Treatment

 

- 60 ml ACF-SR per tree per dose

- 2.27 grams of EcoBac per tree per dose

 

Kg Cherries per Tree

 

The treated Red Lantern trees had a total yield of 24.6 Kg per tree compared to the

control value of 21.0 Kg per tree, with an improvement of 17% per tree

The treated Early Van trees had a total yield of 31.5 Kg per tree compared to the

control value of 29.8 Kg per tree, with an improvement of 6% per tree.

 

Single Cherry Weight

 

The average cherry weight in the treated Red Lantern trees was 10.43 grams

compared to the control value of 9.89, with an improvement of 5% per cherry.

The average cherry weight in the treated Early Van trees 8.39 grams compared to the

control value of 7.86, with an improvement of 7% per cherry.

 

Soluble Solids Content and Titratable Acidity

 

Soluble solids content (%) was determined by Milwaukee MR 200 hand digital

refractometer (ATC, Rocky Mount, USA) at 20°C (°Brix). Titratable acidity (TA), as

malic acid (%), was determined by titration to pH 8.1 with N/10 NaOH. On the basis

of the measured data, soluble solids/titratable acidity ratio (Solid to acid ratio or

ripening index—RI) was calculated.

The values for Soluble Solids Content (Brix) and Titratable Acidity, for treated and

control, and for both types of trees, is presented in Table 2 (next page). In both

types of trees, the Brix was greater for the treated cherries.

The accepted measure of ripeness (Ripeness Index) is the ratio of Soluble Solids

Content / Titratable Acidity. For the Red Lantern trees, the test Ripeness Index (RI)

was 52.1 compared to the control of 45.4, or 15% improved. For the Early Van

trees, the treated RI was 44.7 compared to 32.8 RI for the control, or 36% improved.

 

Conclusion

 

The yield of cherries improved from 6% (Early Van) to 17% (Red Lantern) relative to

the control trees. On average, for both types of trees, the average size of each cherry

increased 5% to 7%.

More importantly, the Ripeness Index improved by 15% (Red Lantern trees) to 36%

(Early Van trees).

This study proved the efficacy of ACF-SR dosing to two species of cherry trees.
