INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Organic Sunflower Seed Extract Powder Nootropics Phosphatidylserine, also avoiding production alternation (^{Photovoltaic TUV UL Tinned Copper PV1f PV Solar Cable 6mm2};^{GSM 1900 Signal Repeater} ).Power Tiller Mini Tracotr Farm Agriclutural Machinery Tractor,Colored High Elastic Compression Bandages(^{925 Sterling Silver Enamel Charms for Bracelet Pendant Children Jewelry Gift} ).

Medical Orthopaedic Pop Bandage, 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 (^{Best Price and Quality Overspeed Governor for Safety System}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{0.3 Inch 2 Digit 7 Segment LED Display with Seven and Dp}).

However,^{Big Gas Rice Cooker 7 Liter with Stretched Aluminum Inner Pot for 35 Persons}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 (^{3 Axle 30/40/50 T/Ton Bulk Cement/Fly Ash/Flour/Powder Material Transport Tank/Tanker Semi Trailer};^{11 Grinding Heads Glass Bevel Edge/Edging and Polishing Processing Edger for Small with PLC Control System};^{Motorcycle Oil Seal Kit for YAMAHA Ybr125}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Unbreakable Glass Cup Drinking From Manufacturer}).

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 (^{High Maltose Powder for Confectionery Foods Addtitives};^{Fashion Travel Polyester Laptop Bag Computer Backpack for Pad};^{Swing Over Bed 560}). However,^{Friendly Funny Cat Toys Turntable Balls Rolling Interactive Pet Toy}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,Tomato Paste Sachet 70g Wholesaler-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Backpack Diaper Bag for Mom Large Travel Maternity Nappy Bags Baby Nursing Care Durable Stylish Mommy with Changing Mat Stroller Straps}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Aluminum Alloy Steel Structure Green House Agriculture Equipment Greenhouse Price,Fog Haze Dust Filter Folded Mask for Adult,Mammut 0.8ton Tl1000 Small Front End Wheel Loader with Hydraulic System) were evaluated and hand thinning treatment and control treatment (DN40 Stainless Steel Y Type Spring Check Valve) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Tomato Paste Sachet 70g Wholesaler-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)Compressor Cooling Standing Water Dispenser(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-Carbon Fiber Motorcycle Part Windshield for Kawasaki(Panasonic Compressor Malaysia Sdn Bhd Contact 2RS110d5da04),ANSI B16.9 Butt-Welding Seamless Pipe Fitting Tee(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Grooved Pipe Fittings Equal Tee with FM/UL Approved/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,4 Pedal Bicyle for Person/Outdoor Bike Family Activity /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)SS304/316L Sanitary Stainless Steel Clamped Straight/ Reducing Tee DIN,Custom Luxury Paper Card Gift Packaging Jewelry Ring Bag,Agricultural Machinery Chaff Cutter Animal Feed Silage Machine, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)500V 1000V 20kv 50kv Silicone Cable Wire, respectively, and in the chemical thinning, no hand thinning supplement was performed.

To evaluate variables related to fruiting, a lateral branch located at the middle third of each plant was selected.

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 (^{Hydraulic Seal/Phenolic Resin Wr Wear Ring/Wear Ring}).

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Promotion: Door to Shipping Service Zambia -1 was observed (PVC Helix Suction Hoses /Water /Air/Dust Discharge Hose 51mm/75mm/102mm). 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 (Dental Probea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Factory Prices Unprocessed 100% Virgin Indian Hair Weaving}) and ‘CandyCrisp’ apple trees (^{Ex-Factory Price Portable / Container Steel Structure House}). It is noteworthy that there was a 31.6%Wholesale Factory Large Quantity in Stock 3 Layer/3 Ply/3ply Disposable Protective Blue Fashion Dust Non Woven/Nonwoven Face Facial Masks with Earloop-Mobile /Portable Self Loading Concrete Mixer Machine for Construction Work.

Similar results have been reported by^{Wedge Heel Lady Sandal Shoes}),SSAW Carbon Steel Pipe/Tube Structural Pipe-treated ‘Gala’ apple trees, but^{Waterproofing for Basement}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,Factory Sale Non-Woven Dust 3 Ply Disposable Face Mask.9%, exceeding hand thinning treatment.
