Results (F-values) of GLMs among germination percentages of Leptochloa chinensis (L.) Nees seeds at different seed storage, agricultural regions, and rice planting methods of seed collecting fields.
Source publication
Leptochloa chinensis (L.) Nees is a troublesome rice weed. We collected 242 L. chinensis populations from rice fields in eastern China and studied the duration of seed dormancy and the seed germination ability at different temperatures. All L. chinensis populations studied exhibited seed dormancy. The periods required to reach 50% germination under...

... with mature seeds were randomly collected from more than 100 individuals of each population with a pollen bag (100 mesh, 30 cm by 45 cm), and mature seeds were collected by hand. An interval of >5 km was set for adjacent populations (Figure 1, Table S1). All counties cultivating rice in Jiangsu Province were visited. ...Context 2
... counties cultivating rice in Jiangsu Province were visited. Jiangsu Province was divided into six agricultural regions: Xuhuai (XH), Yanhai (YH), Lixiahe (LXH), Ningzhenyang (NZY), Yanjiang (YJ), and Taihu (TH) [12]; and Jiaxing City, which belongs to Zhejiang Province, was set as another agricultural region (Figure 1; Table S1). The longitude, latitude, agricultural regions, and rice planting methods of each L. chinensis population were recorded. ...Context 3

Seed germination is a complex process involving imbibition, activation and subsequent growth. In addition to re-establishing metabolic activity, water uptake helps stabilize macromolecules and biochemical reactions, resulting in radicle protrusion. Factors affecting water uptake include seed composition, water availability and seed coat permeabilit...
