Abstract

Unlike many other organisms, plants have the ability to survive and even thrive with more than two sets of chromosomes, known as a condition called polyploidy. How this impacts the physiology of those plants is convoluted and needs further study. In my attempt to relate polyploidy to various water relations traits, I completed pressurevolume curves on plants within the blackberry family, Rubus Subgenus Rubus with ploidies ranging from 2-10. As supported by many previous studies, stomatal anatomy characteristics did vary significantly with ploidy. I also found that nighfme, but not daytime, water potential showed significant variation due to ploidy. There was not significant variaioon due to ploidy in any of the pressure-volume measurements studied. Addiioonal collecioon of gas exchange data would provide more insight into these results. These studies will begin to fill a knowledge gap that currently exists in plant physiology. Addiioonally, results from this research could aid current agricultural dilemmas, such as feeding the growing human populaioon in a changing climate.
