概括

优化欧亚 (Populus tremula) 的微传播需要仔细使用植物生长调节剂. 特定的组合,如paclobutrazol和GA4 / 7,促进芽和根的形成,提高克隆效率.

科学领域:

植物生物技术植物生物技术
林业科学林业科学
植物生理学植物生理学

背景情况:

欧亚 (Populus tremula) 在生态和经济上具有重要意义.
微繁殖对于快速克隆选定的虫基因型至关重要.
植物激素,特别是细胞激素,影响着发芽的诱导,但可以抑制植根.

研究的目的:

为了确定最佳的度和组合的生长调节剂的Populus tremula有机生成.
刺激发芽和根的形成,而不会抑制其他过程.
为了提高欧亚青的微繁殖效率.

主要方法:

研究的6 - 氨基 (BAP),2,3,5-三二酸 (TIBA),英多尔-3-酸 (IAA),英多尔-3-黄油酸 (IBA),帕克洛布特拉 (PBZ) 和GA4/7的作用.
估计每种种植的发芽数量和偶然的根形成.
评估了生长调节剂组合,以实现平衡的器官生成.

主要成果:

无论是BAP还是TIBA,都提高了芽的扩散,但减少了偶然的根植.
与BAP不同的是,TIBA促进了芽生长,而不会抑制横向根部的发育.
帕克洛布特拉 (PBZ) 和GA4/7的组合显著保持了树枝和根的形成在控制水平以上.

结论:

特定的植物生长调节剂对Populus tremula的芽生长和根源器官产生有差异的影响.
蒂巴为BAP提供了一个潜在的替代品,用于在没有根植抑制的情况下诱导射发.
PBZ和GA4/7的组合显示出在树微型繁殖中同时发芽和根部发育的前景.

Plant Tissue Culture

Plant Tissue Culture

Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.

Cell Culture

Cell Culture

Most vertebrate cells grow in vitro attached to a substrate as a monolayer, called adherent cultures. The flasks and plates used to grow cells are chemically treated to facilitate cell attachment. However, a few cell types, such as hematopoietic cells, can grow in a suspension. In contrast to adherent cultures, suspension cultures can grow in non-treated cultureware using magnetic stirrers or spinner flasks to agitate the culture media

Transgenic Plants

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Primary and Secondary Growth in Roots and Shoots

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.
