DO YOU KNOW? 1. Hypersensitive cell death (or HR) is a process of programmed cell death in a plant that is associated with the plant’s reaction to pathogens. 2. Most people think plants only take in CO2 and give off oxygen, but the truth is most plants actually respire and give off CO2 as well, during the night. 3. 4. 5. Very high light intensities will break down chlorophyll, imparting a white, bleached appearance to the leaves and resulting in a decreased ability to carry out photosynthesis. A base fertilizer with multiple sources of each particular element is a good choice—this diversity allows the plant to choose the source from which the nutrients are taken. If you can’t store your harvested crops in a cold room they should be at least be stored somewhere cool, where temperatures never exceed 75°F. 6. 7. In order for a disease-resistant plant protein to be effective and result in no disease there needs to be a dominant resistance gene in the plant and a corresponding avirulence gene in the pathogen. Seedlings require a photoperiod of 18 hours of light followed by six hours of darkness. 8. 9. Tropisms are plant movements directed toward or away from a stimulus. Plants start preparing for death long before harvest, but live for some time after. 214 COMING UP IN aPRIL Maximum Yield USA | March 2012 Seeing Green Turn your garden from brown to green, from synthetic to natural, with easy tips from Maximum Yield’s or ganic experts.
