As humans continue to alter ecosystems through land-use activities, revegetation projects will be one important way to restore or maintain impacted plant communities. Certain species, such as knobcone pine (Pinus attenuata Lemmon), have been used in some revegetation projects because of their preferable traits. Information on seed production and viability is critical to planning effective proje...

Aphelenchoides besseyi is one of the most important parasitic nematodes in rice plants, capable dormancy seeds. This study aims to determine effects soaking seeds water and pesticides (carbosulfan, benomyl, imidacloprid) on mortality A. besseyi, seed viability, symptoms seedlings. specifically used infected with besseyi. Cold treatment (cwt) at 5-10˚C for 24 hours followed by hot (hwt) 52˚C 10 ...

Recent advances in the noninvasive analyses of plant metabolism include stress imaging techniques, mainly developed for vegetative tissues. We explored if infrared thermography can be used to predict whether a quiescent seed will germinate or die upon water uptake. Thermal profiles of viable, aged, and dead Pisum sativum seeds were recorded, and image analysis of 22,000 images per individual se...

Phomopsis longicolla is the primary cause of Phomopsis seed decay in soybean. This disease severely affects soybean seed quality by reducing seed viability and oil content, altering seed composition, and increasing frequencies of moldy and/or split beans. It is one of the most economically important soybean diseases. Here, we report the de novo assembled draft genome sequence of the P. longicol...

Dormancy is a state of metabolic arrest that facilitates the survival of organisms during environmental conditions incompatible with their regular course of life. Many organisms have deep dormant stages to promote an extended life span (increased longevity). In contrast, plants have seed dormancy and seed longevity described as two traits. Seed dormancy is defined as a temporary failure of a vi...

Changes in electrolyte leakage and viability in response to dehydration stress were examined in two species of seeds that do not survive desiccation. Leakage from silver maple (Acer saccharinum L.) seeds increased markedly as seed moisture contents decreased from 45 to 35% (fresh weight basis) and germination decreased from 97 to 5%, coincidentally. Time course curves of imbibitional leakage fr...
