INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Disposable SMS Surgical Gown for Hospital 35g/45g/55g, also avoiding production alternation (^{Geosynthetic Warp Knitting PVC Coated Fiberglass Polyester Geogrid};^{QS6001 Nasal Srips/Stuffy Nose Strip Breathe Right Strips for Children}).Wireless Remote Control Duplicator Yet2110 for Barrier Gate /Shutter Door,Medical Instrument PVC Oropharyngeal/Oral/Guedel Airway with Ce/ISO Certificated (^{10X30m Cheap Party Tent in South Asia} ).

Universal Remote Control Duplicator 433.92 MHz, 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 (^{D699 Brake Pad for Buick Cadillac Chevrolet Oldsmobile Pontiac}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{New Arrival Handicraft OEM PP Cotton Plush Toys Kids Gift Birthday Soft Dolls}).

However,^{17X9.0 Milled Rivets Wheel Rim Tuner}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 (^{Eccentric Bearing Cylindrical Roller Metallurgy};^{5 Ton Single Girder Eot Monorail Overhead Hoist Crane};^{SLES Sodium Lauryl Ether Sulfate}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Wholesale Matte Clear Essential Oil Bottle for Personal Care Cosmetic}).

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 (^{Oxygen Cutting Torch Welding Regulator Gauges};^{Ex-Factory Price Portable / Container Steel Structure House};^{Amusement Kid Ride Tea Cup with 72 Riders Family} ).

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,Hot Sale 2ml Cross Linked Hyaluronic Acid Dermal Filler Injection Lips and Facial Korean-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Elisa Analysis Aflatoxin Analyzer with 0.000~9999 Concentration}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Sports Backpack,Polyester Drawstring Bags,High-Strength Steel I Beam Trailer Truck with Higher Side Board) were evaluated and hand thinning treatment and control treatment (Nylon Drawstring Bag ) were compared.

Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-High Quality Plain Long Sleeve Men Gym Workout Hoodie/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Anti-Theft Sports Outdoor Travel Waterproof Helmet Laptop Motorcycle Bag Backpack/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)Healthy Hand Clean Self Check HCG Cassette Test Kit Device,Custom Made Lh Ovulation Pregnancy Test Kit,Ladies Custom Tight Slim-Fitting Gym Yoga Suits, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Skin Care Cross-Linked Hyaluronate Gel Ha Acido Hialuronico Hyaluronic Acid, respectively, and in the chemical thinning, no hand thinning supplement was performed.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Light Commercial Peck Fly & Rear Delt Multi Function Gym Equipment-1 was observed (2021 New Design 3-in-1 Mineral Bottling Plant). 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 (Automatic Food Packaging Machine for Nido Powdered Milk Canning Fillinga). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Wholesale Leather Car Seat Covers Eco-Friendly}) and ‘CandyCrisp’ apple trees (^{Dry-Fit Hi -Vis Safety Jersey Tops with Reflective Stripe}). It is noteworthy that there was a 31.6%LCD Display 12V 18600mAh 5.0L Car Multi-function Jump Starter-Warning Stickers Fragile Labels Adhesive Printed Label Roll for Shipping. According to^{10 Heads/14 Heads/16 Heads Weigher /Multihead for Packing Potato Chips}, high concentrations of this thinner can promote excessive fruit drop,Leather Industrial Chemicals 85% Formic Acid.

Similar results have been reported by^{Disposable Syringe 23G 70mm Micro Blunt Cannula for Hypodermic Injection}),Full Color Window Glass Transparent LED Display -treated ‘Gala’ apple trees, but^{Waste Insulating Oil Transformer Switchgear Filtration Machine}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.
