[Abstract]  A protocol for the axillary bud proliferation of prickly pear (Opuntia; Cactaceae) is presented. This genus is widely used as a crop in the arid and semi-arid areas of the globe worldwide, providing numerous benefits for human and animal consumption. In vitro culture for axillary bud proliferation is of great use to obtain a large quantity of plants in a short period of time, with potential uses in production and for the preservation of endangered species of the Opuntia genus.

The optimal medium for Opuntia in vitro culture consists of Murashige ...
[摘要]  提出了刺梨( Opuntia; Cactaceae )腋芽增殖的方案。 该属广泛用作全球干旱和半干旱地区的作物,为人类和动物消费提供了许多益处。 腋芽增殖的体外培养对于在短时间内获得大量植物具有重要意义,可用于生产和保存罂粟的濒危物种 属。

仙人掌体外培养的最佳培养基由Murashige和Skoog培养基(MS)和L2维生素组成。 为了增加腋芽增殖的产量,我们建议添加植物生长调节剂(PGRs)。 这项工作表明在含有2.2mg / L苄基氨基嘌呤(BA)的培养基中培养15天,然后将外植体转移到不含PGR的培养基中。 我们还解释了如何使植物适应体外条件。

【背景】仙人掌(刺梨)属是仙人掌科家族的成员之一(Bravo-Hollis,1978)。虽然它原产于美洲,但目前生长在欧洲南部,非洲北部,澳大利亚,中东,西亚和世界其他地区的野生和商业种植园中(Ochoa和Barbera,1995; Kiesling和Metzing) ,2017)。仙人掌对干旱和半干旱环境以及生活在这些地区的人类群落产生了深远的影响,因为尽管在干旱地区生长,其生物量仍然很高(Acevedo et al。,1983)。在许多这样的领域, Opuntia 属被用于许多方面。 仙人掌的幼枝可以作为蔬菜食用;水果直接食用或加工成果冻,果汁或糖果(Barba et ...

[Abstract]  A new split-root system was used to simulate non-uniform salt, drought or nutrient deficiency stress in the root zone, in which the root system was divided into two or more equal portions. Here, we established a split-root system by grafting of cotton seedlings. In contrast to the conventional split-root, the main roots of the new system remained intact, which provided a better system for studying cotton response to unequal treatment in the root zone. The new system was suitable for plant growth in nutrient solution and the two root systems can fully be immerged in the nutrient solution. [摘要]  采用新的分裂系统模拟根系中不均匀的盐,干旱或营养缺乏胁迫,根系分为两个或更多等份。在这里,我们通过嫁接棉花幼苗建立了根系。与传统的根系相反,新系统的主要根源保持不变,为根区不平等处理棉花的响应提供了更好的系统。新系统适用于营养液中的植物生长,两种根系可以完全浸入营养液中。

背景 分裂根系被用于研究植物对不均匀土壤条件的响应,如部分根部干燥,不均匀盐分布和异质营养分布。棉花和其他植物中常规的根系系统是通过在切割幼苗的主根之后将侧根分成两等份(Bazihizina等人,2009; Dong& et al。,2010)。新系统适合于营养液和环绕实验中的植物生长,因为移植物的根部和位置之间有足够的距离(Kong& et al。,2012和2016)。
