植物用于防御的资源有限,而那些具有生物防御的物种,其叶片可能会较少地用于其他类型的防御。我们比较了机械防御能力较弱,但具有花外蜜腺的植物,与没有花外蜜腺但叶片更有韧性的植物是否更不容易被取食。我们通过分析文献数据,调查有无花外蜜腺的植物被取食的情况。在巴西南部的热带稀树草原植被中,我们采集了6种热带植物的叶片数据,并测定了被取食情况和比叶面积。我们进一步评估了有无花外蜜腺的物种之间以及植物之间被取食情况和比叶面积的差异。为了检验动物取食与叶片韧性之间的关系,我们对单株平均被取食情况和平均叶片韧性进行了回归。研究结果表明,植物表现出不同程度的叶片损伤,但没有蚂蚁防御的植物因被取食造成的叶面积损失最大。不同植物的机械防御水平也不相同。无花外蜜腺的植株更坚韧,比叶面积值更小。虽然无花外蜜腺的植物有更多的坚硬叶片,但这种机械防御不足以损害和/或减少食草动物的取食,这表明由蚂蚁形成的生物防御可能比用于与叶片适口性相关的机械防御更有效。

Periclinal Chimera: A New efficient Plant Breeding Technique

引用

Advances in Bioscience and Biotechnology 2022年第10期13卷 460-467页

作者： Nagib M. A. Nassar departamento de genética e Morfologia Universidade de Brasília Brasília Brazil

Periclinal chimera plants could be synthesized by a very easy grafting method. Thanks to this technique we can transfer useful characters from one genotype to another, we also can produce vigorous plants during a very short period. Recently in cassava, resistance to nematode could be transferred, and could develop vigorous plants by combining two types that have high combining ability. The most striking feature is that we can obtain enormous roots up to five times the common ones. By using this type of chimera we can replace traditional hybridization and no need to recurrent crosses cycles to transfer useful characters, reducing to a very short period developing a new variety and perpetuating it too.
