Population Genomics of Weedy Crop Relatives: Insights from Weedy Rice
2020Weedy crop relatives can evolve as a byproduct of the domestication process, and most modern crop species have conspecific or congeneric weedy relatives. These weedy relatives invade crop fields and aggressively outcompete desirable cultivars through a suite of weediness traits. Weedy rice (Oryza sativa f. spontanea) is a highly morphologically diverse

Inheritance of Seed Dormancy in Weedy Rice
Crop Science, 2003Seed dormancy contributes to the adaptability of plants in nature and is of considerable importance in agriculture. The weedy rice (Oryza sativa L.) strains LD, SS18‐2, and TKN12‐2 and cultivar ‘N22’ were selected to investigate the inheritance of dormancy in controlled conditions.

Modeling the Development of Cultivated Rice and Weedy Red Rice
Transactions of the ASABE, 2011Development models are an important part of crop simulation models and are useful tools for field operations. The objective of this study was to simulate the development of cultivated rice and weedy red rice with a linear model (thermal time model) and with a non-linear model (WE model).

Weedy rice (Oryza sativa) II. Response of Weedy Rice to Seed Burial and Flooding Depth
Weed Science, 2012Weedy rice is a serious problem of cultivated rice in most of the rice-growing areas in Asia, causing increased production costs and yield losses in rice. A study was conducted to determine the response of weedy rice accessions from India (IWR), Malaysia (MWR), Thailand (TWR), and Vietnam (VWR) to seed burial and flooding depths. The greatest emergence

ALL ROADS LEAD TO WEEDINESS: STORIES ABOUT WEEDY RICE ORIGINS, WEEDY GENES AND WEED COMPETITIVENESS
2017Over the last ten years, charter schools have become a viable choice for parent’s seeking an alternative to traditional public schools. However, research shows this is not the case for students with disabilities. The purpose of this dissertation was to examine special education in charter schools and traditional public schools located in Massachusetts.

Phylogenetic origin and dispersal pattern of Taiwan weedy rice
Pest Management Science, 2019AbstractBACKGROUNDKnowledge of the genetic diversity and spatial structure of Taiwan weedy red rice (WRR) populations, which adapted in a transplanting system, will facilitate the design of effective methods to control this weed by tracing its origins and dispersal patterns in a given region.RESULTSTaiwan WRR is genetically most similar to Taiwan ...

Strategies to manage weedy rice in Asia
Crop Protection, 2013Weedy rice, an emerging problem in Asia, increases production costs and reduces farmers' income through yield reduction and through lowered rice value at harvest. Rice farmers in many Asian countries are shifting from transplanting to direct seeding; however, due to physical and physiological similarities of weedy rice to cultivated rice and the ...

Glyphosate sensitivity in Italian weedy rice
2013Weedy rice (Oryza sativa L.) is one of the most problematic weeds of rice cultivation worldwide. An effective control technique is the application of the stale seedbed which consists of preparing the field early in the season and then flooding it to stimulate weed germination.
