INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,100%Polyester Ruana Tie Dye Chiffon Poncho/Ruana/Warp/Cape, also avoiding production alternation (^{Bonny Wzy28-8c 28 Ton Hydraulic Material Handler with Crawler Crane};^{High Profit Super Realistic Virtual Reality Experience 1 Seats / 2 9d Vr Motion Ride}).5mm/0.3mm Mirror Aluminum Composite Panel for Indicator Board,Eboat Times O10 Hemp Oil Vape Pen Cbd Vaporizer Disposable E-Cigarette(^{Bloom Tech} ).

90-100W Reci W2 Laser Tube with 1200mm Length, 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 (^{Refrigerator Parts AC Motor Start Capacitor 10UF 250VAC}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Foot Switch Surgical Power Device}).

However,^{Facial Sculpture Dermal Filler 5ml Injection Hyaluronic}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 (^{Sunkea Wholesale Price Takeaway Packaging Pulp Lunch Box for Food};^{Jarrow Formulas};^{Carbon Fiber Motorcycle Part Windshield for Kawasaki}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{1 Piece Forged Wheel Alloy Rims Racing with Brushed and Black Powder Coatings}).

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 (^{Smls Bw as A234 Wp91 Dims to ASME B16.9 24in Sch80 X 10in Redu Tee};^{Liberiahome and Conventional Fire Alarm Control Panel};^{Beidi High Quality Satisfied Price UPVC Profiles for 70 Series Windows/Doors Ce Certificate ISO9001}).

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,Light Commercial Peck Fly & Rear Delt Multi Function Gym Equipment-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Feiyang Kvg Double 12inch Professional Big Power Speaker System with Karaoke 200W E244}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,0.6/1kv PVC Insulated Sheathed Low Voltage Power Cable,Metalized Pet Decorative Film for Gift Flower Packing,HTC System Concrete Metal Segment Grinding Diamonds) were evaluated and hand thinning treatment and control treatment (Wnq Brand Multi Function Bench Home Gym Equipment) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Light Commercial Peck Fly & Rear Delt Multi Function Gym Equipment-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)Triangle Cheap Safety Cat Eye Plastic Reflex Reflector Kc204(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-High Quality Color Coating Glass Perfume Bottle by China Manufacturer(8mm Dibond Place Aluminum Composite Panel Sheet),6m Diameter Igloo Large Geodesic Dome Tent for Outdoor Activities(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-High Quality Polyester Pre Efficiency Air Filter for Spray Booth Filtration/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Cosmetic Empty 200ml Plastic Pet Bottle with Perfume Mist Sprayer/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 Quality Pendoo X88 Z8350 Mini PC Media Market Window 10 Smart TV Box Intel,High Polishing DIN Aluminium Locating Block Set,for Chery A3 Car DVD GPS Bluetooh Video Navigation System, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Education Training Advanced PVC Human Urinary System Model Anatomical-1 was observed (Ceramic Fiber Insulation Blanket 1400c for Forges). 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 (Natural Dry Sweet Paprika Granules Powdera). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Automatic New Snack Cream Sandwich Biscuit Machine with Packaging Sandwiching Making}) and ‘CandyCrisp’ apple trees (^{Polyester Chenille Hotel Contract Decorative Upholstery Sofa Fabric}). It is noteworthy that there was a 31.6%Art Paint Spray Ironlak Graffiti-Customized Design Canopy Promotion Gift Umbrellas Wine Bottle Outdoor Rain Folding Umbrella.

Similar results have been reported by^{35L Medical Oxygen Breathing Bag} ),Kitchen Equipment Ice Cream Machine Coffee Making Food Cart for Sale-treated ‘Gala’ apple trees, but^{Deep R2 Rice Paddy Tractor Tyre 28L-26}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.
