不同灌溉方式对玉米根毛生长发育的影响

The mechanism of root hair development and molecular regulation in plants;

植物根毛生长发育及分子调控机理

The observation of microstructure showed that seed roots of RM109 had no lateral rootsand root hair was less and shorter, but cv.

显微结构观察表明,RM109种子根外表根毛稀少且短小,无侧根发生,而“大力”品种则有侧根发生,且密生根毛。

In the first group,the root hairs did not form on the main roots,but formed a lot on the base part of the lateral roots.

自韩素芬等(1998)首次报道了根瘤菌可诱发刺槐根表面产生传递细胞,笔者在对合欢的研究中又发现了类似的情况,同时还发现根瘤菌不仅能诱导合欢根表面传递细胞的形成,而且在水培的情况下还能诱导合欢侧根根毛的产生。

To elucidate the mechanisms of the toxicity of Al to leguminous plants at initial stages of symbiotic nodulation,the effects of Al on the growth of primary root,root hair deformation(RHD),nodulation of Medicago sativa L.

以紫花苜蓿为材料,探讨了铝对根伸长、根毛变形、结瘤和苜蓿根瘤菌(Rhizobiummeliloti)生长的影响,旨在阐明豆科作物共生结瘤的初期铝毒害的机制。

Effects of low pH on root hair deformation(RHD)and nodulation in Medicago sativa were investigated and corresponded mechanisms was also discussed in present study.

探讨了低pH条件下紫花苜蓿根毛变形和结瘤受到的影响及其机制。

Under neutral pH condition, applying Ca2+ didn’t have any significant effects on root hair deformation, while under low pH condition, Ca2+ demonstra.

中性pH条件下,Ca2+的加入对苜蓿根毛变形率无显著影响;低pH条件下,加入2、5和10mmol·L-1的Ca2+均可提高根毛变形率,Ca2+浓度越高,其影响越显著,说明低pH下Ca2+可能会促进苜蓿根瘤菌与其宿主之间的识别。

The idebitmg effect of combmed N on met hair defonnaion of alfalfa mduced by the supematan of the cultUre solution of Rhizobium meliloti was studied Nitrae and ammonia could ef fectively inhibit root hair deformation(Fig.

以苜蓿根瘤菌和其宿主苜蓿为材料，由结合态氮影响苜蓿根瘤菌生长液诱导宿主根毛变形的功能发现，硝态氮和铵态氮均能有效地抑制根瘤菌生长液诱导的宿主根毛变形。
