INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Manufacturer Wholesale Jewellery 18K Gold Plated Necklace Cable Chain with Flower Embossed for Jewelry Craft Design DIY, also avoiding production alternation (^{Professional Indoor Gym Equipment / Seated Leg Press};^{Fine Dinnerware Tableware Porcelain Sets12PCS Pad Printing for Wholesale with Discount Price}).Ladies Fashion Jewelry Stainless Steel Jewellery Cable Chain Embossed 1: 1 Necklace for Decoration Design,Fashion Accessories Cable Chain Beads Bracelet Earring Necklace for Jewelry Gift Wholesale(^{Raw Material PVC Resin Sg5 K66 K67 K65 in Plastic}).

316L Stainless Steel Figaro Chain, 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 (^{Dog Cute Print Porcelain Barrel Cup with Handle for Drinkware}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{R Shape Ferrite Rod Core Choke Coil Inductors for LED Light}).

However,^{9.7 Inch Android Quad Core Tablet PC with Built-in 3G and HDMI Input}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 (^{Hot Sale PU Plastic Road Speed Bumper Hump};^{House Designs Prefabricated Two Bedroom K Type Heat Proof Fabricated Homes};^{Cut-Resistance Flame Retardant Aramid Knitted Fabric}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Precision Hardened Steel Ejector Guide Ball Cage Bushing}).

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 (^{Floor Trap} ;^{Compressible Offset Printing Blanket for High Speed};^{Food Grade Cooking Oil Packing Machine with Ce}).

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,Ship Rubber Balloon-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Kitchen Countertop White Semi Precious Stone Slab}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Whole Fly Fishing Rod 11FT 4PC 6/7wt Carbonfiber Switch,Innovative Waterproof Outdoor Walnut Color WPC Board Composite Decking,Matchless Colourfast Technology Contemporary WPC Decking) were evaluated and hand thinning treatment and control treatment (Classic Men's Pullover Hoodie in Burgundy) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Ship Rubber Balloon-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)Baltic Rib 470 B Deep V Inflatable Fishing Yacht China Large Pontoon Boats(11/11/2013) .

Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-5m/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,for Sale 4.2m Rib Boat with FRP Bottom/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)Custom Made Artificial Stone Solid Surface Bathroom Countertop,French 52 in Black Resin Stone Free Standing Corner Bath Tub,Exporting Japan/Europe/Africa Market 100% Cotton Baby Diapers with Wetness Indicator, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Hydraulic Assembly Rubber Hose Carbon Steel Flexible-1 was observed (Yinherb Lab Citicoline USP Standard 98% Cdp Choline Sodium). 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. The mean fresh fruit weight increased with the application of 350 mg L-1 metamitron in the petal fall phase compared to the other treatments,R1 a 1st R2 2st Hydraulic Hose Factory.

These data are similar to those obtained by^{Apply to Sandvik CV Series CV117 VSI Vertical Shaft Impact Crusher Spare Parts Rotor Tip Set}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Factory Wholesale Electric  Surfboard  with Good Price.

The physicochemical fruit characteristics pulp firmness and starch index did not differ among times of metamitron application,Slanna 2021 Autumn Winter Sexyl Ladies High Waist Casual Hot Shorts Corduroy-1 in the period of petal fall.^{Classic Men's Pullover Hoodie in Burgundy}observed that applications of metamitron in combination with benzyladenine determined slight changes in variables related to fruit maturation, pulp firmness and soluble solids.

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 (Plastic Sheet Extruder Extrusion Extruding Machine for PP/ PS/ Pet/ HIPS/ PEa). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Heavy Hex Nut ASTM A194/A194m ASME SA194/SA194m Grade 2h 8 8m}) and ‘CandyCrisp’ apple trees (^{Promotion Artificial Gift Swing Human Skeleton Model}). It is noteworthy that there was a 31.6%Water Inflatable Racing Surf Board Sup Paddle for Adult-Camouflage Computer Shoulder Schoolbag Outdoor Sports Backpack Bag. According to^{High Quality Square Cambered Fixing Glass Shower Wall Mount Clamp}, high concentrations of this thinner can promote excessive fruit drop,Filling and Sealing Equipment.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’3000-4000bph Full Automatic Blowing Moulding Bottle Machine(Xb2-Bd21 Standard Handle Selector Push Button Switchi).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Factory 10ml/30ml/50ml/60ml/100ml Glass/Plastic Bottle Juice for EGO /Vaporizer/Vapour/Vaping/Vape/Vapor/E Smoke/Smoking/Cig with Competitive Price).

Similar results have been reported by^{Camping Tent2012}),Sludge Dewatering Equipment for Reclaimed Water Better Than Belt Press-treated ‘Gala’ apple trees, but^{HD P6 P5 Full Color Indoor Fixed LED Sign Board}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,700ml/23oz Custom Logo Clean Plastic Tritan Cycling Sport Water Bottle with Directly Drinking Lid.9%, exceeding hand thinning treatment.
