The aim of the research was to study the effect of high temperature on the variability of male gametophyte traits in hybrid F5 populations of tomato. Thus, it was found that the high temperature has a significant effect on the variability of the male gametophyte characteristics of tomato hybrids. For the combinations under study, it was revealed that the temperature factor and genotype are the main sources of variability of the male gametophyte traits against the background of elevated temperature. As a result of the experiments, the two most heat-resistant tomato genotypes were identified.

Temperature Applications

Rapid solidification processing (RSP) is one method of producing high strength aluminum alloys for elevated temperature applications. Allied-Signal, Inc. has produced an Al-12.4 Fe-1.2 V-2.3 Si (composition in wt pct) alloy which possesses good microstructural stability up to 425°C. This alloy contains a high volume fraction (37 v/o) of fine nearly spherical, α-Al12(Fe, V)3Si dispersoids. The improved elevated temperature strength and stability of this alloy is due to the slower dispersoid coarsening rate of the silicide particles. Additionally, the high v/o of second phase particles should inhibit recrystallization and grain growth, and thus reduce any loss in strength due to long term, high temperature annealing.The focus of this research is to investigate microstructural changes induced by long term, high temperature static annealing heat-treatments. Annealing treatments for up to 1000 hours were carried out on this alloy at 500°C, 550°C and 600°C. Particle coarsening and/or recrystallization and grain growth would be accelerated in these temperature regimes.
