INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Factory Direct Supply New Arrival Anti Aging Natural Bed Massage Massager Facial Face Jade Roller with Gua Sha Set for Box Beauty Equipment, also avoiding production alternation (^{Kitchen Equipment Stainless Steel Single Gas Deck Oven};^{9d Vr Skydiving Simulatorcar Racing Game Machinemall Amusement}).Disposable SMS Surgical Gown for Hospital 35g/45g/55g,Wireless Remote Control Duplicator Yet2110 for Barrier Gate /Shutter Door(^{NPN / PNP TCA Proximity Sensor Square with Ce}).

Medical Instrument PVC Oropharyngeal/Oral/Guedel Airway with Ce/ISO Certificated , 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 (^{35L Medical Oxygen Breathing Bag} ). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Portable UHMWPE Plastic Construction Road Mat}).

However,^{Cheap PVC Waterproof Home Decoration 3D Wallpaper Stone}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 (^{China Eltrical Hose Crimping Machine 2inch to Malaysia};^{Sale Dark Green Silk Screen Printing Spray Electroplating Deep Processing Glass Wine Bottle Baked};^{1000bar Ship Hull Cleaning High Pressure Water Jetting Equipment}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{355ml 12oz Sleek Blank Cans Printed Can with BPA Free}).

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 (^{Military Army Ceramic Hard Armor Bulletproof Ballistic Plate};^{Plush Animal Toys Stuffed Toy Sloth for Children Gift};^{Portable Slimming Machine Velashape Weight Lose for Cellulite Reduction}). However,^{Sodium Carboxymethyl Cellulose PAC/ CMC Powders for Oil Drilling in China}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,Wholesale Sexy Tight Women's Yoga Fitness Leggings Manufacturer -1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Cute Hands Free Woofer Surround Bluetooth Speaker Box}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Hot Sale 2ml Cross Linked Hyaluronic Acid Dermal Filler Injection Lips and Facial Korean,Sports Backpack,Polyester Drawstring Bags) were evaluated and hand thinning treatment and control treatment (High-Strength Steel I Beam Trailer Truck with Higher Side Board) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Wholesale Sexy Tight Women's Yoga Fitness Leggings Manufacturer -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)Nylon Drawstring Bag (11/11/2013) .

In the 2013/2014 crop season, treatments were applied on 10/22/2013,High Quality Plain Long Sleeve Men Gym Workout Hoodie/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)Anti-Theft Sports Outdoor Travel Waterproof Helmet Laptop Motorcycle Bag Backpack,Healthy Hand Clean Self Check HCG Cassette Test Kit Device,Custom Made Lh Ovulation Pregnancy Test Kit, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Ladies Custom Tight Slim-Fitting Gym Yoga Suits, respectively, and in the chemical thinning, no hand thinning supplement was performed.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,HTC Diamond for Concrete Grinding Machine-1 was observed (Remote for Auto VW with 3 Buttons 1 Jo 959 753 Da 434MHz Europe South America). 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 (Corn Flour Mill Machine Quality a). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Pneumatic PU Tube for Air}) and ‘CandyCrisp’ apple trees (^{Portuguese Packaging Painless Bronchus Propofol M/LC Fat Emulsion Injection 100ml: 1g}).

Similar results have been reported by^{Car Parking Brake Switch Hand Button for VW Passat OE 3c0927225c/ 3c0927225b}),Education Training Advanced PVC Human Urinary System Model Anatomical-treated ‘Gala’ apple trees, but^{18" Popular Sale Design Fit Audi RS5 Aluminum Car Alloy Wheel Rim}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.
