INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Copper Plating Chrome-Plating Metal Wire Bathroom Hanging Shower Caddy, also avoiding production alternation (^{Roof Ventilator Aluminium Alloy with Fluorinecarbon Polyester Coated 600mm};^{Ouch Screen Car DVD Player for Ford Explorer GPS Navigation System}).High Strength Steel Welding Wire Er100s-G 15kg /D300 Spool,Makute Electric Planer 82mm Wood Working Cutting Tools(^{2.5mm 0.098inch AISI440c Stainless Steel Balls for Household Appliances 0.063G}).

Ultra -Low Temperature Strong Cooling Glycol Small Water Chiller for Food, 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 (^{Fs6057 Lift or Flush ABS Black Pull Handle with Single Hole Mount for Cabinet}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Full Automatic Glass Bottle Pet Beer/Carbonated Drink/Soda Water/Soft Water/Carbonated Juice/Beverage Bottling/Filling Machine}).

However,^{Chinese Factory 3-Ply Disposable Non Woven Earloop Face Mask}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 (^{Weho Nes Series 350W 15A 24V AC DC Power Supply};^{Full Nutrtion Mixed Roasted Bean Dried Fruits Snacks Bulk Packing};^{CE Sauer System CS Streamlined Loader with Implement}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{SMS/SMMS Disposable Eo-Sterilized Surgical Gown Pack}).

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 (^{Fabric Reinforced Rubber Matting Cloth Cotton Nylon Insertion Mat};^{Buckwheat Cassia Seed Chia Cleaner Manufacturer};^{Potato Cold Storage Room with Bitzer Compressor}). However,^{PE Pressure Pipe Production Line High Ring Stiffness Extrusion}point out the possibility of excessive fruit drop depending on the concentration and application stage of this plant growth regulator.

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,Molded 3D Mats EVA Car Mat Rubber Floor-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Touch Screen Payment Kioskkiosk Barcode Scannerkiosk Media Playerdigital Signage Advertising Player Digital}).

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Molded 3D Mats EVA Car Mat Rubber Floor-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)PVC Foam Board with Hard Surface for Kitchen Cabinets(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-Hot Sale Good Quality Bedroom Decoration Wax Waterproof Parquet Laminate Flooring(Modern Style Wooden Texture Laminating Floor AC3 AC4 HDF Tile PVC Flooring),Mixed Colors Grid Design Modern Flat Wooden Texture Laminating Flooring Easy to Install and Clean(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Wear Resistance Customized UHMWPE Hpde PE 1000 500 Sheet/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Water-Saved Air Bubble Vegetable Fruit Washing Machine/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)High Temperature Resistance TPV,Customized White Plastic ABS / POM CNC Machining Parts,Long Life Carbide Trenching Tools Cutter Pick Bit Kt C24, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Polymer Waterproof Mortar Remarkable Waterproofing Material, respectively, and in the chemical thinning, no hand thinning supplement was performed.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Hot Selling Durable Handscraped Brazilian Cherry Wood Parquet/Brazilian Jatoba Parquet Floor -1 was observed (Trailer Parts Use Sf Mechanical Suspension). 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 (12inches PA Speaker Audio Componenta). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Best Design Steel Structure Building Metal Shed Prefabricated Large Span Warehouse with Long Life}) and ‘CandyCrisp’ apple trees (^{Waste Plastic PE/PP Film Granulator Machine}). It is noteworthy that there was a 31.6%28mm High Quality Hand Trigger Sprayer with Confortable Wrench-Disposable Protective Earloop Type. According to^{3 Pin Connector Cable Wire Vertical Injection Molding Machine 35t}, high concentrations of this thinner can promote excessive fruit drop,16PCS Golden Fish Franz Coffee Set Elegant Style .

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Rechargeable Hearing Aid Mini Invisible Amplifier Cic(Motorcycle Oil Seal Kit for YAMAHA Ybr125i).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (HDPE 100ml Spray Bottle Plastic).

Similar results have been reported by^{Hydraulic Dock Leveler for Loading and Unloading}),Steel Manual-treated ‘Gala’ apple trees, but^{Graphite Electrode for Steel Smelting}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,ADSS Opgw Optical Fiber Cable G652D 48cores Fibra Optica.9%, exceeding hand thinning treatment.
