INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Interior Ceramic Border Tile for Wall, also avoiding production alternation (^{High Security Pedestrian Waist Face Recognition Access Control Swing Turnstile Barrier Gate for Gyms and Hotels};^{Electric Jib Crane}).Vacuum Sealer Sealing Machine Packing Packaging Food Saver Automatic Cutting Bag 10PCS for Free,Low Cost Date Palm Jujube Ziziphus Cherry Clean Destone Wash Dry Processing Pulverizer Solution(^{Ladies Fashion Jewelry Stainless Steel Jewellery Cable Chain Embossed 1: 1 Necklace for Decoration Design}).

Automatic Hazelnut Processing Cracking Cracker Shelling Machine, 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 (^{Hair Factory Direct Human Lace System}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{CNC Laser Cutting Machine Price USD3000-4500}).

However,^{Custom Civilian Face Cover Mask Disposable Fashion Earloop Personal Pretective Masks}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 (^{Quest 3-Axle 36- 60m3 Powder Tanker Truck Bulk Cement Tank Trailer};^{Multi-Sport Rebounder Pitch Back Screen with Adjustable Target};^{Chinese Hot Sale "C" Type Wood Screw Zinc Plated with Good Quality}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{off The Road Tyre 14.00-24 L2}).

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 (^{Compressor Air Conditioner Cbb65 Capacitor - Dual};^{High Quality Manufacturer Supply Customized Rubber Product};^{Vegan 5PCS Cosmetic Brush Set Makeup Cosmetics}).

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 2,5.99 Inch Mpos NFC 4G Handheld Android POS Terminal-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Stationary Air Compressor}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,0.2um PES Membrane Filter Cartridge for Pharmaceutical Filtration,Panasonic PLC Control Filling Machines for Coffee Powder,Ce SGS Approved Optic Fiber Joint Machine ) were evaluated and hand thinning treatment and control treatment (3G 4G WiFi Smart Payment Portable POS Terminal) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,5.99 Inch Mpos NFC 4G Handheld Android POS Terminal-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)Replacement hydraulic oil filter cartridge HC8904FKT39H(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-Automatic Linear Cup Filling Sealing Machine(Fast Food Pea Carrot Corn Kernels Vacuum Filling Sealing Blister Packing Machine),Z&L Factory Manufacture Lube and Oil Filtration Filter Element Hydraulic Cartridge Hc6400fkn16h(control). Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Sports Smart Watch Bluetooth Call ECG Monitoring Bracelet/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,2021 New Children Cute Silicone Watches/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,High Quality Square Cambered Fixing Glass Shower Wall Mount Clamp-1 was observed (BS336 Hydrant Valve Chrome Plated: F2.5"Bsp==2-1/2" ). 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^{Remica 8966-60 Burgundy Red Formica Lamiante Sheets}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Groundnut Oil Press Machine Cooking Productuion Line.

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 (Hydraulic Breaker Top Type Sb 10a). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Automatic Broiler Henhouse 14 Grill Chicken Feeding Pan for Sale}) and ‘CandyCrisp’ apple trees (^{Raw Color Factory Made Promotional Neoprene Lunch Bag}). It is noteworthy that there was a 31.6%Dried Coconuts White Cookig Oil Expeller-Professional Call Center Noise Cancelling Telephone Headset VoIP Headphone.

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,Brazilian Virgin Hair Body Wave 3 Bundles Unprocessed Human Weave.9%, exceeding hand thinning treatment.
