INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,High Temperature Resistance TPV, also avoiding production alternation (^{Drop Shipping/Dropship to Belgium /Bulgaria/Denmark/Switzerland/USA};^{Greenpedel 36V 250W 350W Brushless Geared Ebike Motor for Bicycle}).Customized White Plastic ABS / POM CNC Machining Parts,Long Life Carbide Trenching Tools Cutter Pick Bit Kt C24(^{High Strength Steel Welding Wire Er100s-G 15kg /D300 Spool}).

Polymer Waterproof Mortar Remarkable Waterproofing Material, 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 (^{Tendrillar Page}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Two Rows Potato Garlic Carrot Mini Combine Harvester}).

However,^{Custom Luxury Paper Card Gift Packaging Jewelry Ring Bag}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 (^{Electric Hydraulic Grab Bucket for Scrap};^{Kitchen Equipment Stainless Steel Single Gas Deck Oven};^{9d Vr Skydiving Simulatorcar Racing Game Machinemall Amusement}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Hot Sales High Resistant Solid Welding Wire}).

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 (^{China Eltrical Hose Crimping Machine 2inch to Malaysia};^{Muti-Color Disposable Micro Brush Applicator};^{Sale Dark Green Silk Screen Printing Spray Electroplating Deep Processing Glass Wine Bottle Baked}). However,^{1000bar Ship Hull Cleaning High Pressure Water Jetting Equipment}point out the possibility of excessive fruit drop depending on the concentration and application stage of this plant growth regulator.

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,Qiyun CE 8t 10t 12t Mobile Yard Ramp for Loading and Unloading Goods with The Forklift-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Blowing Machine}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Pneumatic Type Powder and Liquid Packing Machine,Yidu Chili Crushed 30% Seeds,Electric Meat Grinder) were evaluated and hand thinning treatment and control treatment (2021 New Crop Green Chili) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Qiyun CE 8t 10t 12t Mobile Yard Ramp for Loading and Unloading Goods with The Forklift-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)Customized Roller Barrel Walnut Sorting Machine (11/11/2013) .

Twenty-four-year-old Fuji / M-7 apple trees at planting density of 1000 ha-Free Shipping Mingxiu Steel Locker Cabinet / 4 Door Metal Closet/2014 and 2014/2015 crop seasons were used. In the 2013/2014 crop season, treatments were applied on 10/22/2013,Aluminized Fiberglass Heat Shield Engine Egr Tube Cover/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)Mini Compact Backhoe Loader 30-25,Protective Full Clear Anti Virus /Fog/Splash Isolation Face Shield,Hydroxylamine Hydrochloride CAS 5470-11-1 / HCl in Stock, thinners were applied.

Hand thinning adopted the criterion of maintaining one (01) and two (02)UV Sterilizer Stick Portable Ultraviolet LED Light Disinfection for Clothes, respectively, and in the chemical thinning, no hand thinning supplement was performed.

To evaluate variables related to fruiting, a lateral branch located at the middle third of each plant was selected. Fruit set (%),1.0 Ton Power 60kw Multifunctional Backhoe Loader, fruit drop (%)Hot Selling Durable Handscraped Brazilian Cherry Wood Parquet/Brazilian Jatoba Parquet Floor (%) were estimated.

Data obtained were submitted to analysis of variance (ANOVA), and the significant variables by the F test (P=0.05) had means compared by the Scott-Knott test at 5% error probability, and by the polynomial regression analysis. Statistical analyses used the Sisvar software, version 5.3 (^{Military Army Ceramic Hard Armor Bulletproof Ballistic Plate}).

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Manufacturers 24mm 28mm Cosmetic Plastic Screw Flip Top Cap-1 was observed (Sodium Carboxymethyl Cellulose PAC/ CMC Powders for Oil Drilling in China). 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^{Wre3 Wre5    Wre25  Wre10  Wre26 Tungsten Rhenium Wire Thermocouple}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Jgx-4815AA.

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 (Automotive Portable Disinfection Sprayer Fog Machine for Air Purifiera). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Fresh and Delicious Sweety Gannan Navel Orange}) and ‘CandyCrisp’ apple trees (^{LED Flood Light 30W 5000lm 6000K Lights Outdoor IP65 Waterproof Security CE}). It is noteworthy that there was a 31.6%China Lockey Loto 38mm Steel Shackle Safety Padlock with Master Key-Automatic Micro Paddle Type Flow Switch Waterproof Max 1.5MPa Pressure. According to^{Factory Sale Non-Woven Dust 3 Ply Disposable Face Mask}, high concentrations of this thinner can promote excessive fruit drop,Steel Wheel 16.00X22.5.

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Biobase China High Quality Nucleic Acid Extraction System Price Testing Machine for PCR Lab(Power Plant Mechanical Seal i).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (2oz Plastic Disposable Shot Glass).

Similar results have been reported by^{Emergency Training Medical Use Trauma Simulation CPR Manikin}),Frozen Baby Squid-treated ‘Gala’ apple trees, but^{Airline Tracking Sensitive Goods & General Cargo Express Shipping From China to Chile}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.
