Photo-temperature response of ramie (Boehmeria nivea (L.) Gaud.) male sterile lines
lower Budding Acceleration Photoperiod Sensitivity
2013/3/4
Six male sterile lines (MSLs) of ramie (Boeh-meria nivea (L.) Gaud.) were grown in dark rooms under the photoperiods of 9.5h, 11h or 12.5h d-1 in spring and summer seasons (dif-ferent environmental te...
Genetic Diversity among Wild Resources of the Genus Boehmeria Jacq. from West China Determined Using Inter-simple Sequence Repeat and Rapid Amplification of Polymorphic DNA Markers

Ramie (Boehmeria nivea L.Gaud) is planted as an important fiber crop in China. Randomly amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR) markers were used for the first time fo...
植物净光合速率(Pn)测定的取样技术决定结果的可靠性,但很少有文献专门论述.为此,分析苎麻Pn的日变化、个体间、叶位间和叶片不同位点的差异,结果表明:1天中苎麻Pn在11:00左右达到最高值,此后迅速降低,虽在下午可能回升,但不同品种有差异;品种内个体间Pn差异显著;不同叶位以顶部展开叶往下数第5～7叶Pn最高;叶片不同位点的Pn差异不显著.据此建议苎麻品种的Pn测定在上午9:00～11:00进行...
苎麻(Boehmeria nivea(L)Gaud)的快速繁殖
苎麻 快速繁殖
2008/2/21
苎麻是轻纺工业的重要原料。在目前生产中,一直沿用种子繁殖或分蔸繁殖。种子繁殖虽快,但容易产生变异;而分蔸繁殖又有需要种蔸多,繁殖系数低等缺点,故使生产,尤其是良种的繁殖推广受到极大的限制。因此,探索新的繁殖方法,配合育种加速扩大良种繁殖乃是当前苎麻生产发展的当务之急。
