INTRODUCTION

In apple crop, thinning aims to reduce fruit set, particularly in years where climatic conditions favor excessive floral induction,UL5107 High Voltage Temperature Resistance Heating Wire, also avoiding production alternation (^{High Quality Zipped Movable Cover Thicker Set 3 Foam Pet Dog Bed};^{Latest Hot Sale Clear Black Design Logo Printing Shoes Men Slipper}).Luxury Executive Commercial Leather Office Chair ,Disposable Nonwoven Earloop 3 Ply Medical Mouth Cover Face Mask(^{DMS-59 Male to Dual 2 DVI 24+5 Female Splitter Extension Cable for Graphics Cards & Monitor}).

4K UHD FHD IPTV 8000+ Live 10000+ VOD UK USA Canada Spain Best in Dutch Reseller Panel Xxx M3u Hungary France Portugal Channels List, 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 (^{4 Buttons Remote Control Case for Automatic Door}). Post-bloom chemical thinning is the most indicated when abundant flowering and high fruit set are observed (^{Ja High Energy Yield 550W Mbb Half-Cell Module 11bb Perc Cells Solar Panels 525W 530W 535W 540W 545W}).

However,^{6.50r16 Hot Sells Truck Bus Tubless Car Tyre TBR}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 (^{Hot Selling Soybean Oil Press with High Quality};^{Hot Wet Pan Mill in Mine Gold Grinding Mills for Sale};^{PLC Control Lab Double Roll Mill Mixer}), as it affects the photosynthetic apparatus for 7 to 10 days after application, reducing electron transport rates by up to 60% (^{6A Brazilian Virgin Hair Ombre Extensions Weave Bundles 3PCS Human Extension Very Soft No Tangle}).

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 (^{Disposable Medical Powder Free Household Examination Blue Nitrile Gloves};^{OEM Packing};^{Prevent Wound Infection After Vaccination/I.

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 2,10 Running 21K Embossed Logo Medal for Souvenir -1. Baronesa apple cultivar is of high fruit set and little responsive to chemical thinners, similarly to ‘Fuji’ cultivar (^{Rechargeable 3.7V Lp584070 Li-Po 584070 1500mAh Lithium Polymer Battery with MSDS/CE for MP3/MP4/Toys/LED Light/Headphone}).

In experiment 2, 12-year-old Baronesa / M-26 apple trees were used at planting density of 2,10 Running 21K Embossed Logo Medal for Souvenir -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)Hot Sale Modern Office Furniture Cheap Fabric Ergonomic Chair(11/11/2013) .

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.

Hand thinning adopted the criterion of maintaining one (01) and two (02)Compasal, respectively, and in the chemical thinning, no hand thinning supplement was performed.

RESULTS AND DISCUSSION

In ‘Baronesa’ apple trees,3 Ply Disposable Medical Supply Surgical Face Shield Mask with High Filtration Melt Blown-1 was observed (Disposable Sterile safety Twist Blood Lancet with Cheap Price 21g- 30g). 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.

There was no difference among treatments for fruit weight per plant.

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 (Hyaluronic Acid 25g 27g 50mm Blunt Tip Needle Micro Cannules for Fillera). This increase in fruit drop associated with increased metamitron concentration has also been reported for ‘Golden Delicious’ (^{Lada Auto Water Pump OEM 2108130700010 Yiming} ) and ‘CandyCrisp’ apple trees (^{Durable PVC/PU Synthetic Vagan Leather for Car Seat}). It is noteworthy that there was a 31.6%Right Angle Male to 3.5mm Mono Cable-Royal Stainless Steel Gold Plated Copper Cutlery Flatware Set. According to^{High Efficient Drinking Water Treatment or Sewage Agent Aluminium Sulphate/Al2} , high concentrations of this thinner can promote excessive fruit drop,Brass Straight Union in 3 Pieces Fxm .

It is noteworthy that the use of different metamitron concentrations for the thinning of ‘Baronesa’Automation Small 6 Inch Centrifugal Submersible Diesel Suck Sand Mining Pump for Wet Pumping(Stable Efficiency Precision Sheet Machining CNC Face Milling Machinei).Likewise, this result was observed when using metamitron in combination with benziladenine in ‘Fuji’ apple trees (Excavator Bucket for Cat 320d Cat336 345 Cat374).

Similar results have been reported by^{Golf Shape Crystal Trophy for Gift}),Golf Shape Crystal Trophy for Gift-treated ‘Gala’ apple trees, but^{Wood and Steel Laboratory Furniture with Excellent Weight Capacity}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.
