Research ArticleOpen accessIn the author namesTemperature Effect on Rhizoctonia solani Analyzed by MicrocalorimetryAntonio Orozco-Avitia, Martin Esqueda, Amparo Meza et al.Temperature is one of the factors playing an important role in fungi growth and spread. The aim of this study was to determine the effect of temperature on the growth of ten Rhizoctonia solani isolates. Colony Growth Rate (GR) was measured in potato-agar-dextrose cultures and Metabolic Efficiency (ME) by isothermal microcalorimetry in R. solani isolates growing in a temperature range … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 22 Jul 2013 · 8,151 accessesView PDF Cite

Research ArticleOpen accessIn the author namesGenetic Variability in Rhizoctonia solani Isolated from Vitis vinifera Based on Amplified Fragment Length PolymorphismAmparo Meza-Moller, Martin Esqueda, Felipe Sanchez-Teyer et al.Problem statement: Rhizoctonia solani is a potential grapevine pathogen. In order to develop effective methods of control, it is necessary to document its genetic diversity. Approach: The objective of this study was to analyze the genetic variability of R. solani isolated from the rhizosphere of ungrafted V. vinifera var. perlette seedless planted in Sonora, Mexico using Amplified Fragment Length Polymorphism … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 8,479 accessesView PDF Cite

Research ArticleOpen accessIn the author namesBioconversion Efficiency of β-Carotene from Mango Fruit and Carrots in Vitamin AJose de Jesus Ornelas-Paz, Elhadi M. Yahia, Alfonso A. Gardea-BejarProblem statement: Bioconversion efficiency of β-Carotene (BC) in vitamin A is strongly influenced by food matrix. This efficiency has been determined mainly in typical BC sources like carrots. BC content in mango fruit is considerably high however; the bioconversion efficiency of BC from fresh mango in vitamin A has not been determined nor compared with those of typical BC sources. … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,433 accessesView PDF Cite

Research ArticleOpen accessIn the author namesOrganic Alternative for Breaking Dormancy in Table Grapes Grown in Hot RegionsConsuelo Corrales-Maldonado, Miguel Angel Martinez-Tellez, Alfonso A. Gardea et al.Problem statement: In warm-winter regions, the need for intervention of chemical means to break bud rest becomes a dominant factor for maintaining economic production of table grapes. However, the problem is more acute when farmers want to grow organic table grapes in the absence of environmentally-friendly budbreak promoters. Approach: This study aimed to evaluate the effect of a mix of … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,758 accessesView PDF Cite
