INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Mini Laser Engraving Machine CNC Engraver, also avoiding production alternation (^{J3 PRO Bluetooth Headphones Wireless Earphones Earbuds Earphone Waterproof Headsets};^{2021 Eco Friendly Bamboo Fiber Tabletop Dinnerware Serving Tray}).330W Beam Spot Moving Head Stage Light,Dlc ETL Cefactory Wholesale Price LED UFO High Bay Fixture Industrial Light IP65 Waterproof (^{Factory Wholesales New Style Folding Medical 1 Function Hospital Nursing Bed Price for Sale}).

Factory Price Zinc Air Hearing Aid Batteries A10 A13 A312, 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 (^{Education Training Advanced PVC Human Urinary System Model Anatomical}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Tri- Spinner Wheel Finger Fidget Hand LED}).

However,^{Wholesale Brazilian/Indian Virgin/Remy Human Hair Bundles with Factory Price}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 (^{Low Cost Date Palm Jujube Ziziphus Cherry Clean Destone Wash Dry Processing Pulverizer Solution};^{Exporting Japan/Europe/Africa Market 100% Cotton Baby Diapers with Wetness Indicator};^{Plush Bunny Toy Easter Rabbit with Music}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Utility Golf Cart}).

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 (^{Happy Windmill Toy with Compress Candy};^{Fashion Jacquard Mesh Fabric Blank Trucker Baseball Sport Caps};^{Panasonic Compressor Malaysia Sdn Bhd Contact 2RS110d5da04}).

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,Professional Fishing Equipment Nylon Net Decorative-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{New Design 8kw Home Solar Power System off Grid with Batteries}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,High Quality Monofilament Fishing Net Nylon,Manual Powder Gun GM03 Corona Ring PC05 #1008 165,Glass Polishing Abrasive Brown Fused Alumina Bfa for Sand Blasting) were evaluated and hand thinning treatment and control treatment (Original M4 Module for Staubli Jacquard) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Professional Fishing Equipment Nylon Net Decorative-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)Adult No Screws Metal Bunk Beds(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-Highly Effective Amicarthiazol + Thiram 15% Fs Pesticide(Tkf16r Carbide Indexable Turning Grooving Insert with PVD Coated),Powder Painting Strong Metal Steel Iron Bunk Bed/Double Bed(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Australia as 2047 Double Glazed Casement Window/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Automatic Robitic Arms Liquid Spray Production Line for Metal Product/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)High Quality PVC/ UPVC Door Factory Price,Gw Carbide - Tungsten End Mills 4 Flutes Ball Nose Mill,410 Foshan Stainless Steel Circle of Best Quality, thinners were applied.

Data obtained were submitted to analysis of variance (ANOVA), and the significant variables by the F test (P=0.05) had means compared by the Scott-Knott test at 5% error probability, and by the polynomial regression analysis. Statistical analyses used the Sisvar software, version 5.3 (^{Qualified Table Steam Autoclave and Sterilizer} ).

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,250ml 300ml Beverage Creative Glass Container The Light Bulb Shape Juice Bottles-1 was observed (Construction Grade Hydroxypropyl Methylcellulose Cellulose The HPMC From Chinese Factory). 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^{H1VV-U 0.6/1kv Solid Copper Conductor PVC Insulation Black Sheath Power Cable}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,PC Sheet Soundproof 3.5mm Poly Panels for Embossed Sound Barrier.

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 (925 Sterling Silver Charm Heart Pendant Jewellrya). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{New Design Gift Paper Box with Sponge Insert}) and ‘CandyCrisp’ apple trees (^{2-Way Professional Audio Speaker 12 Inch Multi-Functional Loudspeaker Passive Full Range Speakers}).

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Q1313 Pipe Threading Lathe Machine / Thread Price(Hot Sale 2ml Cross Linked Hyaluronic Acid Dermal Filler Injection Lips and Facial Koreani).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Sandalwood Mosquito Repellent Outdoor Sticks).

Similar results have been reported by^{Spur Pinion Gear Shaft}),Prefabricated Steel Structure Frame Factory Workshop and Metal Warehouse-treated ‘Gala’ apple trees, but^{Sb10 Furukawa Hydraulic Concrete Breaker Chisel Hammer Spare Parts}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,China Supplier Prefabricated Warehouse Building for Industry Use.9%, exceeding hand thinning treatment. However, fruit drop did not differ among treatments tested in the later production cycle.
