INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Notification Telephone Number Temporary Parking Card, also avoiding production alternation (^{Standalone RFID Access Control for Single Door and Security};^{Manufacturers 100 Watt LED Street Light 1000 Motion Sensor Solar}).Strong Permanent Sintered Neodymium Ring Magnet,Factory 5.0 Inch 800*480 Digital Full Color LCD Module Panel with Capacitive Touch Screen(^{Fashion Jewelry 925 Sterling Silver or Brass Diamond Pendant for Sale}).

Color Custom Multi-Cylinder Diesel Engine for Pump Generator Set, 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 (^{Ceramic Fiber Insulation Blanket 1400c for Forges}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{3kVA Three-Phase High Accuracy Full-Automatic AC Voltage Regulator}).

However,^{Walkie 1.5t 1500kg Scale Electric Pallet Truck}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 (^{Wholesale Fashionable Jewelry 925 Sterling Silver or Brass Cubic Zirconia Hip Hop Ring};^{Spriral Bevel Gear for Farm};^{Sulfur Black for Cotton Dyes}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Waterproof Small Durable Pagoda Outdoor Event Exhibition Tent}).

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 (^{Automatic New Snack Cream Sandwich Biscuit Machine with Packaging Sandwiching Making};^{Small Drinking Water Beverage Manufacturing Equipment Scale Bottling Machine};^{Luxury Stone Bolivia Blue Granite Slabs for Wall}). However,^{High Quality China Dinner Set Porcelain Tableware Plate Bowl for Daily Use}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,Greenpedel 36V 250W 350W Brushless Geared Ebike Motor for Bicycle-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Newest Leak-Proof Pod System Kit Fruits Flavors Vape Pen E-Cigarette}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,High Quality Forged Steel Grinding Ball with Low Abrasion,Forged Grinding Steel Balls / Mill for Minings,Kunshan Yuncheng Nylon Films) were evaluated and hand thinning treatment and control treatment (Plastic Packaging Materials for Food Bag Making by BOPA Films) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Greenpedel 36V 250W 350W Brushless Geared Ebike Motor for Bicycle-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)LED Solar Street Light 100W 120W 150W with Mono Poly Panel to Africa North America South Southeast Asia Europe(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-CO2 Laser Cutter Machine Metal and Non-Metal Cutting(16r 330W Beam Moving Head Light Stage),Newest Price MID Motor Kit /Tsdz2 36V 350W(control).

In the 2013/2014 crop season, treatments were applied on 10/22/2013,Factory Manufacture High Efficiency Popular 340W /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)Mini Laser Engraving Machine CNC Engraver,330W Beam Spot Moving Head Stage Light,Dlc ETL Cefactory Wholesale Price LED UFO High Bay Fixture Industrial Light IP65 Waterproof , thinners were applied.

Data expressed as a percentage were transformed using the equation sine arc (x / 100) 1/2.

Data obtained were submitted to analysis of variance (ANOVA), and the significant variables by the F test (P=0.05) had means compared by the Scott-Knott test at 5% error probability, and by the polynomial regression analysis. Statistical analyses used the Sisvar software, version 5.3 (^{Tendrillar Page}).

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Home Use Maize and Fertilizer Walker Planter Agricultural Machine-1 was observed (Electric Hydraulic Grab Bucket for Scrap). 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 (Sale Dark Green Silk Screen Printing Spray Electroplating Deep Processing Glass Wine Bottle Bakeda). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{1000bar Ship Hull Cleaning High Pressure Water Jetting Equipment}) and ‘CandyCrisp’ apple trees (^{Men's Down Jacket Short Outdoor Sports Thicker Plus Size Warm}). It is noteworthy that there was a 31.6%11oz Ceramic Mug of Mkb193-Two-Tone Porcelain Bouillon Cup of Syb148. According to^{Roof Ventilation Ridge Ventilator}, high concentrations of this thinner can promote excessive fruit drop,Wholesale Top Quality Flower Scent 1oz 29ml Travel Size Antibacterial Alcohol Waterless Gel Hand Sanitizer.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’High Quality Cold Rolled Stainless Steel Sheet (Womens Flat Sandals Shiny Beads Design T-Strap Slip-on Elastic Dress Summer Beach Casual Esg13682i).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Wre3 Wre5    Wre25  Wre10  Wre26 Tungsten Rhenium Wire Thermocouple).

Similar results have been reported by^{Remote for Auto VW with 3 Buttons 1 Jo 959 753 Da 434MHz Europe South America}),10ml Plastic and Glass Small Travel Perfume Bottle-treated ‘Gala’ apple trees, but^{50t/D Rice Plant Processing Machine Whitener}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.
