The Relationship Between Leaf Area Index And Photosynthetic Temperature Response In Wheat (Triticum Aestivum L.) Canopies, David B. Meek
The Relationship Between Leaf Area Index And Photosynthetic Temperature Response In Wheat (Triticum Aestivum L.) Canopies, David B. Meek
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The objective of this study was to determine the effect of increasing leaf area index on the photosynthetic temperature response of a wheat canopy. Hard red spring wheat (Triticum aestivum L. cv. Veery-10) was grown hydroponically in a growth chamber, which also served as the gas-exchange chamber. Gas-exchange parameters were measured on single leaves and on wheat canopies at various leaf area indices. The temperature response curves of the canopy shifted from being steeper with a high temperature optimum to being flatter with a lower temperature optimum as leaf area index increased from 0 to 20.0 m2m …
