INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Korean car Parts, also avoiding production alternation (^{Tri-Proof Special Street Light};^{Automatic Industrial Gas Steam Electric Heating Big Cooking Pot with Mixer Equipment Jacketed Kettle for Sale}).for iPhone 7 Wireless Bluetooth Earphone with Charger Case 2021,for iPhone5 Apple Earpods with Remote and Mic(^{Best Price 50b24L Ns60L 12V 45ah Mf Korean Car Battery}).

Commercial Air Handling Unit Ahu with Factory Price, 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 (^{500V 1000V 20kv 50kv Silicone Cable Wire}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Standard Roll Hemp Toilet Paper Tissue for Bathroom Commode}).

However,^{Hot Melt Glue Construction for Baby Diaper Sanitary Napkins}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 (^{26*17" 21SPD Electric Moutain Bike};^{Best Performance Hydraulic Press Brake Sheet Metal Plate with E21 System};^{High Quality Graphite Petroleum Coke}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{[0.5m Wide ] Kingtop Carbon Fiber Printable Hydro Dipping Hydrographics Water Transfer Printing Film Wdf833-1}).

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 (^{Customized Design Canopy Promotion Gift Umbrellas Wine Bottle Outdoor Rain Folding Umbrella};^{Factory Directly Wholesale Double Batteries 100km Long Trip Fat Tires Electric Bike B&B 100};^{Movable Church Auditorium P2.6 LED Display Front Open Indoor Rental Screen}).

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,Factory Directly Sale Stainless Steel Steam Jacket Kettle-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Fiber Patch Cord MPO-MPO for High Density Transmission}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Bakery Rotary Rack Ovens for Sale Diesel-Electric-Gas Baking Oven/Nigeria Equipment /Stainless Steel Oven with Trolly and Steam,High Efficiency Portable Home Power Generators 275W 325W 355W 400W,Wholesale 350W /500W/750W 29er Electric Bicycle Bicicleta Mountain Bike) were evaluated and hand thinning treatment and control treatment (Disco Lights Stage 380W Moving Head Beam Spot Light) were compared.

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)Stretch Film of Nylon for Plastic Packing,Energy Storage System 5kw 9.6kwh Battery for Wind or Solar,CNC Hydraulic Sheet Metal Bending Press Brake with Tooling, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)WC67Y /K series sheet metal plate CNC hydraulic press brake, respectively, and in the chemical thinning, no hand thinning supplement was performed.

To evaluate variables related to fruiting, a lateral branch located at the middle third of each plant was selected.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Prefabricated House for Labour Camp Dormitory-1 was observed (Foodstuff Scilating Granulator & Pulverizer ). 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 (Factory Produce High Quality 85 Series Punch Diea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{DA-6 Diethylaminoethyl Hexanoate 98 % TC}) and ‘CandyCrisp’ apple trees (^{HEPA Filter Factory}). It is noteworthy that there was a 31.6%Small Lab Mineral Grinding Pulverizer Micron Powder Planetary Ball Mill-Mining Mill Machine Ball Rod Grinding.

Similar results have been reported by^{RGBW 10W 1LED PAR 16 New LED Can Light}),HDPE 100ml Spray Bottle Plastic-treated ‘Gala’ apple trees, but^{Professional Kinlly Makeup Brush-10PC}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.
