“…Another factor that can increase the SS content in fruits is the decrease of the water availability during ripening, with the increase of the internal concentration of sugars. These effects were observed on Tahiti limes (Miranda and Campelo Junior, 2010) and in Pera orange trees in northern Paraná (Tazima et al, 2010).…”

Periods of Weed Interference on Orange Tree Crops

Current orange tree cultivation practices in the Brazilian State of Amazonas present several production problems, being the inadequate weed management the most important one, and significantly affecting fruit productivity. However, if weeds are managed properly, their coexistence with orange cultivars does not affect the fruit yield of orange trees. Thus, the objective of this research was to identify the period of longer weed interference in orange production. The treatments were conducted during the 2013 and 2014 harvests as follows: one control treatment with no coexistence of weeds and crop throughout the growing season; and six periods of coexistence (October to January, February to May, June to September, October to May, October to January, June to September, and February to September). The coexistence of weeds from October to May with orange trees increased the fall of unripe fruits and reduced the yield and the number of oranges per plant. Therefore, this period was considered as the most critical one for the control of weeds in orange trees.

“…Although plants with a greater number of fruits accumulate less sugar, due to the greater competition for photoassimilates, in this case, the photosynthetic rate at the end of the water restriction period was higher in the treatments with no weeds (Figure 2). It must also be taken into account that the decrease in water availability during the ripening of Persian lime fruits leads to an increase in the internal concentration of sugars (Miranda & Campelo Júnior 2010). However, even with differences among the treatments, none of them affected the Persian lime fruits at a level high enough to declassify them from the standard required for commercialization, which is 6.5 ºBrix.…”

Weed interference in young citrus orchards causes significant damages, especially when competition occurs during the dry season, when environmental resources are even more scarce. This study aimed to test the effects of interference periods and weed management on the physiology, yield and quality of Persian lime fruits, during the dry season. The experimental design was randomized blocks, with five treatments [hoeing; glyphosate application; decrease of stored water (March to May); critical water deficit (June to August); and water deficit throughout the dry season (March to August)] and four replications. Weed interference during the decrease of stored water and critical water deficit periods affected significantly the physiological variables, yield and total solids contents of the fruits, but to a lesser extent than for the water deficit throughout the dry season. Weed control with glyphosate resulted in 1.56 and 2.53 times more fruits per tree than hoeing and water deficit throughout the dry season, respectively. The chemical management provided better physiological and productive responses than hoeing, due to the effect of weed mulch in the water deficit season.

The aim of this study was to evaluate 12 rootstock varieties on the development and quality of ‘Tahiti’ acid lime fruits cultivated in the municipality of Jaíba, MG. Seedlings were planted in an experimental orchard in November 2008, using 8 x 5 meters spacing and drip irrigation. The experiment was conducted using a scion cultivar (Tahiti acid lime, IAC-5 cultivar) and the following 12 rootstocks: ‘Rangpur’ lime, ‘Troyer’ citrange, ‘Carrizo’ citrange, 1707 hybrid (Rangpur lime x Swingle trifoliate), 1710 and 1697 citrandarins, 1708citradia, ‘Swingle’ citrumelo, ‘Cleopatra’ and ‘Sunki’ mandarins, ‘Volkamer’ lemon, and ‘Limeira’ trifoliate. A randomized block design with five replicates and three trees per plot was used. Trunk diameter of both rootstock and scion, as well as height, diameter, and canopy volume, yield, fruit mass, number of fruits per tree, productivity, production efficiency index, longitudinal diameter, equatorial diameter, total soluble solids, total acidity, and vitamin C content of fruits were evaluated. ‘Volkameriano’ and ‘Cleopatra’ rootstocks promoted higher plant vigor and productivity for ‘Tahiti’ acid lime. However, ‘Limeira’ trifoliate and ‘Troyer’ citrange produced less vigor, but increased production efficiency; and can be used as alternative rootstocks for ‘Rangpur’ lime, as long as adjustments are performed in the planting spacing to increase productivity. In general, no differences in physical and chemical characteristics of fruits for all treatments were found, and fruits remained within commercial standards.
