INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,1000mAh One Time Use Power Bank Degradable Disposable Emergency Charger, also avoiding production alternation (^{AG -By007 Ce ISO Five Functions Electric Rehabilitation Hospital Bed};^{Eco-Friendly Gift Band Colorful Silicone Wristand for Christmas Day Bracelet} ).Popular High Quality Products Aluminum Ingots,Eco Bags Machines(^{Ce En Lpcb Vds Standalone Smoke Detector 10y}).

Best Seller of Casi Cored Wire Ca28si55, 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 (^{Era Piping Systems PPR Pipe Fitting Cross} ). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Mini Plastic Roller Shutter Slats for Tambour Door System}).

However,^{P2.604 mm Indoor 250*250mm SMD LED Module Panel Display}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 (^{Japan White Disposable Face Mask Elastic Ear Loop 3 Ply Breathable for Anti Dust Virus Pollen};^{Eco-Friendly Carbon-Free Ink-Free 58mm Thermal Small Ticket Printer Portable Mobile Phone Bluetooth Receipt};^{Tungsten Copper Alloy Plate}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Modern Style Swivel Ergonomic Lift Leather Executive Office Meeting Chair}).

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 (^{4 Pedal Bicyle for Person/Outdoor Bike Family Activity} ;^{Mink Brazilian Unprocessed Straight Human Hair Extensions};^{Roof Ventilator Aluminium Alloy with Fluorinecarbon Polyester Coated 600mm}).

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,Automatic Filling Milk Creamer Powder Coffee Packaging Machine-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{5-Pin Soldering DMX Cable Plug XLR Male Connector}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,65 Inch Brightness 3000nits Outdoor Digital Signage,Outdoor 10m 100W LED Solar Street Light with Lithium Battery,55 Inch 3X3 LED Backlight Indoor LCD Video Wall with Seamless Ultra Narrow Bezel Panel for Advertising Display) were evaluated and hand thinning treatment and control treatment (Outdoor Waterproof LED Solar Street Light 40W Split) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Automatic Filling Milk Creamer Powder Coffee Packaging Machine-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)46 Inch Outdoor Flood Standing Digital Monitor(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-30W(Creative LED Light),Manufacturers 100 Watt LED Street Light 1000 Motion Sensor Solar(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Qty6-15c Fully Automatic Concrete Block Making Machine for Sale/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,6m 30W High Power LED Intelligent Solar Street Lights/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,High Quality Desktop Spoon Injection Molding Machine-1 was observed (CE Sauer System CS Streamlined Loader with Implement). 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 (PVC Window Profiles Single Axis Copy Router Machinea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Professional and Best Seller Steel Structure Warehouse /Prefabricated Garage Shed}) and ‘CandyCrisp’ apple trees (^{Fuji Apple}).

Similar results have been reported by^{Best Design Steel Structure Building Metal Shed Prefabricated Large Span Warehouse with Long Life}),Tire Crushing Production Line Shredding-treated ‘Gala’ apple trees, but^{Medical Protective Coverall PP PE Non-Woven Suit Disposable}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.
