GhLUX1 and GhELF3 Are Two Components of the Circadian Clock That Regulate Flowering Time of Gossypium hirsutum
陆地棉 开花时间 调控机制
2024/4/16
植物从营养生长向生殖生长转变的时机受到多个复杂环境因素和内在因素的调控，只有适时的花芽起始和开花，植物才能在适宜的环境中完成生殖生长，从而成功的繁殖后代。季节性的光周期变化作为最可靠的外界信号，是植物判断外界环境条件是否适合生殖生长的重要依据。植物通过生物钟感知日长变化，调节自身生理活动与昼夜变化相协调，然而生物钟在光周期调控陆地棉开花时间中的作用尚是完全空白。本研究通过同源比对，在陆地棉中鉴定到...
以棉纤维比强度高的科棉1号、比强度中等的美棉33B 2个品种为材料，于2006－2007年在江苏南京设置大田分期播种试验，使棉铃发育处于不同温度条件，于棉株7~9果枝第1、2果节棉铃开花时喷施6-苄基腺嘌呤（6BA）和脱落酸（ABA），研究不同的铃期日均最低气温条件下6-BA和ABA对棉花产量和纤维品质的影响。结果表明：由晚播造成的低温降低了棉花产量及纤维品质。外施6-BA、ABA对棉株中部果枝铃...
Method for the Prediction of the Rate of +b Color Change in Upland Cotton（Gossypium hirsutum L）as a Function of Storage Temperatures
+b Color Change Upland Cotton Storage Temperatures
2009/4/30
Previous studies have indicated that HVI +b values of baled Upland cotton increase due to prolonged storage with uncontrolled temperature conditions. This change in +b is accompanied by decreases in r...
Ectopic Expression of AtNHX1 in Cotton (Gossypium hirsutum L.) Increases Proline Content and Enhances Photosynthesis under Salt Stress Conditions
Ectopic Expression AtNHX1 Cotton Proline Content Photosynthesis Salt Stress Conditions
2008/12/10
Overexpression of the Arabidopsis gene AtNHX1 that codes for a vacuolar Na+/H+ antiporter in transgenic cotton significantly improved tolerance to 200 mM NaCl as measured by increases in plant height,...
Plant Hormones Alter Fiber Initiation in Unfertilized, Cultured Ovules of Gossypium hirsutum
Gossypium hirsutum Fiber Initiation
2008/5/13
Fiber initiation in two commercial cultivars of Gossypium hirsutum, MD51 and MAXXA GTO, was compared. MAXXA GTO produced significantly more fiber initials in ovules grown either in vivo or in vitro. U...
Pre- and Post-Anthesis Application of Exogenous Hormones Alters Fiber Production in Gossypium hirsutum L. Cultivar Maxxa GTO
Gossypium hirsutum Exogenous Hormones Alters Fiber Production Post-Anthesis Application
2008/5/13
In recent years, crop yield in cotton has remained constant, suggesting that some type of yield plateau has been reached within the existing cotton germplasm. This study examines the effect of exogeno...
