Morphological Responses Of Wheat (Triticum Aestivum L.) To Changes In Phytochrome Photoequilibria, Blue Light And Photoperiod, Charles Barnes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wheat (Triticum aestivum, L.) plants were exposed to three different levels of phytochrome photoequilibria (φ), two different photoperiods, end-of-day far-red radiation, two different levels of blue (400-500 nm) light, three levels of photosynthetic photon flux (PPF), and two types of high intensity discharge lamp types. Tillering was reduced by lowered φ, by reduced amounts on blue light and by end-of-day far-red. Main culm development was increased by lowered φ, by increased PPF, and was reduced by shortened photoperiod and by reduced blue light. Leaf length was increased by increased PPF, lowered φ, and reduced blue light but was …
