| Abstract/Contents: | "Bentgrass selections differ significantly in average root lengths under an array of temperatures and seasons. There are also significant differences among clones in degree of P deficiency symptoms at temperatures from 5-10° C and response to P applications. Some clones remain green and unaffected while others become reddish or purple. Purple clones have low P uptake rates at low temperature as shown by leaf analysis and 32p uptake studies. One green clone remains green at tissue P levels comparable to those of the purble [purple] clones, while others have much higher uptake rates under cool conditions. Major genetic differences in uptake at 5° C root temperatures as measures by 32P are in transport from roots to leaves, rather than absorption. Tissue analyses show little relationship between average root lengths and leaf P content at low temperatures. Genetic differences in P responses relate primarily to uptake rates, rates of transport, and threshold needs." |
