土壤盐渍化是影响植物生长和农作物产量等非常严峻的环境问题,盐渍化荒地的开发和改良成为亟待解决的全球性问题。虽然棉花是一种比较耐盐的农作物,但土壤盐分浓度过大也会对棉花产生严重的危害,尤其是种子萌发期对盐胁迫十分敏感。缩节胺(MC)是棉花生产上用来调控棉株长势长相促进丰产比较成功的植物生长延缓剂;除了控制棉花徒长,MC浸种对棉花的生理特性也会产生显著影响,可促进棉花根系发育、提高根系活力,因此MC浸...
缩节胺(MC)作为一种赤霉素生物合成抑制剂,可以增加棉花对钾离子的吸收,从而对棉花生长产生积极调节作用,但是潜在生理机制尚不清楚。本研究利用非损伤微测技术测定表明,除了增加根生物量之外,MC浸种还可以通过增加钾离子流入和/或减少幼苗根尖的钾离子外排来增加钾离子吸收。此外,该研究发现,MC处理可以引起质膜超极化,可以通过增强H +-ATPase的基因表达(HA2/5/11)、蛋白积累(GhAHAs总...
Effect of foliar application of mepiquat chloride (1,1- Dimethyl-piperidinium chloride 5% SL (W/V), a plant growth regulator, was assessed on seed cotton yield (cv. CIM-473) at Agronomic Research Stat...
In a study conducted at College of Agriculture, University of Agricultural Sciences, Dharwad, India. Effect of foliar spray of naphthalene acetic acid [NAA] (50, 100 and 150 ppm) and mepiquat chlori...
Mepiquat chloride (1,1-dimethyl-piperidinium chloride) is a plant growth regulator that can be used by producers to manage crop development, uniformity, and maturity. Field experiments were conducted ...
Research to delineate nitrogen, potassium, and mepiquat chloride (MC) effects on cotton performance has been primarily conducted with upland cotton (Gossypium hirsutum L.). A field study was conducted...
Transgenic, herbicide-resistant cotton and recently commercialized equipment to spindle-pick 38-cm rows have renewed interest in narrow-row cotton production. Published research relative to mepiquat c...
Typical applications of mepiquat chloride (1,1-dimethylpiperidinium chloride) to control excessive vegetative growth in cotton (Gossypium hirsutum L.) are broadcast- sprayed by ground or air. Mepiquat...
Mepiquat chloride (1,1-dimethylpiperidinium chloride) is widely used in cotton (Gossypium hirsutum L.) to control excessive vegetative growth. One way to apply mepiquat chloride is with a wick applica...
