摘要

方法与结果我们描述并说明了胚胎切除的详细方法,该方法成功用于促进多种复合植物的萌芽,并且只需极少的材料和费用,我们以Layia platyglossa为例进行了说明。我们展示了与对照处理相比,这种方法如何大大提高了夏威夷银剑的近亲 Madia elegans 的发芽率。胚胎切除可以提高发芽率,在贮藏前或贮藏后对种子质量进行评估,并使幼苗同步发育,从而改善异地种子库的条件,有效利用园艺资源,从而帮助依赖极少种子资源的保护工作。

Embryo excision in Compositae, with implications for combating biodiversity loss

Embryo excision in Compositae, with implications for combating biodiversity loss

Premise

Embryo excision is an effective, under-described means of promoting germination in the sunflower family and may help to ensure the survival of endangered taxa or lineages with limited seed availability.

Methods and Results

We describe and illustrate a detailed method of embryo excision used successfully to stimulate germination in a diversity of composites and that requires minimal materials and expense, using Layia platyglossa as an example. We show how this procedure greatly increases germination compared to control treatments in Madia elegans, a close relative of Hawaiian silverswords that exhibits physiological dormancy.

Conclusions

This technique can be learned quickly and is highly effective. Embryo excision can aid conservation efforts dependent on minimal seed resources by enhancing germination and allowing evaluation of seed quality before or after storage, as well as synchronizing seedling development, thereby allowing for refinement of ex situ seed bank conditions and efficient use of horticultural resources.

期刊介绍: Applications in Plant Sciences (APPS) is a monthly, peer-reviewed, open access journal promoting the rapid dissemination of newly developed, innovative tools and protocols in all areas of the plant sciences, including genetics, structure, function, development, evolution, systematics, and ecology. Given the rapid progress today in technology and its application in the plant sciences, the goal of APPS is to foster communication within the plant science community to advance scientific research. APPS is a publication of the Botanical Society of America, originating in 2009 as the American Journal of Botany''s online-only section, AJB Primer Notes & Protocols in the Plant Sciences. APPS publishes the following types of articles: (1) Protocol Notes describe new methods and technological advancements; (2) Genomic Resources Articles characterize the development and demonstrate the usefulness of newly developed genomic resources, including transcriptomes; (3) Software Notes detail new software applications; (4) Application Articles illustrate the application of a new protocol, method, or software application within the context of a larger study; (5) Review Articles evaluate available techniques, methods, or protocols; (6) Primer Notes report novel genetic markers with evidence of wide applicability.
