growth over the past two decades, accompanied by the development of large-scale industries and services. In the course of this expansion, medium-sized cities and small towns have sprung up around the larger cities, forming city clusters, often with similar or interdependent economies. The development of city clusters in China is somewhat similar to the formation of the megalopolis in the United...

Pine seed mass is isometrically related to samara shape among smaller seeded pines (< 165 mg), but not when larger seeds are included (putative bird-dispersed pines excluded). Among the largest pine seeds samara length declines with increases in seed mass. Consequently, disc-loading increases and dispersal capacity declines at an accelerating rate with increases in seed mass. The acceleration i...

To determine whether treatment with a potent protease-resistant analog of human glucagon-like peptide 2 (GLP-2) might augment the adaptive response to massive intestinal resection, rats were divided into resected, which had 75% of the midjejunoileum removed, sham-resected, and nonsurgical groups. Within each group, animals were assigned to 21 days of treatment with the drug (0.1 μg/g of the GLP...

abstract in order to study the effect of planting season (autumn and spring) and plant density on growth traits and flower yield (dry weight of flower) of matricaria (matricaria chamomilla), an experiment was carried out at the research field of agricultural faculty of shirvan, affiliated to ferdowsi university of mashhad. a split plot design with two factors, including planting time and plant ...

Angiosperm fruits typically consist of pericarp and seed, which collectively function to maximize plant reproductive success. Within-fruit reproductive allocation has been scarcely examined across a wide range of fruit types and taxa although it is critical to the understanding of the evolution of fruit size and seed size. We investigated seed size, fruit size, seed number per fruit (SNF), and ...

Tef is a small-seeded staple crop endemic to Ethiopia. However, its yield low, constrained partly due improper agronomic practices and lodging. Thus, during the 2019–2020 cropping season, field experiment was carried out at Reef Tokko Taanne Hamilee in Hababo Guduru district, Western Ethiopia examine effects of seed rate inter-row spacing on growth, phenology, yield, lodging severity tef crop. ...
