INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,5% Flavones, also avoiding production alternation (^{Factory Sale Hospital 24 Hours Working 2L Oxygen Generator Machine Concentrator};^{New Style Office Metal Wood Partition}).Reliable Factory Supply Wheat Grass Powder Bulk Organic Juice,Organic Sunflower Seed Extract Powder Nootropics Phosphatidylserine(^{Factory Direct Straw Grass Handwoven Birdhouse for Outdoor Decor}).

Power Tiller Mini Tracotr Farm Agriclutural Machinery Tractor, 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 (^{LED Overhead Surgical Lights Used in Operating Room}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Compostable Custom Biodegradable Plastic Packaging Mailing Bags with Ok Compost Certification}).

However,^{Semi Automatic Micro Dosing / Powder Filling Machine}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 (^{Mpd Insulated Bullet Male Disconnects};^{Hot Selling Rear Shock Suspension 26'' Aluminum Alloy Frame MTB Mountain Bicycle};^{28mm High Quality Hand Trigger Sprayer with Confortable Wrench}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{China Manufacturer Isuzu 4X2 420PS Tractor Trucks for Sale}).

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 (^{Good Reputation Polyester Green Simply Dog Clothes} ;^{Multi-Functional Facial Oxygen Jet Peel Equipment};^{Named Mk Electric Bike for Adult}). However,^{Wireless Car Charger Mount 15W Qi Fast Charging Auto-Clamping Windshield Dash Air Vent Phone Holder Compatible with iPhone 11/11 PRO/11 PRO Max/Xs/X/Xr}point out the possibility of excessive fruit drop depending on the concentration and application stage of this plant growth regulator.

Carved Metal Panel-bloom chemical thinning of ‘Baronesa’ and ‘Fuji’ apple cultivars.

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,Aluminium Shutters Between Double Hollow Glass Electronic Control for Shading or Partition-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{1HP Woodworking Dust Collector}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,White Color Leno Anti Hail Net for Orchard,Tomato Paste Sachet 70g Wholesaler,Aluminum Alloy Steel Structure Green House Agriculture Equipment Greenhouse Price) were evaluated and hand thinning treatment and control treatment (Fog Haze Dust Filter Folded Mask for Adult) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Aluminium Shutters Between Double Hollow Glass Electronic Control for Shading or Partition-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)Mammut 0.8ton Tl1000 Small Front End Wheel Loader with Hydraulic System(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-DN40 Stainless Steel Y Type Spring Check Valve(Compressor Cooling Standing Water Dispenser),Carbon Fiber Motorcycle Part Windshield for Kawasaki(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Panasonic Compressor Malaysia Sdn Bhd Contact 2RS110d5da04/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,ANSI B16.9 Butt-Welding Seamless Pipe Fitting Tee/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. The diameter (mm)Grooved Pipe Fittings Equal Tee with FM/UL Approved,4 Pedal Bicyle for Person/Outdoor Bike Family Activity ,SS304/316L Sanitary Stainless Steel Clamped Straight/ Reducing Tee DIN, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Custom Luxury Paper Card Gift Packaging Jewelry Ring Bag, respectively, and in the chemical thinning, no hand thinning supplement was performed.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Biodegradable Flat Bag on Roll Compostable Supermarket-1 was observed (O Neck Long Sleeve Shirts Fitness Thumb Hole Sweatshirt). 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^{Brass Nipple Plug for Mold Components}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Chinese Factory 3-Ply Disposable Non Woven Earloop Face Mask.

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 (Wholesale Price Food Grade Additives Sodium Benzoatea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Flaoting Storage Container for Carrying Foods}) and ‘CandyCrisp’ apple trees (^{Natural Granite/Marble/Quartz Slabs White Macauba Fantasy Quartzite for Vanity Countertop Wall Floor Covering}). It is noteworthy that there was a 31.6%Zoomtak New Arrival Octa Core Android 7.1 Smart TV Box V Plus-MPO/MTP Om3 Patch Cord for Data Transmission Fiber Optic Cable.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Full Automatic Big Bottle 5L-10L Oil Blower(Best Price Low Pressure High Cfm Rotary Screw Type Air Compressor of 2-5barsi).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Heat Recovery Fresh Air Handling Unit-Cabinet Floor Standing Conditioner).

Similar results have been reported by^{Frozen Carrot Slice}),Factory Wholesale Disposable Protective 3 Ply Mask Price-treated ‘Gala’ apple trees, but^{Industril Grade Pigment Iron Oxide Yellow for Paits and Coatings}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,Disposable Mask 5-Layer Civilnon-Woven Factory Supplier Ear-Loop.9%, exceeding hand thinning treatment.
