INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Handmade Custom Shape Felt Handbag, also avoiding production alternation (^{Cocoa Protein Powder Packing Machine};^{UL&SAA&TUV 150cm 24W SMD3014 Transparent/Milky Cover T8 Tubes Light}).Virgin Brazilian Human Hair Straight Red Burgundy Women 10-26 Inch,Professional Services From China to Canada Cargo Shipping Rate Air Freight(^{High Quality Coffee and Tea Tumbler}).

China Fashion Sports Shoulder Handle Travel Backpack Bag, 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 (^{Trendy Reusable Shopping Bags}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{2021 Daly Best Chooses Filling Gas Capacity 7L Cylinders Propane Welding Bottle 3kg Withi Factory}).

However,^{Excellent Quality Bzd Type 1500kg Jib Crane with Widely Applied}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 (^{Cable Trunking Tray Suit for 45type Sockets};^{Dextra Aci-318 Standard Mechanical Splice Coupler};^{China Manufacturer Sintered Silicon Carbide Ceramic Ssic Shaft Sleeve for Magnetic Drive Pump}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{OE Standard Auto Brake Parts Truck Automatic Slack Adjuster for Benz 80009/80008}).

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 (^{Fiber Optic Cable Connecter St Sx 3.0mm for Telecom Network};^{Pressureless-Sintered Silicon Carbide Ceramics Ssic Bushing/Shaft Sleeve};^{Food Trailer/Cart with Good Design and High Quality for Sale}).

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,Hi -Vis Class 3 Waterproof 3-in-1 Thermal Bomber Jacket Uniform Parka-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Frozen Mandarin Orange with High Quality}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Prevent Wound Infection After Vaccination/I.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Hi -Vis Class 3 Waterproof 3-in-1 Thermal Bomber Jacket Uniform Parka-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)2oz Plastic Disposable Shot Glass(11/11/2013) .

Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Dissolved Air Flotation Equipment Daf Machine for Wastewater Treatment/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,500ml 75% Alcohol Disinfectant Antibacterial Liquid Disposable Hand Sanitizer Gel/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)Wholesale High Quality 250ml Tin Nice Beverage Drinking Can,15 New Jbl Powerful HiFi Home Theater Wireless Bluetooth PA Professional Karaoke Party Trolley Loud Audio Battery Speaker,15kHz Long Distance Ultrasonic Transducer for 50m, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Fully Stocked LC Single Mode Quad Plastic Fiber Optic Adapter, respectively, and in the chemical thinning, no hand thinning supplement was performed.

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 (^{Six Ways German Type Socket with Light Switch}).

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Foundation Project Air DTH Rotary Micropiles Drilling Rig-1 was observed (Sunmed Bandage Products - Stockinette Bandage). 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.

There was no difference among treatments for fruit weight per plant.

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 (Panel Fixed Socket Compatible with Binder M16 Circular Connector 8pinsa). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{High Pressure Hydraulic Rubber Hose}) and ‘CandyCrisp’ apple trees (^{Concrete Form Snap Ties}). It is noteworthy that there was a 31.6%Seat Cover/Trunk Liner - Absorbent Water Oil Mat-Waterproof PVC Plaid Fleece Picnic Mat Blanket.

Similar results have been reported by^{Inflatable Santas Grotto Bouncer Christmas Bounce House}),Fastener Factory Price M3/ M4 /M6/M8/M12 Hex Socket Button Head Machine Screw for DIN7380-treated ‘Gala’ apple trees, but^{2014/2021/2024/ 2A12 /2224 T651 High Hardness Aluminum Alloy Bar Round}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,Fashion Jewelry 925 Sterling Silver or Brass Diamond Pendant for Sale.9%, exceeding hand thinning treatment.
