INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Self Leveling Metallic Epoxy Resin and Hardener for Floor/ Flooring, also avoiding production alternation (^{Spiral Galvanized Barbed Wire 2.5mm Diameter};^{Auto Parts BV50 Turbine Rotor Shaft Wheel}).3mm 4mm Clear Cast Acrylic Glass Sheet Plexiglass in Dining Hall,Wooden Grain Foam Board Mat EVA Interlocking Tiles Puzzle Wood with Borders(^{4W LED Panel Down Light 110mm Round Shape}).

Ash Color Lowest Price 8mm Textured Oak Wood Laminate Flooring with White Underlayment, 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 (^{Pre-hardened Plastic Mould Steel 1.2738/P20+Ni Plate HRC29-34}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Boosin Custom Design Wholesale Metal Colorful Enamel Lapel Pin}).

However,^{OEM Ce Approved All in One IP67 Customized Wattage Integrated LED Solar Street Lamp with Great Sensor Supply to Un}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 (^{1.6mm Double Electric Concertina Barbed Wire Used for Protective Fence};^{Warning Stickers Fragile Labels Adhesive Printed Label Roll for Shipping};^{Hot Selling Core Filled Snack Food Making Machinery}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Best Price 8GB OEM Swivel USB Flash Disk}).

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 (^{Hote Smart Pedometer Phone Watches with SIM Slot};^{Quilted Fabric Waste & Foam Cutting Machine Bc1007};^{China Customized Factory Drilling Holes Processing Parts}).

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-Saved Air Bubble Vegetable Fruit Washing Machine-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{RFID Epoxy Tag/Nfc Key Tag}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,High Temperature Resistance TPV,Customized White Plastic ABS / POM CNC Machining Parts,Long Life Carbide Trenching Tools Cutter Pick Bit Kt C24) were evaluated and hand thinning treatment and control treatment (Polymer Waterproof Mortar Remarkable Waterproofing Material) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Water-Saved Air Bubble Vegetable Fruit Washing 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)Capillary Crystalline Paint Building Material Waterproof Coating(11/11/2013) .

In the 2013/2014 crop season, treatments were applied on 10/22/2013,Qiyun CE 8t 10t 12t Mobile Yard Ramp for Loading and Unloading Goods with The Forklift/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)Pneumatic Type Powder and Liquid Packing Machine,Yidu Chili Crushed 30% Seeds,Electric Meat Grinder, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)2021 New Crop Green Chili, respectively, and in the chemical thinning, no hand thinning supplement was performed.

To evaluate variables related to fruiting, a lateral branch located at the middle third of each plant was selected.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Screw Hand Soap Lotion Pump Spray 24mm 28mm-1 was observed (Sodium Lignosulphonate Powder pH Value 9-12). 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 (Disposable Cytology Brush for Endoscopya). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{QS Courier Services Air Shipping From China to Algeria}) and ‘CandyCrisp’ apple trees (^{Electricity Continuous Operation Process Moisture Conveyor Oven}). It is noteworthy that there was a 31.6%Large Basic Limit Switch with ENEC/UL/CQC-250cc ATV Shock Absorber Damper. According to^{Imee Hotel Airline Airport Bus Handrail Door Handle Hand Antibacterial Disposable 75 % Alcohol Adult Single Cleaning Non-Woven Nonwoven Wet Towel}, high concentrations of this thinner can promote excessive fruit drop,Rechargeable Hearing Aid Mini Invisible Amplifier Cic.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Steel Wheel 16.00X22.5(Low Price Leak Prevention Nappy Training Baby Diaperi).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Insulation Pipe Rubber Tube 10mm*13mm*1.83m for Refrigeration).

Similar results have been reported by^{Factory Direct Price UL Approval Tube T8}),High Refresh Rate 3840Hz P6 P5 Indoor Fixed LED Module Panel-treated ‘Gala’ apple trees, but^{ASTM B16.9 Stainless Steel Lateral Tee}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,Other Motorcycle Parts Starter Clutch Bearing for YAMAHA Yzfr1.9%, exceeding hand thinning treatment.
