چکیده
Background: Monovarietal cultivation of cotton plant allowed the genetic erosion for traditional varieties that proceed essential traits mainly involved in breeding. These need to be preserved future used. This study aims evaluate effect gibberellic acid on seed germination and Benzylaminopurin (BAP), Kinetin (KIN), α-naphthalene acetic (NAA) activated charcoal (CA) seedlings growth obtained from different type explants.
 Methodology: The seeds three improved (KET782, ANG956, OKP768) five local (Q62, Q64, Q85, Q88, Q92) were germinated with concentration (GA3). Different explants collected plantlets cultivated culture media containing plants regulators concentration.
 Results: We found Gibberellic Acid activity significantly varied according variety GA3 medium. 63.33% rate OKP768 was medium 0.5 mg/L while 1 mg/l gave highest Q85 (75%), Q64 (69.17%), ANG956 (40.83%). regeneration within 100%of axillary nodes regenerated Q62; Q92 60% zygotic embryos OKP768. Moreover, supplemented (1mg/l) + NAA (1 mg/l) induced greatest number roots (2.75 roots/plantlet) varieties. With (10 g/l), achieved better performance respective length average 3.4 cm/plantlet 2.1 cm/plantlet. at 10 g/l highly influenced an 7.7cm variety.
 Implication: protocol established during this will useful vitro conservation

Polyploidization Altered Gene Functions in Cotton (Gossypium spp.)
Cotton (Gossypium spp.) is an important crop plant that is widely grown to produce both natural textile fibers and cottonseed oil. Cotton fibers, the economically more important product of the cotton plant, are seed trichomes derived from individual cells of the epidermal layer of the seed coat. It has been known for a long time that large numbers of genes determine the development of cotton fi...

15 صفحه اولSurface plasmon resonance detection of transgenic Cry1Ac cotton ( Gossypium spp.).
The detection and identification of genetically modified (GM) plants are challenging issues that have arisen from the potential negative impacts of extensive cultivation of transgenic plants. The screening process is a long-term focus and needs specific detection strategies. Surface plasmon resonance (SPR) has been used to detect a variety of biomolecules including proteins and nucleic acids du...
متن کاملIntegrating Ex situ and In situ Conservation of Lemurs
Site-based and cross-regional habitat and species conservation e!orts in Madagascar, such as proposed in the previous chapters of this Lemur Conservation Strategy, should always be the main focus of lemur conservation. However, with many wild lemur populations rapidly declining and their habitat being lost at constantly high rates, captive assurance colonies are becoming increasingly important,...
