Root architecture describes root growth over time and space. Prior studies have examined the effects of ethylene and nutrient deficiency using ethylene precursors or inhibitors in combination with nutrient deficiency. To test if ethylene gas alone could alter root architecture in young pea plants, a 30 ppb flux of ethylene was maintained through a column(More)
Ethylene accumulation occurs in many plant growth environments. In some instances, low photosynthetic photon flux (PPF) is also a stress factor. Ethylene helps regulate the shade-avoidance mechanism and synthesis rates can be altered by light. We thus hypothesized that ethylene sensitivity in whole plants may be altered in low light.
