چکیده

Cotyledonary nodes taken alongwith shoot apex from seedlings of cotton (G. hirsutum) proliferated into shoots on nutrient agar medium supplemented with cytokinins. In the presence of optimal plant growth regulators, low light intensity enhanced the number of shoots initiated per explant in cotton. An average of 33.5 +/- 2.9 shoots were obtained from a single explant cultured for 8 weeks which is about four fold higher than the values reported in earlier protocols. The isolated shoots were rooted on nutrient agar medium supplemented with alpha-naphthalene acetic acid and transferred to soil after acclimatization. Regenerated plants were morphologically identical to the seed-germinated plants and were fertile.

In vitro Plant Regeneration from the Callus of Shoot Tips in Cotton (Gossypium hirsutum L. cv. SVPR 2)

A high efficiency shoot organogenesis from callus cultures and plant establishment protocol has been developed for cotton (Gossypium hirsutum L. cv SVPR-2) through shoot tip. After 6 weeks of culture, green-compact-nodular organogenic callus induction was observed on the medium fortified with (MS) basal salts, B5 vitamins, 2.0 mgl-1 of benzylaminopurine (BAP), 1.0 mgl-1 kinetin (KN), 30 gl-1 gl...

Cotton (Gossypium hirsutum L.) is a source of edible oil and fatty acids (FAs). In this study, embryos’ explants were cultured in MS medium with different concentration of  plant growth regulators (phytohormones) include BA, IAA, IBA, 2, 4- D and NAA, to finding the relationship of hormone and organogenesis with oil and FAs content. Oil was extracted with chloroform and methanol. FAs o...

High-frequency regeneration via multiple shoot induction of an elite recalcitrant cotton (Gossypium hirsutum L. cv Narashima) by using embryo apex

Cotton (Gossypium hirsutum L.) is one of the most commercially important fiber crops in the world. Compared with other crops, cotton represents a recalcitrant species for regeneration protocols. The development of efficient and rapid regeneration protocol for elite Indian cotton variety could help improve the quality characteristics and biotic or abiotic stress tolerance. Here we report a novel...
