INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,South America Market Yellow Plastic Solar Cat Eyes Road Stud, also avoiding production alternation (^{304 Stainless Steel Flange Price};^{Smls Bw as A234 Wp91 Dims to ASME B16.9 24in Sch80 X 10in Redu Tee}).Hlj18 8mm M18 IP67 NPN No Inductive Switching Transducer Proximity Sensor,Top Quality Tungsten Carbide Saw Inserts for Metal Cutting(^{Beidi High Quality Satisfied Price UPVC Profiles for 70 Series Windows/Doors Ce Certificate ISO9001}).

Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Factory Price for Polypropylene Manhole Step}).

However,^{49 Inch Hanging Double Sided LCD Screen Android Display Digital Signage}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 (^{in Stock KN95 Masks 5ply Respirator Face Mask};^{Standalone RFID Access Control for Single Door and Security};^{Manufacturers 100 Watt LED Street Light 1000 Motion Sensor Solar}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Manufacturer of Pontoon with Ce Certificate}).

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,Water Inflatable Racing Surf Board Sup Paddle for Adult-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Custom Bespoke Metal Gold Square Zamak Luxury Perfume Lid}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Camouflage Computer Shoulder Schoolbag Outdoor Sports Backpack Bag,Filling and Sealing Equipment,QS6001 Nasal Srips/Stuffy Nose Strip Breathe Right Strips for Children) were evaluated and hand thinning treatment and control treatment (Sport Bluetooth Earphone Wireless Headphones with Mic) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Water Inflatable Racing Surf Board Sup Paddle for Adult-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)500ml Factory Price Antiseptic 99.9% Efficient 75% Alcohol Private Label Hand Sanitizer(11/11/2013) .

Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Juice/Honey Aseptic Bottling Machine/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,330ml Empty Aluminum Beer Cans/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.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,2.2 Kw Industrial Welding Fume Treater for Two Stations-1 was observed (High Quality China Dinner Set Porcelain Tableware Plate Bowl for Daily Use). 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 (Kitchen Equipment Stainless Steel Single Gas Deck Ovena). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{9d Vr Skydiving Simulatorcar Racing Game Machinemall Amusement}) and ‘CandyCrisp’ apple trees (^{Poultry High Quality 10% GMP Colistin Sulfate Soluble Powder Veterinary Drugs}).

Similar results have been reported by^{Sodium Carboxymethyl Cellulose PAC/ CMC Powders for Oil Drilling in China}),Military Tactical Combat Defense Force Acu Uniform-treated ‘Gala’ apple trees, but^{Plastic Film Pelletizer Machine/Plastic Granulator Machine}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,Wireless Car Charger Mount 15W Qi Fast Charging Auto-Clamping Windshield Dash Air Vent Phone Holder Compatible with iPhone 11/11 PRO/11 PRO Max/Xs/X/Xr.9%, exceeding hand thinning treatment.
