In the present study, the reproduction potential and survival capability of the soil nematode Pristionchus maupasi was followed in 10 cm Petri dishes at different constant temperatures: 5, 10, 15, 20, 25 and 30 C. The experiment started by placing nematode eggs on each dish. The minimum number of days from eggs, at start, to adult egg producing nematodes, decreased from 7 days at 10C to 3 days ...

The current pork slaughter process is primarily optimized to reduce cooler shrink and the incidence of PSE pork. Elimination of the halothane gene and improved preslaughter handling have decreased the incidence of PSE pork and improved the water-holding capacity of the muscle; however, the chilling process has not been optimized to accommodate these changes. The hypothesis that stepwise chillin...

Exposure to non-freezing temperatures below 10 °C causes an increase in the subsequent rate of ion leakage from chilling sensitive tissue (e.g. tomato fruit). The conditions of tissue preparation and conductivity measurements necessary to accurately calculate the rate of ion leakage from excised discs of tomato pericarp tissue were determined. Under the proper conditions, the rate of leakage ex...

Conservationists often propagate rare species to improve their long-term population viability. However, seed dormancy can make propagation efforts challenging by substantially lowering seed germination. Here I statistically compare several pretreatment options for seeds of Astragalus cicer L.: unscarified controls and scarification via physical damage, hot water, acid, and hydrogen peroxide. Al...

although, grapevines do not have a high chilling requirement, its fulfillment is critical for normal development of the vines. in tropical and subtropical regions such as farrashband, in the south of iran, there is no adequate winter chilling to release bud dormancy in grapevines. so it is necessary to consider the effect of chemical dormancy–breaking agents on bud dormancy. in the present rese...

Miscanthus × giganteus is exceptional among C4 plants in its ability to acclimate to chilling temperatures (≤14 °C) and maintain a high photosynthetic capacity, in turn leading to very high productivities even in cool temperate environments. To identify mechanisms that may underlie this acclimation, RNA was isolated from Miscanthus leaves exposed to chilling and non-chilling conditions, and hyb...

Pre- and post-infection resistance mechanisms expressed by Vitis rootstocks RS-9 and Teleki 5C against second-stage juveniles (J2) of resistance-breaking populations of Meloidogyne arenaria were observed and correlated with juvenile development and nematode reproduction. Cabernet Sauvignon grape was used as a susceptible control for comparison. Similar numbers of J2 penetrated Teleki 5C and Cab...
