INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,High Quality Wholesale Price Ultra Thin LED Panel/Ceiling Light, also avoiding production alternation (^{Health Food};^{Manufacture High Quality Comb Cotton Multiple Pique Knitted Fabric for Shirt Garment}).LED Solar Landscape Lamps All-in-One/Integrated Street Garden Wall Light,Sc 8 Port Fiber Optic Terminal Box(^{Epistar LED Flood Light outdoor 50W Floodlight}).

Customized Copper Cable Lugs Crimp Type Terminal, fruit set from year to year is very variable, so that the evaluation of the need and intensity of thinning can only be performed after fertilization, making chemical thinning at flowering a practice of great risk for producers (^{Bonovo Super V Series V61 Bucket Teeth Tooth Tip Nail Adapter Adaptor V61-K for Excavator Digger Trackhoe}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Small Wilfley Shaking Table for Sand}).

However,^{Geosynthetic Warp Knitting PVC Coated Fiberglass Polyester Geogrid}highlight the low availability of thinning products, especially in areas under strict regulatory controls for the registration of new molecules, requiring the development of new environmentally safe and highly efficient products, such as benzyladenine.

Herbicide metamitron is an inhibitor of photosystem II, belonging to triazinone chemical group, which has recently been reported as efficient product in the thinning of apple crops (^{QS6001 Nasal Srips/Stuffy Nose Strip Breathe Right Strips for Children};^{10X30m Cheap Party Tent in South Asia} ;^{D699 Brake Pad for Buick Cadillac Chevrolet Oldsmobile Pontiac}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{50t/D Rice Plant Processing Machine Whitener}).

The decrease in plant fructification as well as the increase in mean fresh fruit weight is proportional to the increase in the metamitron concentration applied (^{SLES Sodium Lauryl Ether Sulfate};^{Gold Trommel Screener for Sale Mining Machine};^{Disposable Non-Woven FFP2 Particle Filtering Kn 95 Folding Face Mask}).

MATERIAL AND METHODS

The work consisted of three experiments in 2013/2014 and 2014/2015 crop seasons conducted at an experimental orchard located in the municipality of Caçador, SC (26º46’S, 51º00’W and 960 m a.s.l.).

In experiment 1, 12-year-old apple trees Baronesa / M-26 cultivar were used at planting density of 2,R134A T3 Condition Air Cooled Packaged Rooftop HVAC Unit-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Hip Hop Jewelry 925 Sterling Silver Pave Diamond Ring for Women}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,High Brightness150W LED Moving Head Spot,High Quality Audio Cable Factory RCA ,RF-650 Pet) were evaluated and hand thinning treatment and control treatment (Africa customer favorite Shacman 6X4 Trailer Head Truck Tractor) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,R134A T3 Condition Air Cooled Packaged Rooftop HVAC Unit-1, and six metamitron concentrations (0 mg L -1, 350 mg L -1, 700 mg L-1, 1050 mg L-1, 1400 mg L-1 and 1750 mg L-1)restaurant Coffee Shop Decorative Lighting Blue Aluminum Pendant Lamp(11/11/2013) .

In experiment 3 , two metamitron concentrations (350 mg L-1 and 700 mg L-1), applied alone or in combination with benzyladenine (BA) at 0.8 mg L-P6 Indoor Advertising LED Display(Full Color P20 Transparent LED Display),Damask Uphostery Polyester Curtains and Sofa Cloth 300cm(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Manufacturer SPFS/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,High Quality Speed Single and Double Color Injection Model 8K 2.1V 48gbps HDMI Cable/01/2013. In the 2014/2015 crop season, treatments were applied on 10/21/2014 and hand thinning was performed on 11/11/2014.

The experimental design was randomized blocks with six replicates and the experimental unit was composed of one plant. Commercial product Goltix® 700SC WG (70% i.a.) was used as source of metamitron, and commercial product MaxCel® (2% i.a.) was used as source of benzyladenia (BA).

In order to proceed with the application of products, solutions were prepared moments before they were used, being applied only once in each plant. Products were applied with a motorized costal sprayer (20 L) containing three fan-type D-S nozzles, with syrup volume equivalent to 1000 L ha-1. The diameter (mm)O Neck Long Sleeve Shirts Fitness Thumb Hole Sweatshirt,Portable VCD player,Video Clickwhell for iPod, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Double Circuit Transmission Steel Tube Pole Tower-1 was observed (Good Quality 10 Chutes Color Sorter). Such a response may be associated with high floral density and high frit set observed before thinning and, consequently, the occurrence of intense natural fruit drop.

Evaluating the use of metamitron at different concentrations in ‘Baronesa’ apple trees, a direct proportional relationship was observed between concentration of this phytorregulator and fruit drop (Mixed Colors Grid Design Modern Flat Wooden Texture Laminating Flooring Easy to Install and Cleana). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Eco-Rail Mounted Mobile Dust-Trap Hopper Dust Proof}) and ‘CandyCrisp’ apple trees (^{Factory Concrete Formwork Shuttering/Marine Plywood/Construction Waterproof Film Faced Plywood for Building Use}).

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Plastic Cosmetic Soft Tube for Sun Cream 20g(Inch Round 22W LED Panel Light with CEi).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Tk-570 Consumables Compatible Color Laser Copier Toner Cartridge for KYOCERA).

Similar results have been reported by^{100ml /200ml Shampoo and Conditioner Square Lotion Bottle for Plastic Packaging}),PA System Three-Way Touring Line Array Speaker-treated ‘Gala’ apple trees, but^{Dedi 32 Inch Wall-Mount Advertising Screen LCD Display for Indoor}reported great variability in flowering density in response to metamitron use according to cultivar and times of application. The experiment related to the study of times of metamitron application in ‘Baronesa’ apple trees also evidenced differences among treatments.

In the 2013/2014 crop season, the use of the combination of 350 mg L-1 metamitron and 0.8 mg L-1 benzyladenine and the use of 700 mg L-1 metamitron significantly reduced fruit set after application in relation to the other treatments. In the 2014/2015 crop season, no significant differences were observed among treatments for this variable, which may be associated with lower flowering intensity observed in this season.

In the 2013/2014 crop season, all treatments with metamitron, regardless of concentration adopted, alone or combined with benzyladenine,12inches PA Speaker Audio Component.9%, exceeding hand thinning treatment. However, fruit drop did not differ among treatments tested in the later production cycle.
