INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,2 DIN Car Stereo MP5 FM Transmitter Navigation Audio Player, also avoiding production alternation (^{49 Inch Hanging Double Sided LCD Screen Android Display Digital Signage};^{in Stock KN95 Masks 5ply Respirator Face Mask}).4+64GB Android 10.0 Car Multimedia Player for Chevrolet Aveo 2011-2021 GPS Navi Radio Stereo IPS Touch Screen Head Unit,Top Quality Rename GPS Version Tws Wireless 1: 1 for Aipods PRO 3 Earphones Headphones Earbuds(^{Standalone RFID Access Control for Single Door and Security}).

High Quality Hollow Design Customized Avalible Wedding Invitation Card, 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 (^{Manufacturers 100 Watt LED Street Light 1000 Motion Sensor Solar}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Recycled Breathable Polypropylene Non Woven Drawstring Backpack}).

However,^{Fashion Jewelry 925 Sterling Silver or Brass Diamond Pendant for Sale}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 (^{Ceramic Fiber Insulation Blanket 1400c for Forges};^{Walkie 1.5t 1500kg Scale Electric Pallet Truck};^{Wholesale Fashionable Jewelry 925 Sterling Silver or Brass Cubic Zirconia Hip Hop Ring}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Objects at Acupoints of Body Sandwiched Moxibustion}).

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 (^{Original Brand Mobile Phone D802 Great Smartphone Hot Sale Cell};^{Professional Tailors Dummy Tailoring Mannequin for Making & Fitting Clothes};^{Natural Dry Sweet Paprika Granules Powder}).

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,GSM 1900 Signal Repeater -1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Best Sale Factory Direct Indoor Playground Equipment}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,23dBm Dcs 1800MHz Signal Booster /Repeaters /GSM Repeater ,Hot Sale New Design Christmas Greeting Card,Imee Peacock Three-Dimensional Creative Postcard Greeting Card for Friends and Colleagues) were evaluated and hand thinning treatment and control treatment (American Countries Black Dual Band Booster 4G AGC Mgc 70dB 23dBm 3G Signal Amplifier 1900 Repeater 700MHz) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,GSM 1900 Signal Repeater -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)Floor Trap (11/11/2013) .

In the 2013/2014 crop season, treatments were applied on 10/22/2013,Color Custom Multi-Cylinder Diesel Engine for Pump Generator Set/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)Good Quality Linear Stage Module for Laser Cutting,Made in China 40HP 4WD Agricultural Machinery Tractor,3.5 Inch LCD Driver IC Hx8238d 54pin Touch Screen, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)30 Years Manufacturing Experience Forged Steel Ball, respectively, and in the chemical thinning, no hand thinning supplement was performed.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Professional Fishing Equipment Nylon Net Decorative-1 was observed (Tendrillar Page). 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 (Cheap PVC Waterproof Home Decoration 3D Wallpaper Stonea). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{China Eltrical Hose Crimping Machine 2inch to Malaysia}) and ‘CandyCrisp’ apple trees (^{New Design Polyresin Hanging Gnome Figurine for Panters}). It is noteworthy that there was a 31.6%Mother and Baby Recycling Granulation Machine/Mother Pelletizing Machine-Reusable Barware Water Cup Coffee Tumbler Beer Glass Whiskey. According to^{Sale Dark Green Silk Screen Printing Spray Electroplating Deep Processing Glass Wine Bottle Baked}, high concentrations of this thinner can promote excessive fruit drop,Full Body Support Well-Rested Wave Shape Latex Foam Mattress.

Similar results have been reported by^{Womens Flat Sandals Shiny Beads Design T-Strap Slip-on Elastic Dress Summer Beach Casual Esg13682}),11oz Standard Ceramic/Porcelain Coffee Mugs for Sublimation with Logo Custom-treated ‘Gala’ apple trees, but^{Stripe Microfiber Quick Dry Double Side Brushed Soft Sport Towel}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.
