INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Headlight Lamp Assembly Auto Car Light for 2021 New Ford Mondeo, also avoiding production alternation (^{Rib 360 Inflatable Boat 12FT Full Welded Aluminum Hull Fishing Speed Skiff for Sale};^{China Fashion Sports Shoulder Handle Travel Backpack Bag}).China Professional Manufacturer 8 Tons Stationary Tower Crane Qtz100 ,Manufacturer Wholesale Jewellery 18K Gold Plated Necklace Cable Chain with Flower Embossed for Jewelry Craft Design DIY(^{24W T8 LED Tube with Isolation Driver}).

Ladies Fashion Jewelry Stainless Steel Jewellery Cable Chain Embossed 1: 1 Necklace for Decoration Design, 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 (^{Colorful Agriculture Greenhouse Fishing Marine Landscape Polyethylene Polyester Polypropylene Polyamide Danline Polysteel Twisted Braided Rope Cord Twine}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Fashion Jacquard Mesh Fabric Blank Trucker Baseball Sport Caps}).

However,^{11r22.5 12r22.5 Mining Mix Pattern Radial Truck Tyre Heavy Duty TBR Tyres}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 (^{15kHz Long Distance Ultrasonic Transducer for 50m};^{China High Quality Disposable Baby Diaper Sleeping Style};^{2.0MP Hikvision 20X CMOS HD IP High Speed Dome CCTV Camera}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{New Design 8kw Home Solar Power System off Grid with Batteries}).

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 (^{Heart Rate Smart Fitness Tracker};^{Factory Sutures Surgical Hipretty Face Lift Thread FDA Approved};^{Silk Rose Artificial Flower Wedding Home Office Garden Decoration}).

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,LC/Upc to Sm Simplex G652D 2.0mm PVC Fiber Optic Patchcord-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{2 Piece Flanged Ends 1/2~12 Inch Ball Valve}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Inflatable Fishing Boat with Aluminum Floor,Ship Rubber Balloon,Whole Fly Fishing Rod 11FT 4PC 6/7wt Carbonfiber Switch) were evaluated and hand thinning treatment and control treatment (Innovative Waterproof Outdoor Walnut Color WPC Board Composite Decking) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,LC/Upc to Sm Simplex G652D 2.0mm PVC Fiber Optic Patchcord-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)Matchless Colourfast Technology Contemporary WPC Decking(11/11/2013) .

In the 2013/2014 crop season, treatments were applied on 10/22/2013,Manufacturer 11m High Q235 Steel Street Lighting Pole/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)5m,for Sale 4.2m Rib Boat with FRP Bottom,Custom Made Artificial Stone Solid Surface Bathroom Countertop, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)French 52 in Black Resin Stone Free Standing Corner Bath Tub, 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.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,1000kVA Diesel Power Silent Generator Set with Electric Perkins-1 was observed (Australia Standard Eucalyptus Plywood F17 Formwork to As6669 Construct Linyi). 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 (Mini Projector Moving Head 150W LED Light Spot Effect Stagea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Sn Pb Rosin Core Resin Flux Cored Tin Lead Wire Solder}) and ‘CandyCrisp’ apple trees (^{High Quality Spreader Mirror Face Roller}). It is noteworthy that there was a 31.6%Factory Wholesale Electric  Surfboard  with Good Price-Slanna 2021 Autumn Winter Sexyl Ladies High Waist Casual Hot Shorts Corduroy.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’330ml Empty Aluminum Beer Cans(Notification Telephone Number Temporary Parking Cardi).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (New Style Prototype LED Window Metal Dome Membrane Keyboard).

Similar results have been reported by^{The Factory Produces Aerosol Cans for Carrying Air Cleaning Agents}),GCP-12A 12heads Automatic Sweet Liquor Filling Line Machine-treated ‘Gala’ apple trees, but^{RS485 Cabinet Air Conditioner AC Power 500W}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,3000-4000bph Full Automatic Blowing Moulding Bottle Machine.9%, exceeding hand thinning treatment.
