Abstract:
... Factors affecting productivity in peach, such as flower density, initial and final fruit set by open pollination, and yield per m length of shoot were studied in 40 cultivars during a three-year period. Significant differences among cultivars were found for all studied properties. The coefficients of variability were the lowest for initial fruit set and then for final fruit set and flower density; ...
... The 15N natural abundance technique is one of those most easily applied ‘on farm’ to evaluate the contribution of biological N2 fixation (BNF) to legume crops. When proportional BNF inputs are high, the accuracy of this technique is highly dependent on an accurate estimate of the 15N abundance of the N derived from N2 fixation (the ‘B’ value). The objective of this study was to determine the influ ...
... This study reports for the first time the metabolic profile of cocoa (Theobroma cacao L.) beans using the 1H NMR technique applied to polar extracts of fermented cocoa beans. The simultaneous detection and quantification of amino acids, polyalcohols, organic acids, sugars, methylxanthines, catechins, and phenols were obtained by assigning the major signals of the spectra for different varieties of ...
... Despite increasing knowledge of 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) and 6-methoxy-benzoxazolin-2-one (MBOA) as allelochemicals involved in the defense of wheat against pests, relatively little is known about their levels in the rhizosphere and interactions with the soil microbial community. This study quantified DIMBOA and MBOA in the wheat rhizosphere and analyzed the soil micro ...

Abstract:
... 2-Methoxy-3-isobutylpyrazine (MIBP) contributes a bell pepper aroma to many grape cultivars and has a reported aroma threshold of 2 ng L−1 in water. The purpose of this study was twofold: (1) develop a procedure using headspace solid phase micro-extraction combined with GC–MS in the selected ion monitoring mode (HS-SPME-GC–MS-SIM) for analysis of MIBP in grape berries, and (2) determine the locati ...
Tropaeolum tuberosum; botanical illustration; cultivars
Abstract:
... Tropaeolum tuberosum Ruiz & Pav. (Tropaeolaceae) and its two subspecies, subsp. tuberosum and subsp. silvestre Sparre are described and illustrated, and their cultivation and propagation discussed. The origin of the cultivar 'Sidney' is noted. ...
... A comparative study of polyphenol oxidase (PPO) from two Turkish varieties of quince (Eşme and Kalecik) was conducted to determine some of the characteristics of the enzymes in terms of temperature and pH optima, substrate specificity, thermal inactivation and potency of some PPO inhibitors. PPO was partially purified by ammonium sulfate precipitation followed by dialysis. The optimum pH and tempe ...
... The citrus fruit Setomi is a hybrid of Yoshiura ponkan (Citrus reticulate Blanco) and Kiyomi (Citrus unshiu Mrcov. × Citrus sinensis Osbeck). The essential oils from the peel of Setomi and its parent cultivars were obtained by a simultaneous distillation extraction technique. Comparing the essential oils of Setomi and its parent cultivars, it was found that the oil in the peel of Setomi consisted ...

Abstract:
... Lectins/hemagglutinins are a class of sugar-binding proteins which agglutinate cells and/or precipitate glycoconjugates. They occur widely in plants but manifest significant differences in activities, which means only a few of them own exploitable potentials. The objective of this study was to find and characterize a multifunctional plant lectin with high potential values in food chemistry and med ...
... Cadmium (Cd) is a pollutant heavy metal that is naturally present in soils and highly toxic to biological organism even at low concentrations. Significant differences were observed among soybean [Glycine max (L.) Merr.] cultivars in the uptake of Cd by root and its posterior translocation to the shoot and grain. The aim of this research was to identify quantitative trait loci (QTLs) for seed Cd co ...
... Phytochemical diversity was examined by gas chromatography−mass spectrometry in tubers of genotypes belonging to groups Andigena, Phureja, Stenotomum, and Tuberosum of the potato, Solanum tuberosum. Polar extracts (mainly amino acids, organic acids, sugars, and sugar alcohols) and nonpolar extracts (mainly fatty acids, fatty alcohols, and sterols) were examined. There was a large range in levels o ...

Abstract:
... Breeding efforts to change the amino acid profile of seed protein and the assessment of genetic variation for amino acid composition among soybean germplasm resources have been hampered by lack of a rapid and inexpensive method for amino acid determination. A modified procedure presented here is partly based on a gas-phase hydrolysis and precolumn derivatization for HPLC analysis. The procedure ac ...
... The development of oilseed rape cultivars with a high content of oleic acid (18:1) and a low content of linolenic acid (18:3) in the seed oil is an important breeding aim. Oil of this quality is increasingly being sought by the food and the oleochemical industry. Since the oil quality is determined by the genotype of the seed, a selection can be performed among single seeds of segregating populati ...

Abstract:
... Shortly after its arrival, the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), became established as the most important insect pest of soybean, Glycine max L. (Merr.), in the northern part of the North American soybean production region. Soybean resistance is an environmentally sustainable method to manage the pest and new soybean aphid resistant cultivars are beginning to be deplo ...
... Korean ginseng (Panax ginseng) has been developed as a horticultural crop due to the increasing demand in the world market. “Chunpoong” is an economically important cultivar with superior quality and high yield among nine cultivars of Korean ginseng. The aim of this work was to develop a simple technique for specific authentication of Chunpoong using DNA method. Molecular authentication of Chunpoo ...
... To understand why the Pvr4 resistance of pepper against Potyvirus spp. remained durable in field conditions while virulent Potato virus Y (PVY) variants could be selected in the laboratory, we studied the molecular mechanisms which generated these variants and the consequences on viral fitness. Using a reverse genetics approach with an infectious cDNA clone of PVY, we found that the region coding ...
... Historically, extension work within Nigeria has been largely oriented towards a technology transfer or an advisory approach. However, neither pull nor push extension models have yet realized the potentials of agricultural innovations, especially that of plantain and banana (Musa spp.) cultivars. Empirical data on the adoption level of these cultivars in selected states of Southern Nigeria show tha ...
... Leaf photosynthesis, an important determinant of yield potential in rice, can be estimated from measurements of chlorophyll content. We searched for quantitative trait loci (QTLs) for Soil and Plant Analyzer Development (SPAD) value, an index of leaf chlorophyll content, and assessed their association with leaf photosynthesis. QTL analysis derived from a cross between japonica cultivar Sasanishiki ...
... Seed germination is an important character for plant growth and seed quality. We identified a rice mutant that was delayed in its germination. There, T-DNA was inserted into Oryza sativa Delayed Seed Germination 1 (OsDSG1), causing a recessive null mutation. Overexpression of the gene enhanced seed germination. OsDSG1 is most similar to Arabidopsis AIP2, an E3 ligase targeting ABI3.Yeast two-hybri ...
