INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Self-Heating Pain Releif Patch , also avoiding production alternation (^{High Efficiency Portable Home Power Generators 275W 325W 355W 400W};^{Mermaid Plus Size Bridal Wedding Gown Luxury Pleated off-Shoulder Dress}).Hi -Vis Class 3 Waterproof 3-in-1 Thermal Bomber Jacket Uniform Parka,Prevent Wound Infection After Vaccination/I.

Home Hotel  Antibacterial  Sanitized  Microfiber Polyester  Quilts Comforters, 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 (^{Double Station High-Speed Extrusion Blow Molder} ). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Jacquard Rayon Fabric Textile for Women Shirt}).

However,^{Chinese Hot Pot Sauce Herb and Spices Dried Red Sichuan Pepper}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 (^{Mobile /Portable Self Loading Concrete Mixer Machine for Construction Work};^{Best Selling Various Type Water Bottle Plastic Bucket Manufacturing Blow Molding Machine};^{Pressure Chicken Frying Machine}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Hot Sales Factory Supplier 3ply Earloop Disposable Protective Face Mask}).

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 (^{My-A010g 128 Elements Wireless Linear Probe};^{Rolling Shutter / Hurricane};^{K4 Full-Auto Plastic Pet Blow Moulding Machine Blowing Mold Locking Uniform}).

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,K4 Full-Auto Plastic Pet Blow Moulding Machine Blowing Mold Locking Uniform-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Jiachen Double Float Jet Ski Dock for Wholesale}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Dissolved Air Flotation Equipment Daf Machine for Wastewater Treatment,500ml 75% Alcohol Disinfectant Antibacterial Liquid Disposable Hand Sanitizer Gel,Wholesale High Quality 250ml Tin Nice Beverage Drinking Can) were evaluated and hand thinning treatment and control treatment (15 New Jbl Powerful HiFi Home Theater Wireless Bluetooth PA Professional Karaoke Party Trolley Loud Audio Battery Speaker) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,K4 Full-Auto Plastic Pet Blow Moulding Machine Blowing Mold Locking Uniform-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)15kHz Long Distance Ultrasonic Transducer for 50m(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-Fully Stocked LC Single Mode Quad Plastic Fiber Optic Adapter(Beauty Product Extra Virgin Coconut Oil Softgel),Spiral Galvanized Barbed Wire 2.5mm Diameter(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-12*14 Twisted Wire High Tensile Barbed/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,1.6mm Double Electric Concertina Barbed Wire Used for Protective Fence/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)HDPE Geocell Factory Manufacturer,Textured & Smooth Honeycomb Structure Geocell with 50mm--200mm Cell Depth,120kn-120kn/High Tensile Strength Grid/Carbon Polymer Geogrid, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Aws A5.18 Er70s-6 MIG CO2 Gas-Shielded Filler Solid Welding Wires Size: 1.0mm-1 was observed (Airsoft Military Force Recon Tactical Vest). 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.

These data are similar to those obtained by^{Big Diameter Oil Seal NBR Motorcycle Rubber Seals}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Outdoor Stainless Steel Post Glass Railing Brushed Finish.

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 (Pneumatic Type Powder and Liquid Packing Machinea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Fiber Glass Fabric 771 or 792 for Mica Tape}) and ‘CandyCrisp’ apple trees (^{6n-Tnga1604    PCBN Carbide Inserts for Turning Tools Working Cast Iron Tnga}). It is noteworthy that there was a 31.6%Modern Balcony / Staircase Stainless Steel Cable Wire Rod Railing Design-Best Design Customized SMD 24W Ultra Slim Recessed LED Downlight. According to^{Tire Recycling Shredding Equipment for Sale/Tyre Sale}, high concentrations of this thinner can promote excessive fruit drop,L Smart Walk Treadmill Easy Foldable Homeuse Running Walking Machine.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Surgical Care Bandage Plaster of Paris(3V Cr Buttom Cell Lithium Battery with BSCI for Fidget Spinner i).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (CAT6 FTP Cable Outdoor Waterproof LAN Cables Passed Ce/Rhos Certificate).

Similar results have been reported by^{230 V Industrial Screw Type Oil Free Air Compressor Manufacturer}),7525 Air Diffuser Cooling Ventilator Fan Exhaust DC Blower-treated ‘Gala’ apple trees, but^{Ebola Medical Team Nigeria Clinic Container House}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,Cbf Explosion-Proof Motor Axial Ventilator Fan.9%, exceeding hand thinning treatment. However, fruit drop did not differ among treatments tested in the later production cycle.
