INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,18.5" Open Flat Capacitive LCD Touch Screen Monitor, also avoiding production alternation (^{PCB and PCBA Manufacturer for Tablet PC Smart Phone};^{Z4612 Paper Coffee Cup Carriers - to Go Rectangle 2-Cup}).Milk Processing Plant Production Line,Top Quality Food Grade Material 300mAh Battery Vape Pod Cartridge(^{PP Geotextile Fabric for Highway}).

High Quality 5.1 Home Cinema Multimedia Speaker, 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 (^{Electro-Static Powder Spraying Metal Halide Floodlight} ). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Warehouse Storage Double Arm Heavy Duty Cantilever Racking}).

However,^{2-3t/H Output Biomass Fuel Wood Sawdust Rice Husk Pelletizer}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 (^{Selling 3 Ton Workshop Wall Mounted Jib Crane Manufacturing};^{Fantasy Natural Stone Countertops Granite/Quartzite/Marble Calacatta Oro White Rectangle Inner Table Tops for Furniture Cabinets Design};^{Portable Telescopic Pole Inspection Camera System for Roof Checking}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{1045 Steel Chrome Plated Bar}).

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 (^{Factory Price Support 1080P 4K Male to Aoc Dp Cable Mini Displayport};^{Waterless Disinfectant 75 % Ethanol Hand Care Sanitizer};^{Metal Sheet Pipe CNC Laser Cutting Engraving Machine in Agricultural}). However,^{Anti Slip Safety Interlocking Hollow Rubber Floor Mats for Deck/Boat/Outdoor/Kitchen}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 2,5.1 Home Theater -1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Used Machine Cat 312c 320b 336D 330c 320d Excavator for Sale in Low Price}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Glass Cream Jar 20g,High Quality Canvas Men's Messenger Bag Genuine Leather Shoulder,Deck Installation Plastic Fasteners) were evaluated and hand thinning treatment and control treatment (Professional Crystal Microdermabrasion Beauty Machine ) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,5.1 Home Theater -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)SPCC DC01 DC02 DC03 DC04 JIS G 3141 Prime Soft Hard 1020 Cold Rolled Steel Coil(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-Coleus Forskohlii Extract Plectranthus Barbatus(Factory Wholesale Organic Pure Bitter Gourd Melon Seeds Powder Momordica Charantia Extract),Organic Moringa Powder Leaf Extract/ Oleifera/Seed Oil(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-5% Flavones/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Reliable Factory Supply Wheat Grass Powder Bulk Organic Juice/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)Organic Sunflower Seed Extract Powder Nootropics Phosphatidylserine,Power Tiller Mini Tracotr Farm Agriclutural Machinery Tractor,Colored High Elastic Compression Bandages, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Medical Orthopaedic Pop Bandage, respectively, and in the chemical thinning, no hand thinning supplement was performed.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Custom Logo Printed White Eco Gift and Food Kraft Paper Packaging Bags-1 was observed (Xpon Ont Remotely RF Signal on/off). 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 (High Temperature PPR Union Coupling Socketa). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{DIN92-59220 Lead Acid Maintenance Free Mf Automotive Car Battery 12V 92ah}) and ‘CandyCrisp’ apple trees (^{Transparent 89mm Neck Size Mouth 10oz 300ml Plastic Food Jars with Lids}).

Similar results have been reported by^{Bonovo Super V Series V61 Bucket Teeth Tooth Tip Nail Adapter Adaptor V61-K for Excavator Digger Trackhoe}),Ammonium Chloride Fertilizer Pellet Granulator-treated ‘Gala’ apple trees, but^{Mirror Polished Wear Resistant Round Zirconia Ceramic Bar}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.
