| ABSTRACT Mini-grafting is a type of grafting that has been indicated to increase efficiency of forest and fruit species propagation. The aim of this study was to evaluate the mini-grafting technique as a method for propagation of guava grafted on intra or interspecific rootstock. The experimental design was randomized blocks, with four treatments, five replications and plots consisting of ten plants, in a 22 factorial arrangement, and factors consisted of rootstocks and canopy cultivars. Rootstocks used were Psidium guajava and Psidium guineense. The canopy used was Paluma and Cortibel 1 cultivars. Only thecanopy used had an effect on the percentage of grafting success of 52, 54, 82 and 84%, respectively, for ‘Cortibel 1’/P. guineense; ‘Cortibel 1’/P.... |

| ABSTRACT Meloidogyne enterolobii has severely compromised the main guava producing regions in Brazil, thereby stimulating the development of resistant varieties for efficient management of this nematode. This study aimed to assess the penetration, development, reproduction, and induced cellular responses of M. enterolobii in roots of four species of the genus Psidium (P. guajava‘Paluma’, P. guineense, P. cattleyanum, and P. friedrichstalianum) from the Active Germplasm Bank (BAG) of the Center for Agricultural Research of the Semi-arid Tropics (Embrapa Semi-arid) located in Petrolina, PE, Brazil. Three experiments were carried out to assess the penetration, development, and reproduction of the nematode and, subsequently, histological analyses were... |
