The effects of salicylic acid (SA) and Putrescine (Put), on cut Narcissus was studied. SA (0, 100 and 200 mg l-1) and Put (0, 150 and 300 mg l-1), their combinations were tested as preservative mixture. This study was conducted in a factorial experiment with complete randomized design on 108 Narcissus cut flowers in horticulture laboratory of agriculture faculty of Islamic...

The nucleotide sequence (5966 nucleotides) of cDNA clones of strawberry mild yellow edge-associated potexvirus was determined. The genome contains six open reading frames (ORFs) encoding putative proteins with Mrs of 149,423, 25,344, 11,576, 8079, 25,714 and 11,216. In the first three putative proteins and the coat protein considerable similarity was found to comparable polypeptides of the pote...

A comparative study of the lectins from the families Amaryllidaceae and Alliaceae reveals many common features: all bind D-mannose exclusively and have similar molecular structures and amino acid compositions. All these lectins contain subunits of M, 11500-14000 which are not linked by disulphide bonds and occur as dimers (in Allium sativum, A. vineale, A. ursinum, A. moly, Narcissus pseudonarc...

The genus Narcissus belongs to the family Amaryllidaceae. This has been subject of numerous cytological and cytometric studies have shown enormous variation in terms genome size, ploidy level, even basic chromosome number. numbers are 5 or 7, but 10, 11, 12 recorded as well. Most narcissus cultivars euploid tetraploids. There also triploids. Some aneuploid such tetraploids triploids, with missi...

Antimicrobial activity and cytotoxicity of fifty one extracts of different parts of 14 plants were studied. Ethanol, methanol, aqueous, butanol, and n-hexane extracts were tested against three gram negative, two gram positive bacteria, and two fungi. Cytotoxicity and phytochemical screening were determined using MTT and TLC assays, respectively. Of the fifty one extracts, twenty two showed acti...
