Resumo: | The establishment of breeding programs in melon in order to improve the phosphorus use efficiency is important to reduce the use of phosphate fertilizers and minimize the environmental and economic effects of agriculture. The objective of this work was to determine the efficiency of phosphorus use of melon genotypes cultivated in hydroponic system. The experiment was carried out in a greenhouse at the Federal Rural University of Semi-Arid, in Mossoró, Rio Grande do Norte. Evaluating 10 melon genotypes, five of which are improved cultivars (vereda, gaúcho redondo conesul (GRC), amarillo canário (Aca), gaúcho casca de carvalho (GCC) e trinity) and trinity) and five unimproved (A-02, A-16, A -29, A-50 and A-52), which were submitted to two nutrient solutions (S1 - nutrient solution without phosphorus restriction (P +) and S2- nutrient solution with phosphorus restriction (P-)). The experimental design adopted was in randomized blocks, in a 10 x 2 factorial scheme, totaling 20 treatments, with five replications. Each experimental unit was represented by a plastic pot containing 8.0 L of nutrient solution and a plant in each pot. Plants were evaluated, at 19 days after transplanting, for leaf number (NFO), stem diameter (DCA), length of the main branch (CRP), length of the root system (CSR), volume of the root system (VSR ), chlorophyll (CLO), ratio of phosphorus content in the root and aerial part P(R/A), total phosphorus (PTO), dry matter ratio in the root and aerial part MS(R/A) and total dry matter (MST). Phosphorus Efficiency (EUP), Phosphorus Acquisition (EAP) and Internal Phosphorus Use (EUTP) were also verified. The data were subjected to analysis of variance (ANOVA) and, then, the grouping of means was performed by the Scott Knott test, where significant responses were obtained. In order to have a better view of the variability between the genotypes, the hierarchical grouping was performed by the UPGMA method from the Mahalanobis distances. The genotypes were classified into groups: Efficient and Responsive (ER), Inefficient and Responsive (IR), Efficient and Non-Responsive (ENR) and Inefficient and Non-Responsive (INR). The analyzes revealed the existence of genetic variability among the genotypes for the aerial part, root system, phosphorus and dry matter variables in the solution without phosphorus restriction (P +) and solution with phosphorus restriction (P-). The P-solution affected plant growth in all genotypes, causing a reduction in NFO, DCA, CRP, VSR, PTO and MST, regardless of the genotype, with the largest reductions observed for MST, PTO, CRP, NFO and VSR, obtaining losses of 77.3; 70.5; 64.8; 60.0 and 47.7%, respectively. On the other hand, the variables CSR, P(R/A) and MS(R / A) were higher in plants in P- solution, with an increase of 50.0; 45.2 and 100%, for CSR, P(R/A) and MS(R/A), respectively. Thus, it is observed that there was an increase in CSR and a reduction in VRS when there is less phosphorus availability. However, CLO was not affected by the of phosphorus effect, since the averages estimated in solutions with and without phosphorus restriction do not differ by the Student's t test (p> 0.05). Higher EUP and EUTP were found in the solution with less phosphorus availability (P-), while the highest EAP was observed in the solution P+. Regarding the EUP, the genotypes, 'GCC' and A-29, were the most efficient in the P+ solution. In situations of low phosphorus content (P-), 'trinity', A-02, A-16, A-29, A-50 and A-52 were the most efficient. Concerning the EAP, in the P + solution, the genotypes ‘vereda’, ‘Aca’, ‘GCC’, ‘trinity’, A-29 and A-52 stood out. In the P- solution, only the 'vereda' stood out. The most efficient genotypes in the EUTP, in the P + solution, were the genotypes 'GCC' and A29, while with less availability, 'trinity', A-02, A-29 and A-52. The genotypes A-16, A-29, A-50, A-52 and ‘trinity’ were classified as efficient and responsive (ER) in the solution with less phosphorus availability |

O objetivo do presente trabalho foi avaliar a eficiência de uso de fósforo em genótipos de meloeiros cultivados em sistema de hidroponia. O experimento foi realizado em casa de vegetação da Universidade Federal Rural do Semi-Árido, em Mossoró, Rio Grande do Norte. Avaliando 10 genótipos de meloeiro, sendo cinco cultivares melhorados (vereda, gaúcho redondo conesul (GRC), amarillo canário (Aca), gaúcho casca de carvalho (GCC) e trinity) e cinco não melhorados (A-02, A-16, A-29, A-50 e A-52), que foram submetidos a duas soluções nutritivas (S1 - solução nutritiva sem restrição de fósforo (P+) e S2- solução nutritiva com restrição de fósforo (P-)). O delineamento experimental adotado foi em blocos casualizados, em esquema fatorial 10 x 2, totalizando 20 tratamentos, com cinco repetições. Cada unidade experimental foi representada de um vaso plástico contendo 8,0 L de solução nutritiva e uma planta em cada vaso. As plantas foram avaliadas, aos 19 dias após o transplantio, quanto ao número de folhas (NFO), diâmetro do caule (DCA), comprimento do ramo principal (CRP), comprimento do sistema radicular (CSR), volume do sistema radicular (VSR), clorofila (CLO), razão do teor de fósforo na raiz e parte aérea P(R/A), fósforo total (PTO), razão da matéria seca na raiz e parte aérea MS(R/A) e matéria seca total (MST). Verificou-se também a Eficiência de Uso de Fósforo (EUP), de Aquisição de Fósforo (EAP) e Utilização Interna de Fósforo (EUTP). Os dados foram submetidos as análises de variância (ANOVA) e, em seguida, procedeu o agrupamento de médias pelo teste de Scott Knott, onde foram obtidas respostas significativas. Para se ter melhor visão da variabilidade entre os genótipos, realizou-se o agrupamento hierárquico pelo método UPGMA a partir das distâncias de Mahalanobis. Os genótipos foram classificados em quadro grupos: Eficientes e Responsivos (ER), Ineficientes e Responsivos (IR), Eficientes e Não Responsivos (ENR) e Ineficientes e Não Responsivos (INR). As análises revelaram existência de variabilidade genética entre os genótipos para as variáveis da parte aérea, do sistema radicular, fósforo e matéria seca na solução sem restrição de fósforo (P+) e solução com restrição de fósforo (P-). A solução P- afetou o crescimento das plantas em todos os genótipos, provocando redução no NFO, DCA, CRP, VSR, PTO e MST, independente do genótipo, sendo as maiores reduções observadas para MST, PTO, CRP, NFO e VSR, obtendo-se perdas de 77,3; 70,5; 64,8; 60,0 e 47,7%, respectivamente. Por outro lado, as variáveis CSR, P(R/A) e MS(R/A) foram maiores nas plantas em solução P-, ocorrendo aumento de 50,0; 45,2 e 100%, para CSR, P(R/A) e MS(R/A), respectivamente. Assim, observase que houve aumento no CSR e redução do VSR quando há menor disponibilidade de fósforo. No entanto, a CLO não foi afetada pelo efeito de fósforo, uma vez que as médias estimadas nas soluções com e sem restrição de fósforo não diferem entre si pelo teste t de Student (p>0,05). Verificou-se maior EUP e EUTP na solução com menor disponibilidade de fósforo (P-), enquanto a maior EAP foi observada na solução P+. Com relação à EUP, os genótipos , ‘GCC’ e A-29, foram os mais eficientes na solução P+ . Em situação de baixo teor de fósforo (P-), ‘trinity’, A-02, A-16, A-29, A-50 e A-52 foram os mais eficientes. Concernente à EAP, na solução P+, destacaramse os genótipos ‘vereda’, ‘Aca’, ‘GCC’, ‘trinity’, A-29 e A-52. Na solução P-, sobressaíram-se apenas o ‘vereda’. Os genótipos mais eficientes na EUTP, na solução P+, foram os genótipos ‘GCC’ e A-29, enquanto com menor disponibilidade, ‘trinity’, A-02, A-29 e A-52. Os genótipos A-16, A-29, A-50, A-52 e ‘trinity’ foram classificados em eficientes e responsivos (ER) na solução com menor disponibilidade de fósforoCoordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESUniversidade Federal Rural do Semi-ÁridoBrasilCentro de Ciências Agrárias - CCAUFERSAPrograma de Pós-Graduação em Manejo de Solo e ÁguaOliveira, Francisco de Assis de81285558472http://lattes.cnpq.br/1370982860554059Nunes, Glauber Henrique de Sousa82888884453http://lattes.cnpq.br/6199153570472953Albuquerque, Cynthia Cavalcanti de76722376400http://lattes.cnpq.br/0424387651987567Graciano , Lidiane Kely de Lima01227613407http://lattes.cnpq.br/2278487003313130Nascimento, Louize2020-10-22T17:27:29Z2020-10-212020-10-22T17:27:29Z2020-05-18info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfNascimento (2020) (NASCIMENTO, 2020)https://repositorio.ufersa.edu.br/handle/prefix/5593porNASCIMENTO, Louize.

The establishment of breeding programs in melon in order to improve the phosphorus use efficiency is important to reduce the use of phosphate fertilizers and minimize the environmental and economic effects of agriculture. The objective of this work was to determine the efficiency of phosphorus use of melon genotypes cultivated in hydroponic system. The experiment was carried out in a greenhouse at the Federal Rural University of Semi-Arid, in Mossoró, Rio Grande do Norte. Evaluating 10 melon genotypes, five of which are improved cultivars (vereda, gaúcho redondo conesul (GRC), amarillo canário (Aca), gaúcho casca de carvalho (GCC) e trinity) and trinity) and five unimproved (A-02, A-16, A -29, A-50 and A-52), which were submitted to two nutrient solutions (S1 - nutrient solution without phosphorus restriction (P +) and S2- nutrient solution with phosphorus restriction (P-)). The experimental design adopted was in randomized blocks, in a 10 x 2 factorial scheme, totaling 20 treatments, with five replications. Each experimental unit was represented by a plastic pot containing 8.0 L of nutrient solution and a plant in each pot. Plants were evaluated, at 19 days after transplanting, for leaf number (NFO), stem diameter (DCA), length of the main branch (CRP), length of the root system (CSR), volume of the root system (VSR ), chlorophyll (CLO), ratio of phosphorus content in the root and aerial part P(R/A), total phosphorus (PTO), dry matter ratio in the root and aerial part MS(R/A) and total dry matter (MST). Phosphorus Efficiency (EUP), Phosphorus Acquisition (EAP) and Internal Phosphorus Use (EUTP) were also verified. The data were subjected to analysis of variance (ANOVA) and, then, the grouping of means was performed by the Scott Knott test, where significant responses were obtained. In order to have a better view of the variability between the genotypes, the hierarchical grouping was performed by the UPGMA method from the Mahalanobis distances. The genotypes were classified into groups: Efficient and Responsive (ER), Inefficient and Responsive (IR), Efficient and Non-Responsive (ENR) and Inefficient and Non-Responsive (INR). The analyzes revealed the existence of genetic variability among the genotypes for the aerial part, root system, phosphorus and dry matter variables in the solution without phosphorus restriction (P +) and solution with phosphorus restriction (P-). The P-solution affected plant growth in all genotypes, causing a reduction in NFO, DCA, CRP, VSR, PTO and MST, regardless of the genotype, with the largest reductions observed for MST, PTO, CRP, NFO and VSR, obtaining losses of 77.3; 70.5; 64.8; 60.0 and 47.7%, respectively. On the other hand, the variables CSR, P(R/A) and MS(R / A) were higher in plants in P- solution, with an increase of 50.0; 45.2 and 100%, for CSR, P(R/A) and MS(R/A), respectively. Thus, it is observed that there was an increase in CSR and a reduction in VRS when there is less phosphorus availability. However, CLO was not affected by the of phosphorus effect, since the averages estimated in solutions with and without phosphorus restriction do not differ by the Student's t test (p> 0.05). Higher EUP and EUTP were found in the solution with less phosphorus availability (P-), while the highest EAP was observed in the solution P+. Regarding the EUP, the genotypes, 'GCC' and A-29, were the most efficient in the P+ solution. In situations of low phosphorus content (P-), 'trinity', A-02, A-16, A-29, A-50 and A-52 were the most efficient. Concerning the EAP, in the P + solution, the genotypes ‘vereda’, ‘Aca’, ‘GCC’, ‘trinity’, A-29 and A-52 stood out. In the P- solution, only the 'vereda' stood out. The most efficient genotypes in the EUTP, in the P + solution, were the genotypes 'GCC' and A29, while with less availability, 'trinity', A-02, A-29 and A-52. The genotypes A-16, A-29, A-50, A-52 and ‘trinity’ were classified as efficient and responsive (ER) in the solution with less phosphorus availability |
