Changes in planting environment due to climate change likely to affect the pre-emergent growth of potato (Solanum tuberosum L.) having different seed tubers physiological ages

Abstract

Climate change is attributed to the changes of soil temperature and water availability in the planting environment. To study the effect of changing temperature and moisture condition on pre-emergent growth of potato seed tubers having different physiological age, a range of different temperature and moisture conditions were applied. Three temperatures (10, 15 and 20 °C) and three water potentials [wet (-0.02 MPa), dry (-0.6 MPa) and fluctuated between wet and dry] were set to two lots of cv Russet Burbank and Atlantic seed tubers that had been treated with storage temperature of 15 °C before planting to established aging. All possible combinations of seed tuber physiological age, cultivar and moisture treatments were randomized in each temperature level with 25 replications of each. Significant interactions (p
