Seed dormancy and germination of an endangered coastal plant Eryngium maritimum (Apiaceae)
Eryngium maritimum is a coastal plant of the Apiaceae family. This species is threatened in several countries where it reaches the northern limits of its distribution area. Existing populations in the Baltic Region and Scandinavia are potentially affected by the low efficiency of its generative reproduction. We studied physiological aspects of its germination and dormancy breaking requirements ...
متن کاملThe conservation physiology of seed dispersal.
At a time when plant species are experiencing increasing challenges from climate change, land-use change, harvesting and invasive species, dispersal has become a very important aspect of plant conservation. Seed dispersal by animals is particularly important because some animals disperse seeds to suitable sites in a directed fashion. Our review has two aims: (i) to highlight the various ways pl...
متن کاملPhytochemical constituents and pharmacological activities of Eryngium L.(Apiaceae)
Eryngium L. is the largest and arguably the most taxonomically complex genus of the family Apiaceae. The genus has approximately 250 species throughout the world, with the center of diversity in South America. Some Eryngium species are cultivated as ornamental, vegetable, or medicinal crops for folk uses. With increasing chemical and biological investigations, Eryngium has shown its potential a...
متن کاملPhylogeography of the endangered Eryngium alpinum L. (Apiaceae) in the European Alps.
We studied the phylogeography of Eryngium alpinum by sequencing two intergenic chloroplast spacers, trnH-psbA and trnS-trnG (1322 bp). The sampling design included 36 populations and 397 individuals spanning the entire distribution range of the species, from France to Bosnia. Twenty-one haplotypes were characterized and polymorphism was observed both within and among populations. Population dif...
متن کاملMicropropagation of the narrow endemic Hladnikia pastinacifolia (Apiaceae)
The monotypic Hladnikia pastinacifolia Rchb. is a narrow endemic species, with an extremely small distribution area in Slovenia, prone to any kind of threat that could lead to species extinction. Tissue culture techniques are proposed as a conservation measure for rapid propagation and ex-situ conservation. Tissue culture was initiated from seeds and juvenile plants obtained from natural sites ...
