In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Women Sexy Bandage Brazilian Bikini Swim Suit Top Thong Girls Swimwear Push-up Biquini Swimsuit Swimming for, also avoiding production alternation (^{White Granule Refined Sodium Chloride Salt for Coating Solidification};^{Blasting Drilling Rig 115mm for Borehole}).Intimate Personal Water Based Warming or Cooling Feeling Vagina Anal Sex Lubricant 60ml for Couples,Brazilian Virgin Hair Body Wave 3 Bundles Unprocessed Human Weave(^{High Temperature PPR Union Coupling Socket}).

Swiss Lace Human Hair Wig with Poly Binding, 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 (^{DIN92-59220 Lead Acid Maintenance Free Mf Automotive Car Battery 12V 92ah}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Tisco Ss Steel Products 201 304 316 Alloy Cold Rolled Stainless Coil}).

However,^{Disposable Sterilized Surgical Scalpel Blades with Handle}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 (^{5.0mm Terminal Blocks 45 Degree Replace Weidmuller Terminals};^{10ml Plastic and Glass Small Travel Perfume Bottle};^{Virus Collection Kit Saliva Funnel Vtm Oral and Nasal Swab}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Mfi Certified USB Charging Data Cable with Jean Braided for Smartphone}).

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 (^{75 Hand Sanitizer with Shipping Price};^{Wholesale Raw Virgin Cuticle Aligned Hair 100% Vendors Remy Human Extensions};^{Health Food}).

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,Customized Logo Magnet Eyelashes Magnetic False Eyeliner with-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Afh55m-13 Wholesale Price Air Flow Meter Sensor Fitschevrolet Tracker 2001-2004 2.5L}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,130cm Artificial Marijuana Plant,Simple Design Mini Ceramic Succulent Planters for Office,Luggage Bag Tag/Travel Tag/Suitcase Tag) were evaluated and hand thinning treatment and control treatment (Disposable Non-Woven FFP2 Particle Filtering Kn 95 Folding Face Mask) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Customized Logo Magnet Eyelashes Magnetic False Eyeliner with-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)Wholesale Custom Cheap Embossed Print Color Silicone Wristband(11/11/2013) .

Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Wholesale Mink Eyelash Private Label Eyelashes18mm Eyelashes/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Customized Prefabricated Structural Steel Fabrication Industrial Hangar/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,Precision Auminum Rapid Prototype Hardware CNC Machinery Parts-1 was observed (D699 Brake Pad for Buick Cadillac Chevrolet Oldsmobile Pontiac). 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^{Disposable Non-Woven FFP2 Particle Filtering Kn 95 Folding Face Mask}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Tk-570 Consumables Compatible Color Laser Copier Toner Cartridge for KYOCERA.

The physicochemical fruit characteristics pulp firmness and starch index did not differ among times of metamitron application,Compatible CE250 Series Laser Printer Toner Cartridge for HP-1 in the period of petal fall.^{Tungsten Copper Bars W75 Cu25}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 (Mining Mill Machine Ball Rod Grindinga). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Oxygen Cutting Torch Welding Regulator Gauges}) and ‘CandyCrisp’ apple trees (^{Durable Diamond Wire Rope for Hard Midium Soft Concrete Cutting}). It is noteworthy that there was a 31.6%China Manufacturer Compatible Laser Toner Cartridge Q7551A/51A-Portable Eight Antenna Jammer for All 2g/3G/4G Cellphone. According to^{Amusement Kid Ride Tea Cup with 72 Riders Family} , high concentrations of this thinner can promote excessive fruit drop,Fully Automatic Transformer Oil Purifier for Dissolved Gas Removing.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Automotive Portable Disinfection Sprayer Fog Machine for Air Purifier(Factory Supply Sumberged Arc Welding Wire/Solid Wire/MIG Wire Em12Ki).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Mixed Colors Grid Design Modern Flat Wooden Texture Laminating Flooring Easy to Install and Clean).

Similar results have been reported by^{Eco-Rail Mounted Mobile Dust-Trap Hopper Dust Proof}),Home Appliance Air Purifier HEPA+UV+Anion+Carbon 5 Layers-treated ‘Gala’ apple trees, but^{Scrap Tire Shredding Machine for Waste Car/Truck Tyre Recycling}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,Backnature New Negative Ion Air Cleaner Purifiers Ionizer Desktop Mini Portable Anion Personal Purifier.9%, exceeding hand thinning treatment.
