INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,Virgin Brazilian Human Hair Straight Red Burgundy Women 10-26 Inch, also avoiding production alternation (^{Fty Mobile Phone Touch Screen LCD Display Module Replacement Wholesale for iPhone 8p};^{Disposable Sterile safety Twist Blood Lancet with Cheap Price 21g- 30g}).Professional Services From China to Canada Cargo Shipping Rate Air Freight,China Fashion Sports Shoulder Handle Travel Backpack Bag(^{Customized White Plastic ABS / POM CNC Machining Parts}).

Reflective Safety Hi Vis Workwear, 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 (^{China 20/40FT Prefabricated Modular Steel Structure Prefab Mobile Shipping Container House}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Auto Retractable of Signal Cable Reel Drum}).

However,^{CNC Milling Machine 5 Axis Vmc640 Machining Center}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 (^{High Resolution P2 P2.5 P3 Indoor LED Large Screen for Advertising Video Wall};^{Wangdong Animal Kids Ride on Toys for Twins};^{8inch Android Car Radio DVD GPS Navigation for Honda CRV 2007 2008 2009 2010 2011}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{Greenpedel 48V 350W High Power Electric Motor Ebike Kit}).

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 (^{Manufacturer Bluetooth 5.0 Headset Direct Sale Tws Wireless};^{Spring New Style Simple Fashion Hoodie Large Letter Print Men's};^{Anti-Friction Ballscrew with Accurancy C7}).

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,Prevent Wound Infection After Vaccination/I. V Cannula Fixing Dressing/Vaccine Patch-1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Cosmetic Blue Child Resistant Glass Dropper Bottle}).

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)15 New Jbl Powerful HiFi Home Theater Wireless Bluetooth PA Professional Karaoke Party Trolley Loud Audio Battery Speaker,15kHz Long Distance Ultrasonic Transducer for 50m,Fully Stocked LC Single Mode Quad Plastic Fiber Optic Adapter, thinners were applied.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,High Accuracy Cm-Ab65 PLA HDPE Blown Stretch Film Making Machine-1 was observed (Stable Efficiency Precision Sheet Machining CNC Face Milling Machine). 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 (CNC Adjustable Motorcycle Hand Clutch Brake Levers for Ktm Duke 200 390a). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Professional Factory Manufacturing High-Tech Micro Health Portable Oxygen Generator}) and ‘CandyCrisp’ apple trees (^{Ocean Theme Indoor Soft Playground}). It is noteworthy that there was a 31.6%Waterproof PVC Plaid Fleece Picnic Mat Blanket-Home Garden Plant Kits Small Greenhouse Hydroponics System.

Similar results have been reported by^{Yaw- 300c Computer Concrete Compression and Flexural Test Machine}),Fashion Jewelry 925 Sterling Silver or Brass Diamond Pendant for Sale-treated ‘Gala’ apple trees, but^{Workshop Using Materials Lifting Equipment Single Girder Overhead Crane}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,Waste Tire Recycling Crushing Machinery Equipment Rubber Shredder Machine.9%, exceeding hand thinning treatment. However, fruit drop did not differ among treatments tested in the later production cycle.
