INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,PRO 36W Nail LED Lamp for UV Light Gel Polish, also avoiding production alternation (^{Dlc Industrial High Power LED Bay Luminaire Light 60~320W with ETL Ce};^{Natural White Cow Split Leather Welding Welder Safety Work Glove}).925 Sterling Silver Charm Heart Pendant Jewellry,Car Floor Mat/Car Carpet/Foot Mat for Honda Cars with 360d Full Coverage(^{Home Appliance Air Purifier HEPA+UV+Anion+Carbon 5 Layers}).

Yaw- 300c Computer Concrete Compression and Flexural Test Machine, 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 (^{3.5 Inch LCD Driver IC Hx8238d 54pin Touch Screen}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Hcns HDPE Geocell for Road Construction}).

However,^{Helical Bevel Geared Motor with Output Solid Shaft}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 (^{Factory Wholesale Disposable Protective 3 Ply Mask Price};^{Dingli 18m Jcpt1823rt Engine Scissor Lifts};^{6m Diameter Igloo Large Geodesic Dome Tent for Outdoor Activities}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{8 Ton Horizontal Steam Automatic Feeding Coal Boiler}).

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 (^{Anti-Slip HDPE Construction Rubber Road Mat with High Loading and Durable Flooring Tiles};^{Car Accessory Front Grill for Ford F150 F250};^{High Quality Invisible Condom for Man}). However,^{Automotive Parts}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,WUZHENG Heavy Load Cargo Diesel Dump Three Wheel Motorcycle-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{High Quality 75*80 Pre-Printing Thermal Paper}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Semiautomatic Dw38nc Hydraulic Tube Bender,Hnx Through Type Waterproof Ex Cable Gland M48,Polyacrylamide-Based Flocculants for Solid/Liquid Separation) were evaluated and hand thinning treatment and control treatment (CNC Adjustable Motorcycle Hand Clutch Brake Levers for Ktm Duke 200 390) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,WUZHENG Heavy Load Cargo Diesel Dump Three Wheel Motorcycle-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)Disinfectant 3kg Oxygen Bleaching(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-New Acrylic Two-Color Transparent 7PCS Set for Various Games Dice N&R(Hongrun HYT-500 Medical Silent Dental Oilless Air Compressor),Hot Sale Gas Lava Rock Grill (control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Hair Factory Direct Human Lace System/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Xb2-Bd21 Standard Handle Selector Push Button Switch/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,Heat Resistant Rubber Mat Ani-Skid Proof Safety Roll No Slip-1 was observed (850lm/M SMD2835 LED Neon Light). 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^{Power Tiller Mini Tracotr Farm Agriclutural Machinery Tractor}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Computer Control Non Woven Vest Bag Machine Zxl-A700.

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 (High Production Speed Pembekal Non Woven Bag Making Machinea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Checkweigher for Seafood}) and ‘CandyCrisp’ apple trees (^{200W Solar Monitoring Remote Control system}). It is noteworthy that there was a 31.6%High Production Speed Pembekal Non Woven Bag Making Machine-6" 100V 6W Metal Ceiling Loudspeaker. According to^{Electric Go Cart Zc-Gk-88e} , high concentrations of this thinner can promote excessive fruit drop,1100kg IQF Tunnel Freezer for Fruits/Vegetables/Meat/Fish/Shrimp/Pasta/Poultry with Certificate.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Polyresin/Resin Craft Festival Gift Christmas House with LED Light(Stainless Steel Tube i).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Diesel and Gasoline Analysis Lab Equipment ASTM D86 Distillation Apparatus).

Similar results have been reported by^{UL62 St Flexible Cord Cable PVC Insulated Outdoor AC Power Extension}),Customized Basketball Figurine with High Details-treated ‘Gala’ apple trees, but^{KN95 Protect Mask Disposable Face with Certificate}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,Medical Equipent Air Compression Leg Massager Lymphatic Drainage.9%, exceeding hand thinning treatment.
