Preliminary Evaluation of 29 Olive (Olea europaea L.) Cultivars for Production and Alternate Bearing, in the Huasco Valley, Northern Chile Chilean J. Agric. Res.
Tapia C,Francisco; Mora,Freddy; Santos,Alexandra I.
There is increasing interest in the development of intensively managed olive orchards (Olea europaea L.) in northern Chile. The selection of specific varieties that perform well on a particular site is considered crucial to maximizing productivity. The present study was undertaken to evaluate the productive performance of 29 varieties of olive in the Huasco Valley (28°34' S, 70°47' W), Northern Chile.The traits evaluated were: mean olive production per tree considering a longitudinal (PML) analysis over a period of five years, 2003 to 2007, total olive production in the same period (PA03-07) and alternate bearing index (ABI). The effect of variety was highly significant (p < 0.01) for all traits. In the field trial, IAP was moderate (0.52), with PML...

Effect of crop load on the phenological, vegetative and reproductive behavior of the ‘Frantoio’ olive tree (Olea europaea L.) Ciencia e Investigación Agraria
Beyá-Marshall,Víctor; Fichet,Thomas.
The aim of this study was to characterize the phenological, vegetative and reproductive behavior variables of ‘Frantoio’ olive trees in an "off’ year (with a low crop load) and an "on" year (with a high crop load). To do this, during the 2011-2012 and 2012-2013 seasons, "off" and "on", respectively, phenological variables, plant growth (shoots and roots) and reproductive growth (type of flower, fruit set and growth), were monitored biweekly. In addition, the yield per tree was assessed, and the crop load was estimated. The main results showed that crop load strongly influenced these variables. The distribution and intensity of vegetative growth, both in the roots and aboveground, decreased more and had lower intensity in the high fruiting season, with a...

Efecto de la carga de frutos en el crecimiento vegetativo, reproductivo, y dinámica nutrimental en árboles de aguacate 'Hass'. Colegio de Postgraduados
Mayahua Quiahua, Ivan.
Con el propósito de identificar la relación de la carga de frutos de árboles de aguacate ‘Hass’ en los flujos vegetativos, tipo de inflorescencias y dinámica nutrimental durante el inmediato ciclo de producción, se realizó de marzo 2007 a marzo del 2008 este estudio en un huerto ubicado en Temascaltepec, Edo. Mex. Se utilizaron 30 árboles, los cuales fueron catalogados de acuerdo a su última cosecha (2006) para formar tres tratamientos, 1) tratamiento carga alta (TCA) (˂100 kg árbol -1), 2) tratamiento de carga baja (TCB) (>50 kg árbol -1) y 3) tratamiento carga intermedia (TCI) (50 -100 kg árbol -1). Los árboles emitieron tres flujos vegetativos, en invierno, verano y otoño. El efecto residual de la carga de frutos alta, se manifestó en mayor número de...

Performance of 'Oneco' mandarin on six rootstocks in South Brazil PAB
Gonzatto,Mateus Pereira; Kovaleski,Alisson Pacheco; Brugnara,Eduardo Cesar; Weiler,Roberto Luis; Sartori,Ivar Antônio; Lima,Jurandir Gonçalves de; Bender,Renar João; Schwarz,Sergio Francisco.
The objective of this work was to assess the effect of six rootstocks on yield, fruit quality, and growth of 'Oneco' mandarin during the first seven harvesting seasons, in Butiá, Rio Grande do Sul State, Brazil. The rootstocks evaluated were: 'Swingle' citrumelo (Citrus paradisi × Poncirus trifoliata), 'Caipira' orange (C. sinensis), 'Troyer' citrange (C. sinensis × P. trifoliata), 'Rangpur' lime (C. limonia), 'Volkamer' lemon (C. volkameriana), and 'Flying Dragon' trifoliata orange (P. trifoliata var. monstrosa). Plants budded onto 'Flying Dragon' had the lowest vegetative development, which indicates the dwarfing characteristics of this rootstock, and had the highest mean production efficiency, despite low yield. Plants grafted on 'Volkamer' lemon and...

Leaf proline content and its relation to fruit load and flowering in citrus under field conditions Rev. Bras. Frutic.
Arias-Sibillotte,Mercedes; Borges,Alejandra; Díaz,Pedro; Ferenczi,Alejandra; Severino,Vivian.
Abstract Citrus species grown in temperate zones have sprouting inhibited in winter and this is retaken in spring when they also bloom. The main factor that defines the vegetative or reproductive destiny of the buds is the presence of fruits in development. Low winter temperatures slow plant metabolism, which has been reported as necessary for the expression of the reproductive program. During the winter period of the annual cycle, osmotically active compounds such as proline are increased as part of the cold tolerance response. We investigated whether the presence of developing fruit and the application of exogenous gibberellins affect the proline level in citrus leaves. In an orchard of adult ‘Montenegrina’ mandarin trees, leaf proline contents were...

Carbohydrate levels in the leaves and production consistency of the Ponkan tangerine when thinned out with Ethephon Rev. Ciênc. Agron.
Moreira,Rodrigo Amato; Ramos,José Darlan; Cruz,Maria do Céu Monteiro da; Pantoja,Lílian de Araújo; Santos,Alexandre Soares dos.
Management practices that maintain carbohydrate reserves in tangerines are necessary in order to ensure good yields. This experiment was carried out with the object of evaluating the levels of carbohydrates in the leaves, and consistency in the production of the Ponkan tangerine (Citrus reticulata Blanco) when subjected to chemical thinning with five concentrations of Ethephon for three consecutive years. The Ponkan tangerine evaluated had been grafted onto Rangpur lime (Citrus limonia Osbeck), cultivated with a spacing of 6.0 x 3.0 m and were 12 years old. The Ethephon concentrations tested were: 0; 200; 400; 600 and 800 mg L-1, applied in January of 2009; 2010 and 2011, when the fruits were of 25 to 30mm in transverse diameter. The experimental design...
