Seed germination of Phillyrea angustifolia L., a species of difficult propagation

Ethephon Can Overcome Seed Dormancy and Improve Seed Germination in Purple Coneflower Species Echinacea angustifolia and E. pallida

Low and erratic seed germination presents a major production problem in the medicinal plants that collectively are called echinacea or purple coneflower (Echinacea angustifolia and E. pallida). In this study, nine seed lots of each E. pallida and E. angustifolia from a wide variety of commercial sources and germplasm collections were collected and treated with a solution of 1.0 mM [144.5 mg·L-1...

A STUDY ON COMPARISON OF SEED DORMANCY AND GERMINATION IN THREE SPECIES OF DODDER

A STUDY ON SEED DORMANCY AND GERMINATION IN TEN SPECIES OF GRASS WEEDS

       Seed dormancy has an important role in resistance and survival mechanisms of plants. Finding of some information about the range of primary dormancy and effective factors in dormancy breaking and optimal conditions of seed germination are necessary for weed control and other research purposes.  In this research, the seeds of 10 species of grass weeds in Tehran province fields (Echinocloa...

Seed trait changes in dispersers' guts and consequences for germination and seedling growth.

The effectiveness of a frugivore as a disperser of a plant is greatly determined by how fruits and seeds are handled in its mouth and its digestive tract. Although a number of studies have investigated the effect of avian ingestion on germination, we still know very little about the modifications to seeds during ingestion and the specific consequences on plant fitness. Here we investigate for t...
