Resumo: | This work aimed at comparing the growth and partitioning of assimilate in tomato plants cv. Micro-Tom subjected to nitrogen and pyraclostrobin. This substance favors the development of chloroplasts and the synthesis of chlorophyll. Tomato plants were submitted to the treatments: T1, complete nutrient solution without pyraclostrobin, T2, complete nutrient solution + pyraclostrobin, T3, ½ strength nutrient solution without N pyraclostrobin and T4, ½ strength nutrient solution N + pyraclostrobin. Plants were collected at regular intervals of seven days after transplantation throughout the crop cycle, with dry mass and leaf area being determined. From the primary data, growth analysis was carried out to calculate total dry matter (Wt), the instantaneous rates of dry matter production (Ct), relative growth (Rw) e net assimilation (Ea), leaf area (Af), production rates (Ca) and relative growth of leaf area index (Ra) and leaf weight (Fw) specific leaf area (Sa) the dry matter partitioning between organs and number (Nfr) and fresh fruit weight (Wfr). Plants of T1 showed higher Wt, Ct and Wfr compared to those of other treatments. However, the T2 plants exhibited similar Nfr to T1 plants, being superior to others. Also allocated on the total dry matter and at the end of the cycle, a higher percentage of dry matter in the seafood compared to T3 and T4 plants. Also they allocated relative to the total dry matter and at the end of the cycle, a higher percentage in fruits of plants to T3 and T4. The association between nitrogen and pyraclostrobin changes the growth and assimilated partition on tomato plants cv. Micro – Tom, and those submitted to ½ dose of nitrogen have a higher total dry matter and less final percentage of total dry matter in fruits , comparatively to those submitted to the association ½ dose of nitrogen and pyraclostrobin. |

Micro-Tom submetidas ao nitrogênio e piraclostrobina. Esta substância favorece o desenvolvimento de cloroplastos e a síntese de clorofila. Plantas de tomateiro foram submetidas aos tratamentos: T1, solução nutritiva completa sem piraclostrobina; T2, solução nutritiva completa + piraclostrobina; T3, solução nutritiva ½ força de N sem piraclostrobina e T4, solução nutritiva ½ força de N + piraclostrobina. As plantas foram coletadas a intervalos regulares de sete dias após o transplante ao longo do ciclo de cultivo, sendo determinados a massa seca e a área foliar. A partir dos dados primários, foi aplicada a análise de crescimento, sendo calculados a massa seca total (Wt), as taxas instantâneas de produção de matéria seca (Ct), crescimento relativo (Rw) e assimilatória líquida (Ea), a área foliar (Af), as taxas de produção (Ca) e de crescimento relativo de área foliar (Ra), as razões de área foliar (Fa) e de massa foliar (Fw), a área foliar específica (Sa), a partição de matéria seca entre órgãos e o número (Nfr) e massa fresca de frutos (Wfr). Plantas de T1 apresentaram maior Wt, Ct e Wfr em relação àquelas dos demais tratamentos. Entretanto, plantas de T2 apresentaram similar Nfr à plantas de T1, sendo superiores às demais. Além disso, alocaram em relação à matéria seca total e ao final do ciclo, maior porcentagem de matéria seca nos frutos comparativamente a plantas de T3 e T4. A associação entre nitrogênio e piraclostrobina altera o crescimento e a partição de assimilados em plantas de tomateiro cv. Micro- Tom, sendo que àquelas submetidas à ½ dose de nitrogênio apresentam maior massa seca total e menor porcentagem final de matéria seca total em frutos, comparativamente, àquelas submetidas à associação ½ dose de nitrogênio e a piraclostrobina.UEL2015-10-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpesquisa campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1681310.5433/1679-0359.2015v36n5p3001Semina: Ciências Agrárias; Vol. 36 No. 5 (2015); 3001-3012Semina: Ciências Agrárias; v. 36 n. 5 (2015); 3001-30121679-03591676-546Xreponame:Semina.

This substance favors the development of chloroplasts and the synthesis of chlorophyll. Tomato plants were submitted to the treatments: T1, complete nutrient solution without pyraclostrobin, T2, complete nutrient solution + pyraclostrobin, T3, ½ strength nutrient solution without N pyraclostrobin and T4, ½ strength nutrient solution N + pyraclostrobin. Plants were collected at regular intervals of seven days after transplantation throughout the crop cycle, with dry mass and leaf area being determined. From the primary data, growth analysis was carried out to calculate total dry matter (Wt), the instantaneous rates of dry matter production (Ct), relative growth (Rw) e net assimilation (Ea), leaf area (Af), production rates (Ca) and relative growth of leaf area index (Ra) and leaf weight (Fw) specific leaf area (Sa) the dry matter partitioning between organs and number (Nfr) and fresh fruit weight (Wfr).

Also allocated on the total dry matter and at the end of the cycle, a higher percentage of dry matter in the seafood compared to T3 and T4 plants. Also they allocated relative to the total dry matter and at the end of the cycle, a higher percentage in fruits of plants to T3 and T4. The association between nitrogen and pyraclostrobin changes the growth and assimilated partition on tomato plants cv.
