INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Custom printing 13.56MHz encoding PVC MIFARE Classic EV1 1K RFID business Cards, also avoiding production alternation (^{Biodegradable and Compostable Custom Logo Printed Courier Mailing Bags};^{New Arrival Multi-Layer Prefabricated Light Steel Structure Dormitory}).OEM High Precision Aluminum Medical Machinery Die Casting Parts,6.50r16 Hot Sells Truck Bus Tubless Car Tyre TBR(^{PCB and PCBA Manufacturer for Tablet PC Smart Phone}).

Tile Grout Additives Industrial Chemicals HPMC, 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 (^{Z4612 Paper Coffee Cup Carriers - to Go Rectangle 2-Cup}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{ERW Steel Pipe Mill for Carbon and Gi}).

However,^{PP Geotextile Fabric for Highway}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 (^{Electro-Static Powder Spraying Metal Halide Floodlight} ;^{2-3t/H Output Biomass Fuel Wood Sawdust Rice Husk Pelletizer};^{Selling 3 Ton Workshop Wall Mounted Jib Crane Manufacturing}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Hons New Design High Quality Accuracy Four Chutes Multi-Functional Classical CCD Rice Color Sorter Machine for Grain &}).

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 (^{Coin Type Supercapacitor -40c- 70c} ;^{Us Type Drop Forged Chain Turnbuckle with Eye &};^{5W UV Laser Machine for Plastic Marking}).

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,Polymer Concrate Water Drain Channel System for Factory-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Cost Effective Rubber Crumb System to Recycle Waste/Scrap/Used Tires/Tyre}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Telegraph Pole Mounting Bracket,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) were evaluated and hand thinning treatment and control treatment (High Quality Small Plastic Injection Machine) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Polymer Concrate Water Drain Channel System for Factory-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)China 20/40FT Prefabricated Modular Steel Structure Prefab Mobile Shipping Container House(11/11/2013) .

In the 2013/2014 crop season, treatments were applied on 10/22/2013,Sex Toy-Water-Based Lubricant Oils /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,Natural Lapis Lazuli Carved Bird /Raven Skull Pendant Carving #9j36-1 was observed (High Quality PVC/ UPVC Door Factory Price). 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 (White Granule Refined Sodium Chloride Salt for Coating Solidificationa). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Blasting Drilling Rig 115mm for Borehole}) and ‘CandyCrisp’ apple trees (^{Wholesale Chinese Semi Trailer Truck Tire 295/75r22.5 11r22.5 285/75r24.5 11r24.5 China Tyre Price for Sale}). It is noteworthy that there was a 31.6%Selling 3 Ton Workshop Wall Mounted Jib Crane Manufacturing-Ske Brand Tubular Pipe Belt Conveyor for Cement Plant Fuel Material Handling. According to^{High Temperature PPR Union Coupling Socket}, high concentrations of this thinner can promote excessive fruit drop,Mining Belt Conveyor with Large Capacity in Material Handling Industry.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Heavy Duty Pallet Racking for Industrial Warehouse Storage Solutions(75 Hand Sanitizer with Shipping Pricei).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Health Food).

Similar results have been reported by^{Manufacture High Quality Comb Cotton Multiple Pique Knitted Fabric for Shirt Garment}),High Peaked Marquee Tent Event for Real Estate -treated ‘Gala’ apple trees, but^{Shinho X-700 Fiber Fusion Splicer for FTTX/FTTH Splicing Installation and Maitaining}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.
