Assessm.nt of Key Players in the Special Rice Value Chain in Nueva Ecija, Philippines

Open Journal of Ecology 2023年第6期13卷 422-433页

This study traced the special rice value chain, described the various players’ roles, assessed the identified chains’ perform.nce, determ.ned the constraints and opportunities, and identified interventions to im.rove the special rice value chain in the province. Key inform.nt interviews with governm.nt and nongovernm.nt organizations (NGOs) and surveys am.ng different special rice value chain players were done. The special rice industry in Nueva Ecija is relatively lim.ted and consists of arom.tic, pigm.nted, and glutinous rice. The value chain m.pping for special rice in Nueva Ecija starts downstream.(traders) and m.ves upstream.(input provider). Som. of the identified constraints within the m.rket levels of the chain are as follows: Farm.rs’ lim.ted access to affordable yet quality seeds, the volatility of the price of paddy rice in the m.rket, and the rapid changes in the prices of production inputs, such as seeds, fertilizers, pesticides, and others. m.reover, natural factors like typhoons, floods, droughts, insect pests, and weeds were noted. One m.jor problem.identified by the institutional buyers was the lim.ted dem.nd for special rice. To im.rove com.etitiveness, the special rice industry should focus on developing and prom.ting pest-resistant varieties and cost-reducing technologies. Furtherm.re, prom.ting special rice am.ng consum.rs is needed to increase dem.nd and encourage m.re farm.rs to engage in special rice production. The governm.nt agencies should continue supporting special rice farm.rs not only in production but also in postharvest and m.rketing aspects. Provision of sem.nars, trainings, and m.chinery related to special rice is recom.ended. Regression analysis using backward m.thod of analysis was found to be significant in three (3) variables, nam.ly, household size, years in school, and labor.

***（布劳威尔）（1881-1966）为数学家所熟知，主要因为他是拓扑学家，是20世纪初期的两位拓扑大师之一——他们极大地影响了其后拓扑学的发展；另一位大师是Henri Poincare（庞加莱）（1854-1912）．所有的数学家都知道Brouwer不动点定理，大多数数学家很可能还知道有关他的若干其他成果：他第一个证明了维数的拓扑不变性和区域的拓扑不变性；他进一步发展了作为一种拓扑工具的映射度概念。

Evolutionary Genom.cs of Weedy Rice in the USA

Journal of Integrative Plant Biology 2007年第6期49卷 811-816页

Red rice Is an Interfertlle, weedy form.of cultivated rice （Oryza sativa L.） that com.etes aggressively with the crop In the southern US, reducing yields and contam.nating harvests. No wild Oryza species occur In North Am.rica and the weed has been proposed to have evolved through m.ltiple m.chanism., Including ＂de-dom.stication＂ of US crop cultlvars, accidental introduction of Asian weeds, and hybridization between US crops and Asian wild/weedy Oryza strains. The phenotype of US red rice ranges from.＂crop m.m.cs＂, which share som. dom.stication traits with the crop, to strains closely resem.ling Asian wild Oryza species. Assessm.nts of genetic diversity have Indicated that m.ny weed strains are closely related to Asian taxa （Including indica and aus rice varieties, which have never been cultivated In the US, and the Asian crop progenitor O. ruflpogon）, whereas others show genetic sim.larity to the tropical Japonica varieties cultivated In the southern US. Herein, we review what Is known about the evolutionary origins and genetic diversity of US red rice and describe an ongoing research project to further characterize the evolutionary genom.cs of this aggressive weed.
