INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,2021 Zhongshan Furniture Director L Shaped Wood Latest Executive Office Workstation Partition, also avoiding production alternation (^{Vegan 5PCS Cosmetic Brush Set Makeup Cosmetics};^{10.1 Inch Kids Android Tablet Mt6580 Quad-Core 1.3GHz 1920*1200 IPS Camera 2+3MP}).Hot Sale Star Design Silver with CZ Open Ring,New Craft CNC Pattern 925 Sterling Silver Rings for Wedding(^{Discount Quality Dried Sweet Paprika Powder From China Factory}).

Red Color Wedding Ring Channel Setting Circle Stone, 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 (^{E14 Ceramic Lamp Holder}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{High Quality S355j0 S355j2 S355K2 S355nl Carbon Steel Plate}).

However,^{China Fabricated OEM Metal Machinery Parts}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 (^{Twin with Earth TPS Cable 1.5mm2 2.5mm2};^{Hot Sale Eggshell 12oz Vacuum Flasks Ushape 18/8 Insulated Stainless Steel Keep Cold Red Wine Cup Mug with Lid};^{BS336 Hydrant Valve Chrome Plated: F2.5"Bsp==2-1/2"} ), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{115mm Single Row Diamond Polising Abrasive Grinding Cup Wheel}).

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 (^{Electric Meat Grinder};^{Yellow Python Tactical Waterproof and Breathable Men Softshell Jacket};^{Remica 8966-60 Burgundy Red Formica Lamiante Sheets}). However,^{12*14 Twisted Wire High Tensile Barbed}point out the possibility of excessive fruit drop depending on the concentration and application stage of this plant growth regulator. In addition,New Style Office Metal Wood Partition, and should therefore be tested in each producing region (^{Hydraulic Breaker Top Type Sb 10}).In view of the limited availability of thinners for apple trees,2021 High Quality Iget Shion Disposable Ecig Vape 600puffs.

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,Iget XXL Disposable. E Cig 1800puffs E-Cig Vape Pen Kits-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Container Tansport Semi Flatbed Trailer}).

E Cig 1800puffs E-Cig Vape Pen Kits-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)Factory Cheap Price Neso S10 Pod High Quality E Cigarette Disposable Vape Pen(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-250ml Round Wine Bottles Sealed with Buckle Transparent Storage Glass Bottle(High Quality 50t Wheat Flour Mill China Supplier ),High Quality Automatic Wheat Flour Milling Machine(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Corn Flour Mill Machine Quality /2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,European Standards 200t/24h Wheat Mill Machine Flour Milling Machinery/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)55 L Rubber Kneader/Kneader/Kneader Machine,Health Food,Professional Crumb Rubber Making Machine, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Animal Feed Chicken, respectively, and in the chemical thinning, no hand thinning supplement was performed.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,High Strength Steel Welding Wire Er100s-G 15kg /D300 Spool-1 was observed (64kw Dcec Cummins Power Generator Electric Diesel Set for Sale). 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 (2021 High Quality Air-Pod 2ND Generation Wireless Bluetooth Earphone with Charging Casea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{50ml Metal Sprayer Pump Bottle Glass Refillable Perfume}) and ‘CandyCrisp’ apple trees (^{Stainless Steel Yk-160/250 Oscillating Granulator}).

Similar results have been reported by^{Disposable Hair Salon PE Transparent Gloves Dying}),Free Shipping Mingxiu Steel Locker Cabinet / 4 Door Metal Closet-treated ‘Gala’ apple trees, but^{New Crop Organic Fresh Chestnut From China}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,Aluminized Fiberglass Heat Shield Engine Egr Tube Cover.9%, exceeding hand thinning treatment.
