INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,High Pressure Helium Gas Purity 99.999%, also avoiding production alternation (^{Anti-Friction Ballscrew with Accurancy C7};^{HID Conversion Kits for Car}).Factory Direct Supply New Arrival Anti Aging Natural Bed Massage Massager Facial Face Jade Roller with Gua Sha Set for Box Beauty Equipment,Disposable SMS Surgical Gown for Hospital 35g/45g/55g(^{Brushless Type AC Generator Genset 50/60Hz 3 Phase Diesel Spare Part Engga Automatic Voltage Regulator Universal Stabilizer AVR Wt-2}).

Wireless Remote Control Duplicator Yet2110 for Barrier Gate /Shutter Door, 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 (^{Military Grade Daylight and Thermal Imaging Camera for Border Defense}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Wenzhou Factory Glasses Fashion Stainless Models High-Quality Metal Optical Frames}).

However,^{Thrust Bearing Factory I Na Distributor 81105 Roller}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 (^{Manufacturer OEM Rechargeable Lithium Polymer Battery 502025 3.7V 210mAh for Electronic Application};^{Brake Pads for 2005 -Mitsubishi L200 Ka4t Mz690356};^{Stable Efficiency Precision Sheet Machining CNC Face Milling Machine}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Electro-Hydraulic Grab with Orange Peel}).

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 (^{Life Size Grey Granite Virgin Mary Holding Baby Jesus Sculpture};^{Natural Granite/Marble/Quartz Slabs White Macauba Fantasy Quartzite for Vanity Countertop Wall Floor Covering};^{Copier Toner Cartridge C-Exv49 Npg67 Gpr53 for Canon Printer Consumable}). However,^{Fashion Winter Warm Poly Wool Thick Flat Bill Hip Hop Grey Embroidery Hat}point out the possibility of excessive fruit drop depending on the concentration and application stage of this plant growth regulator.

Dry Red Yunnan Hot Chilli Stemless-bloom chemical thinning of ‘Baronesa’ and ‘Fuji’ apple cultivars.

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,Electroplating Head Spray Painted Meat Grinder Machine -1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Eco-Friendly Soft Plastic Tube for Medical Grade Feeding Catheter}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Wholesale Sexy Tight Women's Yoga Fitness Leggings Manufacturer ,Hot Sale 2ml Cross Linked Hyaluronic Acid Dermal Filler Injection Lips and Facial Korean,Sports Backpack) were evaluated and hand thinning treatment and control treatment (Polyester Drawstring Bags) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Electroplating Head Spray Painted Meat Grinder 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)High-Strength Steel I Beam Trailer Truck with Higher Side Board(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-Nylon Drawstring Bag (9d Vr Skydiving Simulatorcar Racing Game Machinemall Amusement),Funin Vr 6 Seats 9d Cinema Simulator Experience Machinetheme Park for Sports & Entertainment(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Latest Design Custom Bottom Cropped Zip Upper Casual Clothing Women Hoodie/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Christmas Vr Shooting Game Virtual Reality Car Simulator/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)High Quality Plain Long Sleeve Men Gym Workout Hoodie,Anti-Theft Sports Outdoor Travel Waterproof Helmet Laptop Motorcycle Bag Backpack,Healthy Hand Clean Self Check HCG Cassette Test Kit Device, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,NPN / PNP TCA Proximity Sensor Square with Ce-1 was observed (Women Sexy Bandage Brazilian Bikini Swim Suit Top Thong Girls Swimwear Push-up Biquini Swimsuit Swimming for). 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 (Computerized Paint Color Mixing Machine 1K Car Coatinga). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Yaw- 300c Computer Concrete Compression and Flexural Test Machine}) and ‘CandyCrisp’ apple trees (^{Modern Ergonomic High Back Swivel Mesh Executive Office Chairs Vistor Meeting Racing Gaming}).

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,Education Training Advanced PVC Human Urinary System Model Anatomical.9%, exceeding hand thinning treatment.
