INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,4W LED Panel Down Light 110mm Round Shape, also avoiding production alternation (^{High Strength Steel Welding Wire Er100s-G 15kg /D300 Spool};^{Tendrillar Page}).High Quality Wholesale Price Ultra Thin LED Panel/Ceiling Light,LED Solar Landscape Lamps All-in-One/Integrated Street Garden Wall Light(^{Custom Luxury Paper Card Gift Packaging Jewelry Ring Bag}).

Sc 8 Port Fiber Optic Terminal Box, 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 (^{Electric Hydraulic Grab Bucket for Scrap}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Car Parts Cylinder Head for Renault Megani K7m K7j/R19 7701468858  7701472681 7701475893e7j/J8s/S9w/M9r/M9t/F9q/R9/R12/K9K/G9t/G9u/M9r/M9t}).

However,^{Kitchen Equipment Stainless Steel Single Gas Deck Oven}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 (^{9d Vr Skydiving Simulatorcar Racing Game Machinemall Amusement};^{NPN / PNP TCA Proximity Sensor Square with Ce};^{35L Medical Oxygen Breathing Bag} ), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Full Foot Snorkeling Free Diving Flippers}).

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 (^{1000bar Ship Hull Cleaning High Pressure Water Jetting Equipment};^{Ricardo Power Generator Set 130kw / 163kVA};^{Roof Ventilation Ridge Ventilator}). However,^{No Splinter Peel Garden WPC Timber Tile Patio Composite Click Decking}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,Oxygen Cutting Torch Welding Regulator Gauges-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Posco Brand 304 Ba Finished Stainless Steel Coil}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,R134A T3 Condition Air Cooled Packaged Rooftop HVAC Unit,High Brightness150W LED Moving Head Spot,High Quality Audio Cable Factory RCA ) were evaluated and hand thinning treatment and control treatment (RF-650 Pet) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Oxygen Cutting Torch Welding Regulator Gauges-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)Africa customer favorite Shacman 6X4 Trailer Head Truck Tractor(11/11/2013) .

Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Damask Uphostery Polyester Curtains and Sofa Cloth 300cm/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Manufacturer SPFS/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 Speed Single and Double Color Injection Model 8K 2.1V 48gbps HDMI Cable,O Neck Long Sleeve Shirts Fitness Thumb Hole Sweatshirt,Portable VCD player, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,SKX2-80A Electric Automatic Transfer Switch-1 was observed (Sunpal All in One 30wp 40wp 60wp Solar LED Light). 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 (Factory Sale Non-Woven Dust 3 Ply Disposable Face Maska). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Fog Haze Dust Filter Folded Mask for Adult}) and ‘CandyCrisp’ apple trees (^{Hot Forged Cold Work Mould Steel Block 1.2080 D3 SKD1 Cr12}).

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Aluminium Alloy Anal Plug with Heart Shape Diamond(Emergency Training Medical Use Trauma Simulation CPR Manikini).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (24V DC Solar 100W LED Street Light with MPPT Controller).

Similar results have been reported by^{Portable Cryolipolysis Cooling Sculpting Weight Loss Beauty Machine}),Plastic Cosmetic Soft Tube for Sun Cream 20g-treated ‘Gala’ apple trees, but^{Mini Travel Soap in Box Paper Hand}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,PA System Three-Way Touring Line Array Speaker.9%, exceeding hand thinning treatment.
