Cucurbitaceae contribute to the diet of the population, as well as to the economy of farmers; but are harmed by phyto-parasites like to Meloidogyne spp. The know about the root-knot nematode is empty to put suitable strategies to management. The objectives of this research were identified species of Meloidogyne genera in cucurbitaceaes and determine their distribution and occurrence in Arequipa, Peru. Roots of Cucurbita maxima, Citrullus lanatus, Cucumis melo and Cucurbita pepo were collected, identifying them by electrophoresis for the enzyme esterase. Meloidogyne spp. is present in 87.1% from places that were evaluated and M. incognita I1 (Rm: 1.00), M. incognita I2 (Rm: 1.02 - 1.07), M. incognita S2 (Rm: 0.87), M. arenaria A1 (Rm: 1.19), M. arenaria A2 (Rm: 1.19 - 1.25), M. hapla H2 (Rm: 0.95) and one specie atypical of Meloidogyne (Rm: 0.87) were identified with occurrences of 17.14%...

The blackberry is a crop that has become important for its commercial and nutritional value, this caused its cultivation increase areas discreetly. In this sense, the objective of the present investigation was to evaluate the effect of two natural rooting agents from young stems and leaves of willows and lentil radicles and synthetic rooting agent root-hor in the propagation of cuttings and rhizomes of blackberries (Rubus Fructicosus L. ninai) during October - December. A complete randomized design (DCA) with 24 treatments and 9 repetitions was conducted. Root length, neck diameter, number of shoots and plant size were evaluated. The best results were observed in the rhizomes, where treatment T03 stood out, followed by T9, T20, T17, T19, T21, T16 and T18; Regarding the cuttings, only the T6 treatment had root. It is concluded that the best results are found when blackberry is propagated ...

Passion fruit is a versatile fruit, whose demand is increasing by the change in consumer habits. Due to the small knowledge about the process of sexual propagation, the research had as a goal to determine the best concentration of gibberellins in the germination of Passiflora edulis Sims and its effect on seeds with two different storage times. The investigation was by 45 days and were evaluated: germination percentage (PG), mean germination speed (VMG), root length and plant mass. The best results were observed when the sedes have 6 months of storage time and is soaked in gibberellins at 1000 ppm; when the seed has 0 months of storage time, the results are statistically similar at 1000, 1500 and 2000 ppm.

En Arequipa, las cucurbitáceas contribuyen en la dieta de la población y en la economía de los agricultores, pero son afectadas por fitoparásitos como meloidogyne spp. El conocimiento del nematodo de las agallas en la región, en relación al cultivo es escaso y limitante para el planteo de estrategias adecuadas de manejo. Por lo expuesto, el objetivo de la investigación fue identificar especies del género meloidogyne en cucurbitáceas mediante electroforesis para la enzima esterasa (Est), caracterizar el patrón perineal de las especies identificadas y determinar la reacción de cuatro cultivares de zapallo a dos fenotipos de meloidogyne incognita. Fueron colectadas raíces de Cucurbita maxima, citrullus lanatus, Cucumis melo y Cucurbita pepo de las provincias de Arequipa, Caylloma, Islay y Camaná; la identificación se realizó en el mega-laboratorio de Nematología en la Univer...
