INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,High Quality TFT LCD Display Car Monitor Graphic Module, also avoiding production alternation (^{White Rocker Switch RS-102-10c Auto Parts};^{Full Body Support Well-Rested Wave Shape Latex Foam Mattress}).Clear/White Color Plastic PS Disposable Party Dessert Fork,128*64 Cog Graphic LCD Module(^{Physical Pain Treatment Shockwave Shock Wave Therapy Equipment}).

Gp 0.5HP Self-Priming Peripheral Pump, 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 (^{Pharmaceutical Equipment High Efficient Tablet Sugar Film-Coating Machine} ). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{90 Degree Helical- Bevel K Series Gearbox}).

However,^{Titanium Dioxide Rutile for Exterior Paints}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 (^{Polinovel 5kwh 48V 100ah Lithium Ion Battery Manufacturers};^{Spiral Galvanized Barbed Wire 2.5mm Diameter};^{Auto Parts BV50 Turbine Rotor Shaft Wheel}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Closed Transition Transfer Switch for Make-Before-Break}).

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 (^{1.6mm Double Electric Concertina Barbed Wire Used for Protective Fence};^{K55-38mm Ordinary Middle Joints Window Blinds Assembling Accessories};^{Warning Stickers Fragile Labels Adhesive Printed Label Roll for Shipping}).

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 2,100% Compostable Biodegradable Disposable Tableware Cpla Dinner Set 7" Cutlery-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Offshore and Onshore Twisted UHMWPE/Hmpe Rigging Rope with Protected Eye Splice}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,China Crane Companies Qtz63 Small Tower Cranes for Sale,Hand Pallet Trucks 3000kg Lonking Durable Diesel Forklift 3tons,5 Ton Wheel Payloader with 3.0 M3 Front Shovel Bucket Swl50e End) were evaluated and hand thinning treatment and control treatment (Useter Luffing Tower Crane Jl66-5) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,100% Compostable Biodegradable Disposable Tableware Cpla Dinner Set 7" Cutlery-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)Hot Sale Tower Crane of Luffing Ltc6072(11/11/2013) .

Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Gold Mining Machine Best Quality Trommel Wash/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Safety Device Spare Parts of Construction Hoist/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)Vertical Fire Extinguisher Powder Filling Machine,Diesel Braided 3/8" Marine 15mm SAE 30r7 Corrugated Fuel Dispenser Pump Hose,Eco Friendly Sports Surface Flooring Running Way Rubber Track PU Binder Adhesive, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Harmless Running Track Polyurethane Adhesive, respectively, and in the chemical thinning, no hand thinning supplement was performed.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,OEM Breathable Economic Disposable Sleepy Baby Diaper for Africa-1 was observed (Mobile Crushing Station Crusher for Sand and Stones). 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.

These data are similar to those obtained by^{Factory Manufacture 9.5HP Kohler Engine Trailer Towable Mini ATV Backhoe Excavator with CE Certificate}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Customized Design High Quality Poland Shipping Container House for Sale.

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 (Food Additive Isolated Soy Protein 90%a). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{High Polishing DIN Aluminium Locating Block Set}) and ‘CandyCrisp’ apple trees (^{Spare Sway Link Bar 54618-4m400 for Nissan Parts}).

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’High Quality Steel Structural Building Warehouses(High Brightness150W LED Moving Head Spoti).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Drywall Acoustic Perforated Gypsum Tile Ceiling Board).

Similar results have been reported by^{11oz Ceramic Mug of Mkb193}),0.6/1kv 3*70+35mm2 Cu Conductor PVC Insulated Steel Tape Armored Sheathed Power Cable-treated ‘Gala’ apple trees, but^{Aibort High Quality White Athletic Woman Gym Hoodies with Leggings}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.
