The effects of white light and decapitation on the initiation and subsequent emergence and elongation of lateral roots of apical maize (Zea mays L. cv LG 11) root segments have been examined. The formation of lateral root primordium was inhibited by the white light. This inhibition did not depend upon the presence of the primary root tip. However, root decapitation induced a shift of the site o...

abstract heavy metals uptake and their distribution in plants are different. in addition to the genetic factors, environmental factors such as interactions of heavy metals with essential elements are very important on the amount of heavy metals uptake. in this study, the effects of iron and manganese on accumulation of cadmium in shoot and root of sunflower and corn in different concentration o...

Root systems play important roles in plant nutrient and water uptake. The spatial distribution and structure of root systems can affect many physiological functions, carbon distribution, and plant anchorage. The accurate measurement of root systems is necessary for better understanding of plant growth and responses to biotic and abiotic stress. Due to their underground growth habitat, root syst...
