ABSTRACT: The 'Montenegrina' mandarin ( Citrus deliciosa Tenore) is widely cultivated in southern Brazil. This cultivar has a great tendency for alternate bearing, requiring thining of the fruit. However, chemical thinners studied until now this have not been successful. objective research was to evaluate effect 3,5,6-trichloro-2-pyridinyloxyacetic acid (3,5,6-TPA) on production and fruit quality mandarin, comparison with hand thinning options previously studied. Hand no were used as...
O objetivo foi verificar a influência do sistema de cultivo, orgânico e convencional, sobre as características físicas químicas aceitação pelo consumidor laranjas 'Valência' (Citrus sinensis (L.) Osb.). Os pomares foram instalados no município Montenegro, em julho 2001, espaçamento 2,5mx5,0m, cada um possuindo uma área 0,25ha. As avaliações realizadas partir amostras frutos colhidas setembro outubro 2011 2012. parâmetros físicos químicos analisados nos foram: teor suco (TS), sólidos solúveis...
This study aimed to evaluate the yield and chemical composition of essential oil immature fruits C. deliciosa varieties cultivated in Rio Grande do Sul using laboratory (hydrodistillation) industrial (scarification) methods. During period processing (scarification), from same batches were sampled for hydrodistillation. Essential evaluated by GC/MS GC-FID The average obtained was 0.07 wt.% 0.53 (scarification). EO followed a quadratic model regarding sample collection time both methods,...
Abstract The aim of this work was to study the phenology several sweet orange cultivars and their relationship with accumulated degree-day (ADD), under conditions Depressão Central Rio Grande do Sul, in Southern Brazil. For this, 25 genotypes were evaluated for three consecutive growing seasons between 2015 2018. experiment carried out a Citrus Collection located municipality Eldorado RS, ADD calculated each interval phenological stages, as well entire cycle. first one, swelling buds,...
Abstract The objective of this work was to evaluate the effects saline and water stresses on germination seeds stress development seedlings 'SCS437 Catarina' Passiflora edulis. were germinated paper moistened with NaCl PEG 6,000 solutions, at osmotic potentials 0.00, −0.25, −0.50, −0.75, −1.00, −2.00 MPa. produced exposed only NaCl. show tolerance up an potential −0.75 MPa, while present −0.50 MPa (10.96 mS cm−1).
Abstract: The objective of this work was to evaluate the production advanced seedlings sour passion fruit (Passiflora edulis Sims.) in pruning intensities at different volumes containers. experiment carried out a nursery, Pedras Grandes, Santa Catarina state. experimental design randomized block and treatments were arranged factorial scheme five (control from emission 2, 4, 6, 8 defined leaves) x 3 container (1.0; 1.7 3.6 liters), with three replications six plants per plot. height number...
Abstract: The objective of this work was to evaluate the number successive applications gibberellic acid (GA3), during autumn-winter period, for its effect on reduction flowering, in subsequent spring after periods low fruit load (off-year), 'Montenegrina' mandarin trees (Citrus deliciosa). Sequential at 40 mg L-1 GA3 were tested from one four times, 21-day intervals, beginning end May. experiment carried out a randomized complete block design, with treatments and control, replicates, plant...
The tangor cv. URSBRS Hada [Citrus unshiu Marc. à C. sinensis (L.) Osb.] produces late ripening fruits, the harvest is carried out from October to December in Rio Grande do Sul, Brazil. Little known about postharvest behavior of these thus aim this work evaluate effect storage temperature and rootstocks on fruit conservation. Fruits were harvested 16-year-old plants a commercial orchard Butiá, Brazil (30° 07â58â S, 51° 51â 22â W). After harvest, fruits treated with imazalil...
The passion fruit (Passiflora edulis Sims.) propagates by sexual reproduction and presents slow uneven seed germination. This work has the goal of identifying a temperature photoperiod that provide greater germination cultivar SCS 437 Catarina. We used an entirely randomized experimental design in 2 x 3 + 1 factorial: two temperatures (alternating between 20/30 ºC constant 25 ºC) three photoperiods (8/16 – 8 hours light 16 darkness; 12/12 12 absence light), for alternating temperature,...
