Dormancy in reproductive vegetative buds in creeping perennials dominating the agricultural weed flora in Scandinavia [PDF]

open access: yes, 2013
Dormancy, which is the inability to initiate normal growth under otherwise favourable conditions, is an adaptation to escape sprouting prior to seasonal cold temperatures and/or drought in areas where winters are harsh or summers dry.

Biostimulants as an Alternative to Synthetic Growth Regulators in the Micropropagation of Hippeastrum

open access: yesAgronomy
The genus Hippeastrum (Amaryllidaceae) is very popular worldwide for its attractive, colourful flowers. The aim of the research was to evaluate the possibility of replacing synthetic growth regulators added to the media with biostimulants of natural ...

Onion, Tree—Allium cepa L. (Proliferum group)

open access: yesEDIS, 2003
This document describes the tree onion (Allium cepa L., Proliferum group), also known as Egyptian onion or walking onion. It outlines the plant’s unique growth habit—producing bulbils at the top instead of flowers—and provides guidance on cultivation ...

Metabolite profiling of Dioscorea (yam) species reveals underutilised biodiversity and renewable sources for high-value compounds [PDF]

open access: yes, 2016
Yams (Dioscorea spp.) are a multispecies crop with production in over 50 countries generating ~50 MT of edible tubers annually. The long-term storage potential of these tubers is vital for food security in developing countries.

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]

open access: yes, 2009
Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.

Morphological and reproductive differences among three charophyte species in response to variation in water depth

open access: yesAquatic Biology, 2015
Some charophyte species reproduce sexually by oospores and vegetatively by bulbils, and the proportion of branch whorls that contain reproductive organs can be used as quantitative measures of the degree of sexual reproduction. We examined inter-specific

Genetic diversity, phenotypic variation and local adaptation in the alpine landscape: case studies with alpine plant species [PDF]

open access: yes, 2018
Plant survival in alpine landscapes is constantly challenged by the harsh and often unpredictable environmental conditions. Steep environmental gradients and patchy distribution of habitats lead to small size and spatial isolation of populations and ...
