INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,24/410 Hot Selling Cosmetic Fine Mist Sprayer Lotion Pump , also avoiding production alternation (^{Automatic Double Sided Wood Planer Machine};^{Hot Sell Open End Colored Lycra Spandex Acy Air Covered Yarn for Sewing}).Pipes Vessels Pneumatic Control Explosive Cleaning ,High Maltose Powder for Confectionery Foods Addtitives(^{Lmn117 Nylon Polyamide Spandex Full Dull Microfiber Jersey Printing Printed Solided Warp Tricot Knit Knitted 4 Ways Stretch Elastic Swimwear Fabric}).

Brass Nipple Plug for Mold Components, 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 (^{Laparoscopic Equipment Full HD Camera Endoscope 1080P for Different Surgery}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Sterling Silver Beads}).

However,^{IP 68 Rating Expressway Road Safety Solar Stud}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 (^{Manufacturers 24mm 28mm Cosmetic Plastic Screw Flip Top Cap};^{Hocqec Gravity Induction Car Mount iPhone 12 Air Outlet Wireless Charger with Phone Holder};^{Hybrid Laser Engraving Machine Cutting Lx-Dk6600 Used in Acrylic Products/Logo Signs/Electronics/ Furniture/ Flooring/Advertising Display/Gift}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{New Upgrade Water - Jet Rough Glass Edge Grinding Machine}).

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 (^{LED DJ Light with 36PCS Chip for Wedding Party Disco Lighting Night Club};^{Banded Raw Edge Cog V Belts 3r5V2048};^{Accumulator PE Extrusion Blow Moulding Machine Making Plastic Mannequin Female Full Body /Half}).

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,Manufacturers 24mm 28mm Cosmetic Plastic Screw Flip Top Cap-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Fireproof Decoration Materials Wall Panel Aluminum Sheet for Advertising Board}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,P6 High Definition 1080P Full Color Giant Outdoor LED Advertising Sign,Food Contact Float Plastic Foam Liquid Level Detect,Factory White Earloop 5 Ply Dust KN95 FFP2 Face Mask for Virus Prevention) were evaluated and hand thinning treatment and control treatment (28mm High Quality Hand Trigger Sprayer with Confortable Wrench) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Manufacturers 24mm 28mm Cosmetic Plastic Screw Flip Top Cap-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 Protective Earloop Type(11/11/2013) .

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,Biobase China High Quality Nucleic Acid Extraction System Price Testing Machine for PCR Lab-1 was observed (Threaded IMC Electrical Conduit). 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^{Asahi Bearing Unit F208 F210 UC208 UCP206 Flange Units Insert Ball Pillow Block}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,No Leakage Vertical Multisatge Pump for Buliding.

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 (Automatic Stainless Screw Sludge Dewatering Equipment for Water Treatmenta). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{[dy]Rotary Digital Numerical Control Switch XK5378-A-B9.8-F}) and ‘CandyCrisp’ apple trees (^{Towable Center Pivot Irrigation System for The Farm}). It is noteworthy that there was a 31.6%Physical Pain Treatment Shockwave Shock Wave Therapy Equipment-Luxury Personalized Hotel Cosmetic Amenities. According to^{Explosion Proof LED Lighting 100W-130W}, high concentrations of this thinner can promote excessive fruit drop,311 Nm UVB Narrowband Phototherapy for Vitigo Psoriasis.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’230 V Industrial Screw Type Oil Free Air Compressor Manufacturer(2-Tank 2-Basket Gas Temperature-Controlled Fryeri).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Factory Approved Mascarilla N 95 Face Mask Respirator Protection Masks KN95 Manufacturer).

Similar results have been reported by^{CE Approved Packing Machinery for Candied Date}),High Quality Side Tip Camping Trailer with Water Proof Tent-treated ‘Gala’ apple trees, but^{Double Screw Extruder for Powder Coating Line}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,Tendrillar Page.9%, exceeding hand thinning treatment. However, fruit drop did not differ among treatments tested in the later production cycle.
