Abstract Nitrogen (N) and phosphorus (P) availability affect plant sexual reproduction performance. Seed as the main product of is expected to be affected by N P in parent plant. We experimentally test how parental N:P stoichiometry seed characteristics performance two grassland species. Seeds a common species ( Holcus lanatus ) an endangered Parnassia palustris were collected from plants under...

Background Thirty years ago, there was a monograph of vegetation and plant diversity in the region prepared by the Department of Forestry at the Northeast Forestry University (unpublished), but the variety of plants in the region has changed significantly over the past 30 years. In future years, the authors hope to publish a new monograph and this research is to prepare for this work. This stud...

background: reduced ovarian reserve has been known to predict poor ovarian response and poor success rates in infertile women undergoing assisted reproductive technology. ovarian reserve also decreases with age but the rate of decline defers from a woman to another. the aim of this study was to detect any difference in ovarian reserve as measured by basal serum fsh and amh between matched cohor...

Abstract Reactive power dispatch based on static synchronous compensator (STATCOM) and photovoltaic (PV) sources in coordination with reconfiguration strategy is vital task to ensure reliable operation of modern radial distribution (RD) systems. This paper introduces a novel tree seed algorithm (TSA) improve the performance RD A variant TSA intelligent flexible mechanism search proposed create ...

Rapid synchronized seed germination is desirable to ensure seedling establishment and improve crop yield. However, abiotic stresses from drought, salinity, heavy metals have a negative impact on germination. The application of silicon (Si) has emerged as promising approach for improving germination, especially under unfavorable conditions. the mechanisms Si action not been systematically studie...

Carter's mustard (Warea carteri) is an endangered, fire-stimulated annual endemic of the Lake Wales Ridge, Florida, USA. This species is characterized by seed banks and large fluctuations in plant numbers, with increases occurring in postdisturbance habitat. We investigated the mating system, patterns of isozyme variation, and effective population sizes of W. carteri to better understand its po...

Realizing the historical importance of central Indian forests in terms of ecological, social and economical perspectives and the present socio-economic changes in the community due to several reasons, the present study was conducted. It aimed at addressing the status of harvesting pattern and supply chain structure of various ethno-botanical species by the tribal communities in the Pachmarhi Bi...
