The symbiotic potential of Bradyrhizobium japonicum isolates indigenous to seven Korean soils was evaluated by inoculating soybeans with 10- and 1,000-fold-diluted soil suspensions (whole-soil inocula). At both levels, significant differences in the symbiotic potential of the indigenous B. japonicum isolates were demonstrated. The relationship between rhizobial numbers in the whole-soil inocula...

One hundred thirty-eight consumers evaluated steaks from the complexus (CX), infraspinatus (IF), serratus ventralis (SV), supraspinatus (SS), and triceps brachii (TB) from the wholesale beef chuck; the deep pectoral (DP) from the wholesale brisket; and the longissimus thoracis (LT) from the wholesale rib. The LT was used as a reference for comparison to the other muscles. Ten USDA Choice and te...

This study aimed to determine physicochemical parameters for obtaining prediction equation in order to evaluate the postharvest quality of tomatoes (Solanum lycopersicum L.). A imaging system was used to measure L*a*b* color space. In tomatoes (variety Caiman) were evaluated weight loss, oBrix, pH, titrable acidity, firmness and oHue over 17 days of storage. The experimental results demonstrate...

Activities Objective 1. Evaluate methods of sampling and measuring flavor and nutrition of fresh-cut products to facilitate comparison to traditional shelf life factors.  Barrett and Negre and other colleagues completed work on aroma volatiles and flavor quality in melons. See Vallone et al., 2013 publication.  Cantwell and associates are studying the relationship between ammonia concentratio...

To elucidate how temperature affects bradyrhizobial ecology, long-term incubations of Bradyrhizobium japonicum USDA 6(T), 38, and 123 and of Bradyrhizobium elkanii USDA 76(T) were conducted under various temperature conditions. Proliferative traits in liquid culture and population occupancies in soil microcosms were compared. The occupancies of USDA 76(T) and USDA 123 in soil microcosms during ...

In a split-root system of soybeans (Glycine max L. Merr), inoculation of one half-side suppressed subsequent development of nodules on the opposite side. At zero time, the first side of the split-root system of soybeans received Rhizobium japonicum strain USDA 138 as the primary inoculum. At selected time intervals, the second side was inoculated with the secondary inoculum, a mixture of R. jap...
