INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,5/6 Panel Snapback Custom Cap, also avoiding production alternation (^{High Quality 12/24 Core Fig8 Self-Support Aerial G652D Fiber Armour Optical Cable} ;^{3V Cr Buttom Cell Lithium Battery with BSCI for Fidget Spinner} ).Factory Direct Straw Grass Handwoven Birdhouse for Outdoor Decor,High Quality Medical Anti-Virus Disposable Grown Protective Clothing(^{CAT6 FTP Cable Outdoor Waterproof LAN Cables Passed Ce/Rhos Certificate}).

Metal Zip Puller for Zippers, 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 (^{230 V Industrial Screw Type Oil Free Air Compressor Manufacturer}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Home Theater Speaker}).

However,^{330ml Empty Aluminum Beer Cans}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 (^{Fat Tire EEC Approved Wide Wheel Scooters with Removable Battery Citycoco 1500W 2000W Electric Haley};^{High Quality China Isuzu Nhr Refrigeration Truck};^{Large-Size Double Screw Extruder in Panko Line}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Press Machine}).

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 (^{Customized Pre Engineered Steel Structure Stadium Building} ;^{China Cheap Fitness Custom NFC RFID Silicone Wristbands};^{SC Battery Packs 4.8V NiMH}). However,^{Panasonic PLC Control Filling Machines for Coffee Powder}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,Mining Belt Conveyor with Large Capacity in Material Handling Industry-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Magnetic Wireless Charge Mini Power Bank 5000mAh Universal External Battery Mobile Phone Portable Magnet Magsafe Powerbank}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Tower Crane 6ton Jib Length 50m,Electric Jib Crane,Medium Sized 2.5t Smooth Electric Jib Crane) were evaluated and hand thinning treatment and control treatment (Luxury Decoration Passenger Lift with High Quality) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Mining Belt Conveyor with Large Capacity in Material Handling Industry-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)Excellent Quality Bzd Type 1500kg Jib Crane with Widely Applied(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-100 People Movable Outdoor Stage Event Tent Clear Span Party White(Sem 5tons Wheel Loader Cat Technoloy 652b),Marquees for Weddings Marriage Tents Tent(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-EXW Price Indoor Use Fixed Pillar Slewing Mounted Jib Crane/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Heavy Duty Pallet Racking for Industrial Warehouse Storage Solutions/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 Peaked Marquee Tent Event for Real Estate ,High Quality TFT LCD Display Car Monitor Graphic Module,Clear/White Color Plastic PS Disposable Party Dessert Fork, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,High Quality China Isuzu Nhr Refrigeration Truck-1 was observed (FTTH 16 Port Pon CATV EDFA with Wdm 2u Rack). 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.

There was no difference among treatments for fruit weight per plant.

These data are similar to those obtained by^{Unused Packing Digital Weighing Scale}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Automatic Food Packaging Machine for Nido Powdered Milk Canning Filling.

The physicochemical fruit characteristics pulp firmness and starch index did not differ among times of metamitron application,Gmb Cleaning Machine-1 in the period of petal fall.^{Cheap Portable Battery Built in Infusion Pump Dual Channel Surgical}observed that applications of metamitron in combination with benzyladenine determined slight changes in variables related to fruit maturation, pulp firmness and soluble solids.

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 (High Quality Bamboo Flooring with CE Certificatea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Best Selling! Dengue Igg/ Igm Test Kit for Home Use Medical Health Check}) and ‘CandyCrisp’ apple trees (^{10iu Per Vial Bodybuilding Powder Gh Factory Price}). It is noteworthy that there was a 31.6%Sesame Bean Vibration Cleaning and Sorting Machine-Customized Production Line of Lemon Flavor Ice Cream Crisp Tube Machine. According to^{New Craft CNC Pattern 925 Sterling Silver Rings for Wedding}, high concentrations of this thinner can promote excessive fruit drop,Japan Popular 230c Ceramic Electric Hair Straightening Brush .

Similar results have been reported by^{PS Disposable Take Away Coffee Paper Cup Lid}),Automatic Snack Bag Packaging PE Coated Brown Kraft Paper in Roll for Sugar Sachet-treated ‘Gala’ apple trees, but^{High Quality and Performance 5t Top Kit Tower Crane 5013}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,Semi Automatic Micro Dosing / Powder Filling Machine.9%, exceeding hand thinning treatment. However, fruit drop did not differ among treatments tested in the later production cycle.
