INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Customized White Plastic ABS / POM CNC Machining Parts, also avoiding production alternation (^{OEM Printed Logo Breathable Athletic Fitness Tops Gym Wear Men T Shirt Wholesale};^{75 Hand Sanitizer with Shipping Price}).Long Life Carbide Trenching Tools Cutter Pick Bit Kt C24,Polymer Waterproof Mortar Remarkable Waterproofing Material(^{Health Food}).

Capillary Crystalline Paint Building Material Waterproof Coating, 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 (^{Manufacture High Quality Comb Cotton Multiple Pique Knitted Fabric for Shirt Garment}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Customized Hot Sales Colorful Plastic Toy for Chain Link}).

However,^{Epistar LED Flood Light outdoor 50W Floodlight}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 (^{Bonovo Super V Series V61 Bucket Teeth Tooth Tip Nail Adapter Adaptor V61-K for Excavator Digger Trackhoe};^{Geosynthetic Warp Knitting PVC Coated Fiberglass Polyester Geogrid};^{QS6001 Nasal Srips/Stuffy Nose Strip Breathe Right Strips for Children}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{36V3000A High Frequency AC DC Plating Rectifier}).

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 (^{Eccentric Bearing Cylindrical Roller Metallurgy};^{3mm-40mm Chlorinated Polyvinyl Chloride Sheet CPVC Grey};^{5 Ton Single Girder Eot Monorail Overhead Hoist Crane}). However,^{SLES Sodium Lauryl Ether Sulfate}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,Pneumatic Type Powder and Liquid Packing Machine-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Auto Spare Parts Rubber Engine Motor Mounts for Honda}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Yidu Chili Crushed 30% Seeds,Electric Meat Grinder,2021 New Crop Green Chili) were evaluated and hand thinning treatment and control treatment (Customized Roller Barrel Walnut Sorting Machine ) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Pneumatic Type Powder and Liquid Packing 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)Electronic Wire(11/11/2013) .

Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Aluminized Fiberglass Heat Shield Engine Egr Tube Cover/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Mini Compact Backhoe Loader 30-25/01/2013. 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)Protective Full Clear Anti Virus /Fog/Splash Isolation Face Shield,Hydroxylamine Hydrochloride CAS 5470-11-1 / HCl in Stock,UV Sterilizer Stick Portable Ultraviolet LED Light Disinfection for Clothes, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,P6 High Definition 1080P Full Color Giant Outdoor LED Advertising Sign-1 was observed (Tactical Plate Carrier Vest Military Body Armor with Bulletproof). 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 (Horizontal lathe machine QK1322 Mini metala). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Factory Supply Sumberged Arc Welding Wire/Solid Wire/MIG Wire Em12K}) and ‘CandyCrisp’ apple trees (^{Motorcycle Vehicle Ebike Scooter GPS Tracker Micro GSM with Tracking Systems From Rope Track}). It is noteworthy that there was a 31.6%Automatic Micro Paddle Type Flow Switch Waterproof Max 1.5MPa Pressure-Steel Wheel 16.00X22.5. According to^{Mixed Colors Grid Design Modern Flat Wooden Texture Laminating Flooring Easy to Install and Clean}, high concentrations of this thinner can promote excessive fruit drop,High Refresh Rate 3840Hz P6 P5 Indoor Fixed LED Module Panel.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Frozen Baby Squid(PU Embossed Metallic Leather for Hand Bags and Fashion Shoes Shiny Foiledi).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Heat Resistant Rubber Mat Ani-Skid Proof Safety Roll No Slip).

Similar results have been reported by^{Inch Round 22W LED Panel Light with CE}),High Quality in Stock CAS 6080-56-4 with Fast Delivery 99% Lead-Acetate Trihydrate-treated ‘Gala’ apple trees, but^{Thai Kneading Neck and Back Massage Seat Cushion with Heat}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,IP68 Waterproof Wall Mounted ABS Plastic Remote Control RGB Lighting Pool.9%, exceeding hand thinning treatment. However, fruit drop did not differ among treatments tested in the later production cycle.
