Abstract: O cultivo de pessegueiros é uma atividade de grande importancia econ mica no Sul do Brasil, onde se destaca o Estado do Rio Grande do Sul como grande produtor brasileiro, sendo que 50% dos pomares se encontram na Metade Sul do Estado. Um dos principais problemas do pessegueiro é o tamanho dos frutos e a produ o em épocas concentradas que dificultam a comercializa o. Com o intuito de aumentar o tamanho e expandir o período de colheita do fruto, estudou-se o efeito de aplica es de auxinas e da execu o da incis o anelar (I.A.) em ramos do pessegueiro 'Diamante'. A avalia o foi realizada no ano agrícola de 1999-2000, na Esta o Experimental Agron mica da Universidade Federal do Rio Grande do Sul (UFRGS), situada em Eldorado do Sul-RS, na latitude 30o39'S, longitude 51o06'W e a altitude de 46 metros. O delineamento experimental foi em blocos casualizados, com quatro repeti es e uma planta por parcela, com os seguintes tratamentos: 1) 10 mg.L-1 3,5,6-TPA álcool amina; 2) 20 mg.L-1 3,5,6-TPA álcool amina; 3) 30 mg.L-1 3,5,6-TPA álcool amina; 4) 20 mg.L-1 3,5,6-TPA álcool amina + (I.A.); 5) 30 mg.L-1 3,5,6-TPA ácido livre; 6) 30 mg.L-1 3,5,6-TPA ácido livre + (I.A.); 7) 25 mg.L-1 2,4-DP éster; 8) 50 mg.L-1 2,4-DP éster; 9) 75 mg.L-1 2,4-DP éster; 10) 50 mg.L-1 2,4-DP éster + (I.A.); 11) Incis o Anelar (I.A.) e 12) Testemunha. Os resultados demonstraram que os tratamentos com auxinas e (I.A.) n o aumentaram o peso total de frutos por planta. Os tratamentos com auxinas, especialmente o 3,5,6-TPA 30 mg.L-1 ácido livre, com (I.A.) ou n o, anteciparam a colheita em cerca de 20 dias. O tratamento com 30 mg.L-1 de 3,5,6-TPA ácido livre, associado à incis o anelar, resultou em incrementos de diametro e comprimento dos frutos em rela o à testemunha, porém n o diferiu estatisticamente dos demais tratamentos. Os tratamentos 3,5,6 TPA 20 mg.L-1 e 2,4 DP (éster) 75 mg.L-1 anteciparam a colheita em 20 dias e n o diferiram estatisticamente do tratamentos 30 mg.L-1 3,5,6 TPA ácido livre. A distribui o dos frutos de primeira categoria foi superior para os tratamentos 30 mg.L-1 3,5,6 TPA ácido livre + (I.A.) e 20 mg.L-1 de 3,5,6-TPA (álcool amina), embora n o diferindo estatisticamente da testemunha.

Abstract: Com o objetivo de aumentar a produ o e qualidade de frutos do pessegueiro- 'Flamecrest', de alta exigência em frio, realizou-se um experimento no Município de Farroupilha-RS, no ano de 2000, com o uso de cianamida hidrogenada e óleo mineral. Estudou-se o efeito de duas diferentes épocas de aplica o dos tratamentos (15-7 e 2-8) sobre a brota o, flora o, frutifica o, produ o e antecipa o de colheita. Foram testados os efeitos dos seguintes tratamentos: cianamida hidrogenada (C.H.) 1,22; 2,45; 3,675 e 4,90 g de i.a.L-1 com óleo mineral (O.M.) 10 g de i.a.L-1; O.M. 10 g de i.a.L-1 isolado e testemunha (sem pulveriza o). Os tratamentos n o anteciparam a brota o das gemas floríferas, porém C.H. 2,45 e 4,90 g de i.a.L-1 com O.M. a 10 g de i.a.L-1 proporcionaram plantas com maior brota o das gemas vegetativas. N o houve efeito marcante dos tratamentos sobre a flora o e a porcentagem de frutos vingados nas duas épocas. O número de frutos raleados por planta foi superior para os tratamentos com C.H. 2,45 e 4,90 g de i.a.L-1 com O.M. 10 g de i.a.L-1 quando aplicados na segunda época. Já, para o número e massa total dos frutos colhidos, destacaram-se, na primeira época (15-7), os tratamentos com C.H. 1,22 e 3,675 g de i.a.L-1 + O.M. 10 g de i.a.L-1 e, na segunda época (2-8), os tratamentos com C.H. 2,45 e 4,90 g de i.a.L-1 + O.M. 10 g de i.a.L-1. Os tratamentos da segunda época resultaram em produ es médias superiores à primeira. A massa média dos frutos n o foi alterada de forma clara pelos tratamentos, assim como o teor de sólidos solúveis totais e a resistência de polpa.
