using a modified version of TuLiPA parser showed that it achieves a high accordance (almost 99%) with the treebank annotation – in t...

Seeds are important for the preservation and reproduction of wild tulips in situ, but only a few studies have been carried out on their seed morphology germination characteristics. In this study, eight tulip species native to China were used. Their superficial ornamentation, relationship between germination, effects manipulating incubation temperature, coat, gibberellin (GA3) application studie...

Climate fluctuations in the Quaternary period significantly influenced evolution and distribution of plants, which caused to a serious genetic effects speciation activity [1]. Thus, Central Asia is distinguished by wide variety flora, including 9520 species, while 20% are endemics [2]. Great phenotypic diversity wild flora Uzbekistan, numbering about 4400 species vascular plants determined pecu...

Cytochrome P-450 and NADPH: cytochrome P-450 reductase were solubilized by detergents from microsomal fraction of tulip bulbs Tulipa fosteriana L. and purified to electrophoretic homogeneity. The purification was achieved by anion-exchange column chromatography, hydroxyapatite-column chromatography and affinity chromatography. The two enzyme showed relative molecular weights of about 54,200 and...
