Does Plant Root Architecture Respond to Potassium Under Water Stress? A Case from Rice Seedling Root Responses
In plants, ischolar_mains sense the availability of potassium and water. This study examined the influence of potassium availability on ischolar_main architecture and above-ground growth under water-deficit condition. We found that the growth of rice seedlings was further reduced by low potassium under water stress. We noted consider-able reduction in the ischolar_main projected area, maximum width and width-to-depth ratio. Furthermore, high potassium supply helped in sustaining the ischolar_main top and bottom angles and prevented ischolar_main steepness under mild water stress. However, high potassium availabi-lity did not result in better seedling growth. Root steepness was more influenced by water than potassi-um levels under severe water stress.
