Rain covers are widely used to protect cherries from the elements, but they can also influence fruit characteristics, including color. Understanding how rain covers affect cherry color, especially in different varieties, is crucial for growers seeking to maintain high-quality fruit.
This article will explore the differences in how rain covers impact cherry color and offer solutions to minimize negative effects.
Why Does the Skin Color Become Lighter?
UV-B radiation plays a significant role in the synthesis of anthocyanins, which are responsible for the color of cherry skins.
A reduction in UV-B radiation caused by rain covers leads to decreased anthocyanin production, resulting in lighter fruit color.
How Do Rain Covers Affect the Color of Different Cherry Varieties?
Rain covers affect cherry color differently depending on the variety. For bi-colored varieties like ‘Rainier,’ which have anthocyanins concentrated in the skin, the reduction in UV-B radiation leads to lighter skin color.
In contrast, for red varieties like ‘Bing’ and ‘Sweetheart,’ where anthocyanins are present in both the skin and flesh, the impact on color is minimal.
The variation in anthocyanin distribution explains these differences in color response.
Impact on Bi-colored Varieties
Studies show that rain covers have a significant negative impact on the color of bi-colored varieties like ‘Rainier.’ These cherries have yellow flesh and red skin.
When rain covers are used, the red coverage on ‘Rainier’ cherries decreases substantially, from 71% in the control group to 42% under rain cover treatment.
Impact on Red Varieties
For varieties like ‘Bing’ and ‘Sweetheart,’ where both the flesh and skin are red, rain covers have minimal effect on fruit color.
These varieties retain their color despite reduced UV-B exposure.
So, What Can Be Done to Address This Issue?
This is a key area of our research, and after extensive studies and trials, we found the following solution.
Solution: Minimizing the Negative Impact on Cherry Color
The Anti-dripping Cherry Cover Film is a highly effective solution. With a sunlight transmittance rate of up to 90%, this material ensures optimal light penetration while significantly reducing the negative effects that PE tarpaulins have on cherry growth.
Not only does it effectively prevent fruit cracking, but it also helps to maintain the natural color of cherries.
Conclusion
In conclusion, rain covers can significantly affect cherry color, with different impacts depending on the variety. Bi-colored varieties like ‘Rainier’ are more affected by the reduction in UV-B radiation, while red varieties like ‘Bing’ and ‘Sweetheart’ are less influenced.
By using advanced solutions like the Anti-dripping Cherry Cover Film, growers can protect cherry quality, maintain optimal fruit color, and reduce the negative effects of rain covers on growth.
