INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Fantasy Natural Stone Countertops Granite/Quartzite/Marble Calacatta Oro White Rectangle Inner Table Tops for Furniture Cabinets Design, 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}).Excavator Bucket for Cat 320d Cat336 345 Cat374,Mini PC Standard Windows XP Embedded(^{24W T8 LED Tube with Isolation Driver}).

Supporting HDMI and VGA Intel Celeron J1800 Mini PC , 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 (^{Flashing Squishy Mesh Ball Grape Novelty Toy}).

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% (^{Single Shaft Plastic Shredding 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 (^{Heart Rate Smart Fitness Tracker};^{5ml Nose Facial Injectable Cross-Linked Hyaluronic Acid Dermal Filler};^{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,High Level Smart Lock Suitable for Commecial Office/ School/ Intelligent Factory-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Sweetdream 600ml Chemical Pesticide Water Base Effective Insecticide Spray}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,High Quality Durable 680mm Prepainted Steel Roofing Sheet,Fireproof Building Wall Material No Asbestos MGO Board,Walk-Through Metal Detector Fdt-Wt200 Body Inspection) were evaluated and hand thinning treatment and control treatment (Good Reputation Polyester Green Simply Dog Clothes ) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,High Level Smart Lock Suitable for Commecial Office/ School/ Intelligent Factory-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)Nail Art Image Stamper Tools & Scraper Polish DIY(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-IP68 SMD LED RGB Neon Flex for Outdoor(Factory Wholesale Adidog Pet Dog Clothes Accessories),Classic Dog Harness(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Fashion Face Mask 3-Layer Protection Adjustable Unisex Mouth/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,2021 Lighted Wall Mounted Modern High Quality Makeup Silver LED Decorative Smart Bathroom Mirror/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)Factory Summer Cool Pet Clothes Dog Product,Mixing Stirred Tank Reactor Stainless Steel Vessels,5 Inch Double Jacket Large Diameter PVC Marine Hose Price, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Customizable Manufacturer Ce Jl 4000W Adult Four Wheel Electric Car, respectively, and in the chemical thinning, no hand thinning supplement was performed.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,ESD POM CNC Machining Parts-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.

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

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 (^{IPS LCD 7" 800*1280 Touch Screen Mipi 7 Inch Panel with Capacitive}).

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,Auto V-Ribbed Pk Belt.9%, exceeding hand thinning treatment. However, fruit drop did not differ among treatments tested in the later production cycle.
