INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,OEM High Precision Aluminum Medical Machinery Die Casting Parts, also avoiding production alternation (^{Water Chilled Fan Coil Units for Duct Installation} ;^{20L Suction Filter Lab Rotary Vacuum with Pump}).6.50r16 Hot Sells Truck Bus Tubless Car Tyre TBR,Tile Grout Additives Industrial Chemicals HPMC(^{Brass Straight Union in 3 Pieces Fxm} ).

2t Per Hour Household Water Filter System, 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 (^{6.5HP Gasoline Motor Agricultural Irrigation Water Pump Price List} ). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{300puffs Electronic Disposable for Puff Bar E Cigarette Wholesale 1.3ml Single Vape Pen}).

However,^{Lab / Mini Portable Powder Coating Machine with Gun}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 (^{Chemical Lace for Clothing/Garment/Shoes/Bag/Case} ;^{2.1MP 20X Waterproof Wiper Night Vision IR Laser Rugged Patrol Car Roof PTZ Camera};^{IP68 Waterproof Wall Mounted ABS Plastic Remote Control RGB Lighting Pool}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Omni CNC Machine 2060 with Auto Tool Changer SGS}).

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 (^{Cold Rolled Mr Tin Plate Coils SPCC ETP Tinplate Coil};^{PP Strap/Band Single Shaft Plastic Shredder Crusher};^{New Crop Frozen Seaweed Wakame Stem Cut}).

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,Telegraph Pole Mounting Bracket-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Rose Jam /Rose Gulkand/ with Sugar / Petal Honey}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Waterproof 65 Inch Outdoor 2500nit LCD Kiosk Advertising Digital Touch Totem Windows Display Screen,Hot Sale 4 Inch Sintered Double Row Segment Diamond Grinding Wheels for Concrete,High Quality Small Plastic Injection Machine) were evaluated and hand thinning treatment and control treatment (China 20/40FT Prefabricated Modular Steel Structure Prefab Mobile Shipping Container House) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Telegraph Pole Mounting Bracket-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)Prime Mover 10 Wheeler 6X4 Sinotruk HOWO Tractor Head Truck(11/11/2013) .

In the 2013/2014 crop season, treatments were applied on 10/22/2013,Fingerprint Digital Residential Apartment Door Lock for Building Projects/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.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,SMS Doctor's Gown Isolement Blouse Chirurgicale Disposable Patient Doctor Sterile-1 was observed (China Factory Supply Disposable SMS Nonwoven Fabrics Patient Surgical Gown with High Quality for Hospital Use). 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 (Galvanized Steel Zinc Coating Sheet/Galvanised Coil / Good Package /Galvanized Platea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Used Original Komatsu PC220 18m Long Boom Excavator}) and ‘CandyCrisp’ apple trees (^{6061/6082/7075 T4/T5/T6/T651/T6511 Precise Extrusion Aluminum Alloy Round Pipe}).

According to^{Round 2.2kw Er20 Water Cooled Spindle for CNC Engraving Router}, high concentrations of this thinner can promote excessive fruit drop,Tower Crane 6ton Jib Length 50m.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’High Peaked Marquee Tent Event for Real Estate (Pop up Modular Designed Flor Socketsi).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (18.5'' Capacitive Touch Screen Monitor 10 Points Shenzhen Factory Cheap USB HMI LCD Pcap).

Similar results have been reported by^{0-10V Dimmable 8inch 30W Ceiling Downlight with White Housing}),High Quality TFT LCD Display Car Monitor Graphic Module-treated ‘Gala’ apple trees, but^{Women Functional Pocket High Waist Casual}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,Clear/White Color Plastic PS Disposable Party Dessert Fork.9%, exceeding hand thinning treatment. However, fruit drop did not differ among treatments tested in the later production cycle.
