We compared three Pi-efficient (ATF-14B, ATF-53B, 101B) and four Pi-inefficient (ATF-16B, 116R, 136B, 187R) sorghum genotypes under different Pi concentrations. There were no significant differences between the groups in Pi-use efficiency under Pi-deprivation for anthocyanin accumulation, dry-weight matter, acid phosphatase activity (APA), and aerenchyma formation. However, both groups showed anthocyanin accumulation under Pi-deprivation. Under Pi-deficiency, there was a significant reduction of dry weight in both groups, with no significant differences between contrasting genotypes. All genotypes exhibited a significant increase in root/shoot ratios during Pi-deficiency, and these changes were not related to Pi-use efficiency. The total Pi content in roots and shoots in all genotypes was similar and represented less than 0.2 % of the total dry weight. For all genotypes, the Pi content in P+ treatment resulted in a significant variation ranging from 0.45 to 0.85% and 0.41 to 0.66% in roots and shoots, respectively. The genotype 187R had the highest P content in roots and shoots. APA activity showed increased activity only in the roots of both groups. The development of aerenchyma was conspicuous in the basal and in the middle root sections of all genotypes grown under different Pi levels. Two sorghum Pi-transporter genes were strongly overexpressed in the middle part of Pi-deprived roots of 136B genotype. We did not find differences that explain the Pi-use efficiency between efficient and inefficient genotypes. More studies are needed to elucidate the complex mechanism of P-utilization by sorghum plants.

The Plant Response Potential to Fertilization (RPF) method, as it has been interpreted, may result in nutritional diagnoses with low efficiency. In this regard, this work aimed to validate the RPF criterion and determine the percent value to be considered as culm yield increase based on the accuracy of nutritional diagnoses for nutrient P in sugarcane by the CND method. The study used data collected from five experimental areas located in three municipalities in the state of São Paulo, Brazil, in 2013 crop year. Database comprised productivity and leaf contents of nutrients obtained from the reference population that indicated yields over 172 tons ha-1 . The CND indices were interpreted by the RPF criterion, with introduction of variable f, and accuracy was determined considering as insufficient diagnosis when the addition of P resulted in yields increase over 5; 10; 15; 20; 25; 30; 35 and 40% between the control situation and the response situation. The use of factor f ¼ 0 in the IBNm adjustment allowed to obtain higher sugarcane culm yields or lower yield losses, which corresponds to the abandonment of interpretation of nutritional indices by the RPF method. The CND is effective in assessing the plants nutritional status when culm yield increases over 35 and 40% are used as reference between the control situation and the response situation with application of P in sugarcane crops. |
