Effect of the Plant Growth Regulator BM86 on Polyamines and Seed Set Efficiency of Cotton During the Reproductive Stage
نویسندگان
چکیده
Naturally occurring polyamines in plants have been implicated in cell division, metabolic activity, floral initiation, and fruit development. The plant growth regulator BM was formulated to stimulate seed production and fruit growth. In this study, it was hypothesized that the addition of BM would increase levels of polyamines for seed induction and have a direct benefit of improving fertilization and seed set in cotton. This benefit may enhance yield under extreme environmental conditions when endogenous polyamine content is reduced.

Effect of the Plant Growth Regulator BM86 on Seed-Set Efficiency and Yield of Cotton
The plant growth regulator BM was formulated to stimulate seed production and fruit growth. In this study, it was hypothesized that the addition of BM would increase levels of polyamines for seed induction and have a direct benefit of improving fertilization and seed set in cotton. This benefit may enhance yield under extreme environmental conditions when endogenous polyamines content is reduced.
متن کاملDifferent sowing dates affected cotton yield and yield components
This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...
متن کاملExogenous Application Of Putrescine On Cotton Ovaries Under Two Temperature Regimes
Polyamines are organic polycations that have been associated with a large number of plant growth and developmental processes, such as pollination and fruit set. Most of the research has been done in horticultural plants, with only limited information existing for cotton. Numerous studies have correlated increased fruit set with increased polyamines concentration during flowering. Therefore in t...

Sudan is a large country with an area of 1.88 million Km2, and has the second largest animal population in Africa consisting of 52.08 million sheep, 43.44 million goats, 41.76 million cattle and 4.62 million camels (MARF, 2013). The majority of animal wealth is concentrated in western Sudan (40%), followed by central Sudan (23%) (MARF, 2011). Minerals are divided into two groups, macro-minerals...
متن کاملPlant Growth Promoting Rhizobactria Enhance Salinity Stress Tolerance in Cumin (Cuminum cyminum L.) During Germination Stage
In order to investigate the effect of seed inoculation with Plant Growth Promoting Rhizobactria (PGPR) on germination and some biochemical and physiological indices of Cumin (Cuminum cyminum L.) under salinity stress, an experiment was conducted. Experimental factors were included in seed priming in five levels (seed inoculation with three strains of Pf2, Pf25 and CHA0 of Pseudomonas fluorescen...
