In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Inflatable Board Stand up Surf, also avoiding production alternation (^{Meanwell APC-16-350 Constant Current 350mA IP42 With 2 Years Warranty 16W Single Output Switching Power Supply};^{Auto Parts Rubber Suspension Bushing/Bush for Peugeot 204}).Russia Wholesale High Quality Best Taste Qst Pods Both for Full and Empty Pen Disposable Vape Rick Morty Flex 1600,L12 Digital Display Wireless Headset Tws Bluetooth 5.0 X15(^{Mini PC Standard Windows XP Embedded}).

Factory Wholesale Electric  Surfboard  with Good Price, 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 (^{Mining Tunnel Zwy-60/30 L0 G1 Hydraulic Power Diesel Engine Crawler Mucking Loader Manufacturer}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Samsung LTI550HN12 video wall display panel with cable}).

However,^{Dtp606090 Solar Lithium Battery 3.7V Polymer 4000mAh Lipo Batteries}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 (^{1000ml Disposable Fast Food Bagasse Meat Tray with Lid};^{Ce & RoHS Driverless AC110V or AC220V 1.5W/ 3wled Module};^{Hydraulic Combined Angle Steel Punching and Shearing Machine}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Removable Injection Barrel Thermal Jacket}).

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,Sport Bluetooth Earphone Wireless Headphones with Mic-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Metal keychain with Leather Belt in Black}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,500ml Factory Price Antiseptic 99.9% Efficient 75% Alcohol Private Label Hand Sanitizer,Customized Full Package 900mAh 1800puffs Vaporizer 6ml Disposable Vape,Upgrade Models Rechargeable LED Dust Masks Glowing Color Carnival Lit Party Christmas Mask Gauze) were evaluated and hand thinning treatment and control treatment (Magnetic LED Flashing Clothing Badges) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Sport Bluetooth Earphone Wireless Headphones with Mic-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)Juice/Honey Aseptic Bottling Machine(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-330ml Empty Aluminum Beer Cans(GCP-12A 12heads Automatic Sweet Liquor Filling Line Machine),3000-4000bph Full Automatic Blowing Moulding Bottle Machine(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Sludge Dewatering Equipment for Reclaimed Water Better Than Belt Press/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,700ml/23oz Custom Logo Clean Plastic Tritan Cycling Sport Water Bottle with Directly Drinking Lid/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)Fashion Printed Debossed Sets Woven Silicone Elastic Watch Wristbands for Sales,16oz ,Two Layers Co-Extrusion PE Film Blowing Machine for Packing Bag, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,C45 Hardened Teeth Spur Gear-1 was observed (Happy Windmill Toy with Compress Candy). 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.

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 (Fashion Lady PU Leather Shoulder Bag Messenger Leisure Wholesale Handbag Replica a). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Construction Grade Hydroxypropyl Methylcellulose Cellulose The HPMC From Chinese Factory}) and ‘CandyCrisp’ apple trees (^{10 Ton Ice Making Machine/ Flake Machine}).

Similar results have been reported by^{One Piece Bow Spring Casing Centralizer for Well Drilling}),Military Army Ceramic Hard Armor Bulletproof Ballistic Plate-treated ‘Gala’ apple trees, but^{Ai Smart Home Security Auto Tracking PTZ WiFi Onvif APP PC Web Babysitter Monitor Alarm System Mini IP CCTV Camera}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.
