Seed-coat thickness explains contrasting germination responses to smoke and heat in Leucadendron.
Fire stimulates the germination of most seeds in fire-prone vegetation. Fruits of (Proteaceae) are winged achenes or nutlets that correlate with their requirements for smoke and/or heat in promoting germination. We describe five possible smoke–heat dormancy-release/germination syndromes among plants, of which displays three (no response, smoke only, smoke and heat).... -

Stimulatory and inhibitory effects of light on Cereus repandus (Cactaceae) seed germination are strongly dependent on spectral quality.
In small seeds, light often promotes germination and longer-term exposure to darkness reduces light sensitivity. In cacti inhabiting harsh environments, a rapid response to light exposure is potentially advantageous for seedling establishment. We exposed dark-imbibed seeds of the cactus to doses of red (RED) light and far-red (FR) light. The...Yang, X-Y. ; Pritchard, Hugh W.

Potential Distribution of Cedrela odorata L. in Mexico according to Its Optimal Thermal Range for Seed Germination under Different Climate Change Scenarios.
Cedrela odorata is a native tree of economic importance, as its wood is highly demanded in the international market. In this work, the current and future distributions of C. odorata in Mexico under climate change scenarios were analyzed according to their optimal temperature ranges for seed germination. For the present... -

Seed imbibition and metabolism differentially contribute to initial assembly of the soybean holobiont.
Seed germination critically determines successful plant establishment and agricultural productivity. In the plant holobiont's life cycle, seeds are hubs for microbial communities’ assembly, but what exactly shapes the holobiont during germination remains unknown. Here, 16S rRNA gene amplicon sequencing characterized the bacterial communities in embryonic compartments (cotyledons and axes) and... -

A pain in the grass–The trials and tribulations of propagation.
Initial difficulties in germinating the dropseed grass (A. Gray) A. Gray and the ways in which they were it was overcome are described. The resulting seedlings are grown in deep plugs before being planted out in the developing prairie.Jenkins, Chris

Thermal Niche for Seed Germination and Species Distribution Modelling of Swietenia macrophylla King (Mahogany) under Climate Change Scenarios.
Swietenia macrophylla is an economically important tree species propagated by seeds that lose their viability in a short time, making seed germination a key stage for the species recruitment. The objective of this study was to determine the cardinal temperatures and thermal time for seed germination of S. macrophylla; and...
