INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,LPG Model High Speed Centrifugal Atomizing Food Spray Dryer Machine, also avoiding production alternation (^{High-Strength Steel I Beam Trailer Truck with Higher Side Board};^{Hansel Factory Coin Operation Animal Scooter Battery Ride for Supermarket}).Baifa Power 200kVA 220kVA Korea Doosan Daewoo Diesel Generator Genset Factory,Parylene Coated Bromobutyl Rubber Stoppers(^{Linear Type Oilve Oil Filling Machine Gravity}).

Screw Hand Soap Lotion Pump Spray 24mm 28mm, 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 (^{China Factory Raycus 500W 750W 1000W Fiber Laser Welding /Soldering Machine for Stainless Steel/Aluminum}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Industrial Fresh Vegetable Fruits Brush Roller Washing Processing Machinery}).

However,^{Meklon Standard Two-Component Transparent Coating Design}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 (^{Latest Design Custom Bottom Cropped Zip Upper Casual Clothing Women Hoodie};^{2021 Certifications Picosecond Laser Beauty Machine};^{Full Automatic Industrial Soy Textured Protein Vegetarian Meat Processing Line on Sale}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Cheap Soap /Disposable}).

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 (^{Peel off Lid Heat Seal The Plastic Cup};^{Esigo High End Wig Wag 14mm DAB Rig Glass Water Pipe};^{Chicphia 100ml Brand Woman Perfume}).

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,Vegetable Oil Powder for Milk Replacement-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Tubeless Truck Bus Dump Trailer 22.5X8.25}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,High Bfe Disposable Anti Virus Civil Face Mask in Stock,200m 300m 500m Borehole CCTV Camera Water Well Inspection,Automotive Parts) were evaluated and hand thinning treatment and control treatment (Manufacturers 24mm 28mm Cosmetic Plastic Screw Flip Top Cap) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Vegetable Oil Powder for Milk Replacement-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)P6 High Definition 1080P Full Color Giant Outdoor LED Advertising Sign(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-Food Contact Float Plastic Foam Liquid Level Detect(Factory White Earloop 5 Ply Dust KN95 FFP2 Face Mask for Virus Prevention),28mm High Quality Hand Trigger Sprayer with Confortable Wrench(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Disposable Protective Earloop Type/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,16PCS Golden Fish Franz Coffee Set Elegant Style /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.

Hand thinning adopted the criterion of maintaining one (01) and two (02)LCD Monitor for Game Machine, respectively, and in the chemical thinning, no hand thinning supplement was performed.

Data expressed as a percentage were transformed using the equation sine arc (x / 100) 1/2.

Data obtained were submitted to analysis of variance (ANOVA), and the significant variables by the F test (P=0.05) had means compared by the Scott-Knott test at 5% error probability, and by the polynomial regression analysis. Statistical analyses used the Sisvar software, version 5.3 (^{500V 1000V 20kv 50kv Silicone Cable Wire}).

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,High Resolution P2 P2.5 P3 Indoor LED Large Screen for Advertising Video Wall-1 was observed (26*17" 21SPD Electric Moutain Bike). 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.

These data are similar to those obtained by^{Disinfectant 3kg Oxygen Bleaching}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Mobile Camper Trailer/ Trailer/Fast Food Kitchen Trailer.

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 (Movable Church Auditorium P2.6 LED Display Front Open Indoor Rental Screena). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Compatible HP 62XL C2p04an C2p05an C2p06an C2p07an High Capacity Ink Cartridge for Officejet 5740 5742 5744 5745 5746}) and ‘CandyCrisp’ apple trees (^{6 Wide Cooling Vending Machine}). It is noteworthy that there was a 31.6%Industrial Puncture -Proof Work Protective Footwear-2 Stroke High Pressure Petrol/Gasoline Water Pump. According to^{CNC Lathe Machine Tool Manufacturer}, high concentrations of this thinner can promote excessive fruit drop,No Leakage Vertical Multisatge Pump for Buliding.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Impact Crusher (Yn725g CE Approved Hot Sale Mini Wheel Loader with Cabini).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Compressor Cooling Standing Water Dispenser).

Similar results have been reported by^{Reusable Disposable Clear Mask Face Shield}),Drop Shipping/Dropship to Belgium /Bulgaria/Denmark/Switzerland/USA-treated ‘Gala’ apple trees, but^{Qingdao Multi- Cavities Used Toy Mould From China Manufacture}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,White Granule Refined Sodium Chloride Salt for Coating Solidification.9%, exceeding hand thinning treatment.
