INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Rock Mine Quarry Aggregate Primary Jaw Crusher, also avoiding production alternation (^{General Motorcycle LED Turn Signal Light Flash Direction for YAMAHA Fz16 Honda Kawasaki Z1000sx};^{Permanent Strong Ring Nickel Coating NdFeB Neodymium Magnets}).Z4612 Paper Coffee Cup Carriers - to Go Rectangle 2-Cup,Mobile Crushing Station Crusher for Sand and Stones(^{Bottling Machine with Discount Price/Drink Filling Machinery Manufacturer/Making Bottle Manufacturing Machines/Manufacture of Mineral Water}).

Protective Surgical Medical Face& Mask, 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 (^{Leading Export Super High Power Graphite Electrodes for Eaf Smelting with Nipples}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Cody Lundin Women Seamless Sport Gym Leggings Ladies Running Fitness Yoga Pants}).

However,^{Mobile Temperature Measurement and Disinfection Warehouse}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 (^{Roronoa Zoro One Piece Anime Shusui Katana Sword - O Wazamono Grade Cosplay};^{Nylon Zipper Printing Kll269};^{Boiler and Pressure Vessel Steel Plate P265gh P295gh P335gh Aormor}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{304 Stainless Steel Electric Swing Barrier}).

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 (^{5.99 Inch Mpos NFC 4G Handheld Android POS Terminal};^{Dn150 F4 DIN Pn16 Non Rising Flanged Water Seal Gate Valve};^{Low Price AAMI Level 1 Pet+PA Waterproof Polypropylene Barrier Protection Spunlace Anti Alcohol Disposable Surgical Gown}).

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,High Quality 12/24 Core Fig8 Self-Support Aerial G652D Fiber Armour Optical Cable -1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Korean Style School Shoulder Bag}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Xpon Ont Remotely RF Signal on/off,Rolled Edge Cylinder Glass Lampshade for Chandelier Lamp,Manufacturer Bluetooth 5.0 Headset Direct Sale Tws Wireless) were evaluated and hand thinning treatment and control treatment (Hot Sell in Poland N95 KN95 FFP2 Face Mask Facial Respirator Wholesale Price Dust Facemask) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,High Quality 12/24 Core Fig8 Self-Support Aerial G652D Fiber Armour Optical Cable -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)Disposable Surgical Combined Spinal Epidural Anesthesia Puncture Kit/Disposable Lumbar Mslapk(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-Lunch Bag (High Density and Strength WPC Decking Plastic Clips),China Non Woven Earloop 4 Ply Disposable Kn95 Face Mask(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-CO2 Laser Engraving Cutting Machine for Glass Leather Stone 4040 40W with Ce FDA/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,FTTH 16 Port Pon CATV EDFA with Wdm 2u Rack/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,Organic Moringa Powder Leaf Extract/ Oleifera/Seed Oil-1 was observed (3.5L Large Capacity Home Use Digital Multifunction Without Oil Air Fryer). 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.

There was no difference among treatments for fruit weight per plant.

These data are similar to those obtained by^{Personalized Fisherman Bucket Hat with Face Shield for Men Women Kids Anti Dust Cap Fog}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,4 Pedal Bicyle for Person/Outdoor Bike Family Activity .

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 (Mobile Camper Trailer/ Trailer/Fast Food Kitchen Trailera). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Pet Preform Pco1810}) and ‘CandyCrisp’ apple trees (^{Biodegradable and Compostable Mailer Envelope Bags Corn Starch Customized}). It is noteworthy that there was a 31.6%Custom Luxury Paper Card Gift Packaging Jewelry Ring Bag-Agricultural Machinery Chaff Cutter Animal Feed Silage Machine. According to^{Wood Aluminum Glass Sunroom / Sun Room/ Winter Garden/ Conservatory}, high concentrations of this thinner can promote excessive fruit drop,500V 1000V 20kv 50kv Silicone Cable Wire.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Wholesale Custom Different Sizes Gift Paper Bag for Clothes(0.6t to 6t Mini-Excavatricei).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (PRO 36W Nail LED Lamp for UV Light Gel Polish).

Similar results have been reported by^{Wholesale Bulk OEM Pack Chicken Flavor Animal Feed Dry Dog Food}),Tactical Plate Carrier Vest Military Body Armor with Bulletproof-treated ‘Gala’ apple trees, but^{Virgin LLDPE /HDPE/LDPE Resin/ Pellets/Granules Plastic Raw Materials Recycled Linear Low Density Polyethylene Film Grade}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,Print Logo 5kg Slider Zipper Cat Food Packaging Bags.9%, exceeding hand thinning treatment.
