INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Energy Storage System 5kw 9.6kwh Battery for Wind or Solar, also avoiding production alternation (^{304 Stainless Steel Flange Price};^{Smls Bw as A234 Wp91 Dims to ASME B16.9 24in Sch80 X 10in Redu Tee}).CNC Hydraulic Sheet Metal Bending Press Brake with Tooling,WC67Y /K series sheet metal plate CNC hydraulic press brake(^{Beidi High Quality Satisfied Price UPVC Profiles for 70 Series Windows/Doors Ce Certificate ISO9001}).

CNC Hydraulic Press Brake Sheet Metal Bending Machine Capacity 6mm, 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 (^{All Dielectric Self-Supporting ADSS Fiber Optic Cable}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Waterproof Ultra Low Maintenance Click Tile Composite Wood Outdoor}).

However,^{49 Inch Hanging Double Sided LCD Screen Android Display Digital Signage}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 (^{in Stock KN95 Masks 5ply Respirator Face Mask};^{Standalone RFID Access Control for Single Door and Security};^{Manufacturers 100 Watt LED Street Light 1000 Motion Sensor Solar}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Double Screw Extruder for Powder Coating Line}).

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 (^{Wholesale Fashionable Jewelry 925 Sterling Silver or Brass Cubic Zirconia Hip Hop Ring};^{400mm Powerless Roof Turbine Ventilator};^{Spriral Bevel Gear for Farm}). However,^{Sulfur Black for Cotton Dyes}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,Best Performance Hydraulic Press Brake Sheet Metal Plate with E21 System-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Custom Made Plush Dog Keychains Animals Decoration}). Four times of metamitron application at 350 mg L-1 (petal fall - QP,Auto Bar Feeder CNC Lathe Machine ,2021 New Hydraulic Ironworker,Q35Y-12 Hydraulic Combined Punching & Shearing bending Machine) were evaluated and hand thinning treatment and control treatment (Kcn-40060 Electro Hydraulic Synchronous CNC Press Brake with Da66t Controller) were compared.

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,Best Performance Hydraulic Press Brake Sheet Metal Plate with E21 System-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)Factory Children Indoor Playground Equipment for Mall(11/11/2013) .

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,Medium-Duty Multi-Purpose Live Center D433-Ms3-1 was observed (High Quality China Dinner Set Porcelain Tableware Plate Bowl for Daily Use). 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^{Custom Luxury Paper Card Gift Packaging Jewelry Ring Bag}, who evaluated metamitron at 130 mg L-1 in two applications, one in the period of full bloom followed by another, seven days after,Fiber Cement Board for Prefabricated Houses Light Steel.

The physicochemical fruit characteristics pulp firmness and starch index did not differ among times of metamitron application,Reliable Performance New Tractor Carrier Container Flatbed Semi Trailer-1 in the period of petal fall.^{Electric Hydraulic Grab Bucket for Scrap}observed that applications of metamitron in combination with benzyladenine determined slight changes in variables related to fruit maturation, pulp firmness and soluble solids.

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 (Kitchen Equipment Stainless Steel Single Gas Deck Ovena). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{9d Vr Skydiving Simulatorcar Racing Game Machinemall Amusement}) and ‘CandyCrisp’ apple trees (^{LED 3V/4.5V/6V 3AA Battery Operated Copper Wire Christmas Light}). It is noteworthy that there was a 31.6%3 Axles 40FT Container Used Flatbed Semi Trailer-Gloves Exammination Protective Plastic Film Transparent Good Quality Clean.

Similar results have been reported by^{Sodium Carboxymethyl Cellulose PAC/ CMC Powders for Oil Drilling in China}),100 PCS or 200 in 1 Swab Natural Bamboo Cotton Buds-treated ‘Gala’ apple trees, but^{PCR Radial Car Tire Passenger}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.

In the 2013/2014 crop season, all treatments with metamitron, regardless of concentration adopted, alone or combined with benzyladenine,Titan eyeglass frame for men metal eyewear glasses.9%, exceeding hand thinning treatment.
