The relationship between a plant and its thermal environment is a major determiner of its growth and development. Since plants grow and develop within continuously variable thermal environments, they are subjected to continuous thermal variation over their life cycle. Transpiration serves to uncouple the temperature of the plant from that of its environment in a manner that reduces the occurrence of high temperature stresses that can limit plant performance. In some agriculturally important plants, there are desirable metabolic outcomes that are associated with specific stress events (e.g. wine grapes). In these plants it is often desirable to induce temperature and water stresses of known magnitude and duration at specific points in the growing season. In this study we used a computer-controlled irrigation system that used cotton canopy temperature to control irrigation in greenhouse-grown plants over a 10-day period. The system was designed to irrigate in a manner that altered the canopy temperature relative to specific temperature thresholds (28°C, 30°C, 32°C and 34°C). The results demonstrate that automated irrigation management based on canopy temperature is capable of altering the temporal pattern of canopy temperature in a desired manner using a feed-back loop. Potential limitations on this action are related to the range of air temperatures, radiation and humidity within the environment.

Cryopreservation of ram semen results in low post-thaw survival. Thus, studies were conducted to optimize liquid-storage of chilled semen. In Experiment 1, semen collected from rams (n = 5) was extended using either milk, TRIS (tris[Hydroxymethyl]aminomethane), TEST (N-Tris (hydroxymethyl)-methyl-2-aminoethane sulfonic acid), or CJ-2 (choline-based extender) and stored at either 4℃ and 15℃. All extenders were supplemented with 5% (v/v) egg yolk. In Experiment 2, semen collected from 9 rams was distributed across TRIS or milk extenders supplemented with 5% or 20% (v/v) egg yolk, and 0 or 1% ethylene glycol (EG), during storage for 72 hours at 4℃. The effect of penicillamine, hypotaurine, and epinephrine (PHE) on motility parameters was also evaluated following storage. In Experiment 1, most of the sperm motility parameters were higher after extension, and storage at 4℃ compared with 15℃ (P P in vivo sperm viability and conception rates when using extended, stored semen for artificial insemination of ewes.

Sorghum metabolism continually adapts to environmental temperature as thermal patterns modulate diurnally and seasonally. The degree of adaptation to any given temperature may be difficult to determine from phenotypic responses of the plants. The present study was designed to see if the efficiency of quantum yield of photosystem II could be used as a measure of how well leaf tissue metabolism was able to withstand a prolonged respiratory demand caused by elevated temperatures. The efficiency of quantum yield values of Pioneer 84G62 and Northrup King KS585 commercial sorghum hybrids showed that when the hybrids were grown in a 28°C/20°C day/night cycle in the greenhouse or the field, Pioneer hybrid 84G62 withstood subsequent elevated thermal challenges better than Northrup King KS585. The same hybrids grown in a 39°C/32°C day/night cycle showed similar efficiency of quantum yield values when thermally challenged. Water-deficit stress increased the heat resistance of the tissue raising the efficiency of quantum yield of both lines to the same level. Upon recovery from the water deficit stress the differential efficiency of quantum yield values between the two lines re-appeared. The data provided in this study suggest a metabolic advantage of Pioneer 84G62 to environmental thermal challenges compared with the Northrup King KS585.
