INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Co-Extrusion UPVC Profile for Window Doors Without Le Waterproof PVC Windows /UPVC Profile/Plastic, also avoiding production alternation (^{Reflective Safety Hi Vis Workwear};^{Military Army Ceramic Hard Armor Bulletproof Ballistic Plate}).Plastic Textile Yarn Dyeing Bobbin,Metal Sheet Pipe CNC Laser Cutting Engraving Machine in Agricultural(^{Portable Slimming Machine Velashape Weight Lose for Cellulite Reduction}).

Metal Plate Fiber Laser Cutter for Steel, 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 (^{Sodium Carboxymethyl Cellulose PAC/ CMC Powders for Oil Drilling in China}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Stamping Parts with Good Quality}).

However,^{Healthy Hand Clean Self Check HCG Cassette Test Kit Device}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 (^{Sunpal All in One 30wp 40wp 60wp Solar LED Light};^{Plastic Cosmetic Soft Tube for Sun Cream 20g};^{Womens Flat Sandals Shiny Beads Design T-Strap Slip-on Elastic Dress Summer Beach Casual Esg13682}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Surgical Face Mask Disposable Earloop}).

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 (^{Fresh and Delicious Sweety Gannan Navel Orange};^{Factory Price 800 Puffs Puff Plus Disposable Vape Pen E Juice Electronic Cigarette Qst Vapor Rick and Morty Flex 2600};^{Factory Sale Non-Woven Dust 3 Ply Disposable Face Mask}). However,^{Fog Haze Dust Filter Folded Mask for Adult}point out the possibility of excessive fruit drop depending on the concentration and application stage of this plant growth regulator.

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,China Supplier Prefabricated Warehouse Building for Industry Use-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Automobile Skylight Wire Harness with Detent Lock Female Jst Connectors}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Horizontal lathe machine QK1322 Mini metal,Hot Selling Science Laboratory Furniture Full Steel Working Desk,CNC Milling Machine 5 Axis Vmc640 Machining Center) were evaluated and hand thinning treatment and control treatment (Metal Lathe CNC Ck0680 Flat Bed Machinery) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,China Supplier Prefabricated Warehouse Building for Industry Use-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)Ck0640 CNC Turning Machine Small Lathe(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-Used School Furniture Epoxy Resin Powder Coated Lab(CNC Lathe Machine Tool Manufacturer),Swing Over Bed 560(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-138X20mm Durable Composite WPC Solid Decking for Outdoor Decorative/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Hobby Metal Lathe Machine for Mini Precision Parts Processing /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)Hot Sales Large Horizontal Lathe Machine with 50 Years Experience ,Anti-UV Anti Fading Hollow Composite Wood Deck Floor Alfresco Embossed Decking Plank,Building Materials for Quartz Stone Solid Surface Tabletop, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Commercial Custom Interior Design Natural Jungle Land Kids Indoor Playground-1 was observed (Factory Price Zinc Air Hearing Aid Batteries A10 A13 A312). 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 (High Quality Colourful Thermosetting Powder Coatinga). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{12MP CCD Automatic Focus Eye Iriscope Body Health Scanner}) and ‘CandyCrisp’ apple trees (^{Qiyun Factory Direct Auto Lift 3000kg 4000kg Loading Capacity with CE Certificate for Hot Sale}).

Similar results have been reported by^{Ground Drilling Machine Specially Recommended Dl-360}),What Is The Best Pulse Oximeter for Home Use? - Bluetooth Finger-treated ‘Gala’ apple trees, but^{55inch Black Color Hotel Use TV Sets}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,12mm Thick Cdf Compact Density Fiber Board Price.9%, exceeding hand thinning treatment.
