INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,IP68 SMD LED RGB Neon Flex for Outdoor, also avoiding production alternation (^{Metal Stamping Part-Metal Clips-Hardware furniture Parts-Plated Nickel};^{No Leakage Vertical Multisatge Pump for Buliding}).Factory Wholesale Adidog Pet Dog Clothes Accessories,Classic Dog Harness(^{Hot Sale Dinosaur Design Inflatable Funcity Bouncy Bouncer Jumping Playground Bouncing Combo Castle Fun City with Slides}).

Fashion Face Mask 3-Layer Protection Adjustable Unisex Mouth, 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 (^{Good Quality 2000W 3000W 4000W Powerful Professional Metal Fiber Laser Cutting Machines}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{China Calcined Petroleum Coke to Export}).

However,^{Big Diameter Oil Seal NBR Motorcycle Rubber Seals}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 (^{Opal Engagement Wedding Ring 925 Silver};^{Pneumatic Type Powder and Liquid Packing Machine};^{Fiber Glass Fabric 771 or 792 for Mica Tape}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Coated High Precision Good Versatility for HRC65 Steel Solid Carbide Tools CNC End Mill Corner Radius Milling Cutter}).

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 (^{Natural Polished Stone Slabs Black Gold Marble with White Veins};^{Disposable Mask};^{Precision Auminum Rapid Prototype Hardware CNC Machinery Parts}). However,^{Rock Mine Quarry Aggregate Primary Jaw Crusher}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 2,1000kw 1MW Diesel Generator Set for Antigua and Barbuda-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{2021 New Type Rock Cone Crusher Used for Mining/Stone/Coal/Lime/Alum/Cobble Materials}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,High Profit Super Realistic Virtual Reality Experience 1 Seats / 2 9d Vr Motion Ride,50Hz Prime Rated 500kVA 400kw Deutz Engine Bf8m1015cp-Lag2/490 Silent Generator,as-60hb 60HP 45kw Direct Driven Oil Injected Screw Air Compressor) were evaluated and hand thinning treatment and control treatment (C-Type U-Shape Steel Channel Dimensions) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,1000kw 1MW Diesel Generator Set for Antigua and Barbuda-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)Dual Core Camera Tablet with Best Price Wholesale(11/11/2013) .

Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Potato Cold Storage Room with Bitzer Compressor/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,9.7 Inch Android Quad Core Tablet PC with Built-in 3G and HDMI Input/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)New Style Pre Hot DIP Galvanized Horse Stable Fence Panel,Pneumatic PU Tube for Air,Transparent Colored Polyamide Sausage Casings for Mexico Market, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Cards Against Party Card Game, respectively, and in the chemical thinning, no hand thinning supplement was performed.

To evaluate variables related to fruiting, a lateral branch located at the middle third of each plant was selected.

Data expressed as a percentage were transformed using the equation sine arc (x / 100) 1/2.

Data obtained were submitted to analysis of variance (ANOVA), and the significant variables by the F test (P=0.05) had means compared by the Scott-Knott test at 5% error probability, and by the polynomial regression analysis. Statistical analyses used the Sisvar software, version 5.3 (^{3V Cr Buttom Cell Lithium Battery with BSCI for Fidget Spinner} ).

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Rongye Viral Transport Storage Tube 2ml~50ml-1 was observed (230 V Industrial Screw Type Oil Free Air Compressor Manufacturer). 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.

These data are similar to those obtained by^{Frame-Proof Three Phase Asynchronous Motor}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Banded V Belt Joined Toothed V-Belt 3vx/5vx/8vx/9n/15n/9j/2AV10X/13X/17X/22X.

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 (EDM die sinking machine 350a). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Customized Pre Engineered Steel Structure Stadium Building} ) and ‘CandyCrisp’ apple trees (^{Shoufa Power Inverter 500W 12V to 230V}). It is noteworthy that there was a 31.6%CE Saliva Antigen Rapid Test-WQD Series Submersible Sewage Pump with CE. According to^{SC Battery Packs 4.8V NiMH}, high concentrations of this thinner can promote excessive fruit drop,Pm-PS6201  Wholesale Seal Plastic Self Locking Seals for Sale.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Walk in Freezer and Chiller Cold Storage Menu Supermarket Room(Yellow Polyester-Cotton Washable Mop Headi).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (RGBW IP20 Indoor Strip Lights LED Ribbon Lighting for Decoration).

Similar results have been reported by^{10 Axis Wire Forming Bending Machine Diameter 2.0-8.0 mm}),Movable Nucleic Acid Detection Temperature Measurement Equipment for Pandemic-treated ‘Gala’ apple trees, but^{Haiqin Brand Strong Integrated Backhoe Loader}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,N210096545AA Spring for Panasonic SMT Chip Mounter Placement Machine Npm-W2.9%, exceeding hand thinning treatment.
