A look at young cotton plant's roots in drought and low temperature situations
Better understanding of cotton's roots during drought and low temperatures is needed in order to grow it more effectively. An experiment was conducted by varying night and day temperatures (22/14, 30/22 degrees Celsius), and by varying water availability (well watered, drought stress). Nine cotton cultivars from nine different breeding programs in nine different states were grown in a pure sand soil under these conditions. Time of seed sprout, soil moisture, and evapotranspiration measurements were taken. Twenty days from the time of planting the plants will be pulled up in order to scan the roots. It is expected that the plants in the well watered, optimal temperature units will be healthier than the plants in the drought stressed or lower temperature units. In addition to this it is expected that the cultivars will perform based on their breeding origin; the cultivars from Arizona and New Mexico will do well in the drought stressed units. The relationship between roots, water availability, and temperature will be valuable in making decisions such as planting dates.
