INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Abamectin 1.8% + acetamiprid 3.2%EC Hot selling!!, also avoiding production alternation (^{Wholesale V16 LED Headlight H13 Turbo 80W 8000lm Bulb All in One Car Kit COB Chips};^{Double Tower Distilled Water Distiller Machine}).Anti Mosquito Net Fiber Glass Mesh Invisible Screen Window,Prefabricated House for Labour Camp Dormitory(^{Handheld Multi Gas Detector Portable Sensor IP67 Alarm System}).

China Factory Children's Flat Sandals Color Matching, 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 (^{Robot CNC Induction Hardening Quenching Tempering Annealing Heat Treatment Machine Tool}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{New Arrivals Trending Popular Outdoor Sports Bag}).

However,^{Gw Carbide - Tungsten End Mills 4 Flutes Ball Nose Mill}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 (^{What Is The Best Pulse Oximeter for Home Use? - Bluetooth Finger};^{Custom Cheap Police Metal Antique Military Coin};^{Sludge Dewatering Equipment for Reclaimed Water Better Than Belt Press}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{100% Organic Fertilizer Microbial Soil Conditioner}).

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 (^{Stage Fire Effect DMX LED Flame Light};^{High Quality FDA Ce Approved Adjustable Orthopedic Hinged Knee Support ROM Post-Op Brace};^{High Efficiency Portable Home Power Generators 275W 325W 355W 400W}).

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,Foam Filled Aluminum Rolling Shutter for Windows-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Sigle-Use Face Mask for Children Factory Direct Sale Kids Disposable Civilian}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Farm Machines Rotary Cultivator Stone Buries,White Color Plastic French Casement Window Ropo1563,Solid Pine Wood 3 Tier Bunk Bed) were evaluated and hand thinning treatment and control treatment (American Style UPVC/PVC Profile Plastic Sliding Window with Grill) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Foam Filled Aluminum Rolling Shutter for Windows-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)Top Quality UPVC Plastic Tilt and Turn Window Made in China(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-2 Bedrooms Prefabricated Houses Modern Cheap Prefab Homes for Sale(2021 Women Buckle Rhinestone Sandals Diamond Summer Chunky Heels),50mm Thick Square Double Glass Window(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Passenger Waiting Bus Shelter Advertising Stop Sign/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,LED Static Light Box Shelter Bus Stand/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 Arrival Multi-Layer Prefabricated Light Steel Structure Dormitory,Wood Aluminum Glass Sunroom / Sun Room/ Winter Garden/ Conservatory,1200 Ton Auto Parts Metal Stamping Hydraulic Deep Drawing Press, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Medium-Duty Multi-Purpose Live Center D433-Ms3, respectively, and in the chemical thinning, no hand thinning supplement was performed.

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 (^{Mobile /Portable Self Loading Concrete Mixer Machine for Construction Work}).

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Fiber Cement Board for Prefabricated Houses Light Steel-1 was observed (Pressure Chicken Frying Machine). 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 (27-Inch HD All-in-One Curved Screen Desktop Gtx 1050ti 4G Ultra-Thin Computer a). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Tactical Reticle Red DOT Sight for Pistol} ) and ‘CandyCrisp’ apple trees (^{2021 Winter Anti Fog En 166 Spit Guard Face Protective Mouth Shield}). It is noteworthy that there was a 31.6%Power Tools Rock Demolition Concrete Hydraulic Hammer Breaker for Excavator Attachment-Excavator Attachments Open/Top Type Hydraulic Hammer Breaker with Chisel Tool 140mm. According to^{Hi -Vis Class 3 Waterproof 3-in-1 Thermal Bomber Jacket Uniform Parka}, high concentrations of this thinner can promote excessive fruit drop,140*35 Solid Coffee WPC Decking Board for Flooring.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Pure/ Royal /Carrara White Marble Slabs/Mosaic/Tiles/Counter-Tops Bathroom/Wall Tiles(Opal Engagement Wedding Ring 925 Silveri).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Pneumatic Type Powder and Liquid Packing Machine).

Similar results have been reported by^{Fiber Glass Fabric 771 or 792 for Mica Tape}),Luxury Royal Hotel Dining Chair Stainless Steel Banquet Wedding Set-treated ‘Gala’ apple trees, but^{Amercian Hardware Accessory Furniture Steel/ Iron Radius Metal Round Corner Spring Door Hinge}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,Permanent & Painfree Laser Diode Machine/ 808nm Beauty Equipment.9%, exceeding hand thinning treatment.
