Powdery mildew, caused by Podosphaera aphanis, appears as white powdery patches on strawberry leaves and fruit. It thrives in warm, humid conditions and can reduce yield and quality. Fungicidal sprays and good air circulation help manage it. .
Strawberry plants are classified into how many day-length flowering categories?
Four
Three
One
Two
Based on day length, strawberries are grouped into three categories: June-bearing (short-day), everbearing (long-day), and day-neutral. Each type flowers and fruits under different photoperiod conditions. Growers select types based on harvest timing and climate. .
Which plant hormone plays a major role in strawberry fruit ripening?
Auxin
Abscisic acid
Ethylene
Gibberellin
Abscisic acid is the key hormone regulating non-climacteric fruit ripening in strawberries. Its levels increase during ripening and influence sugar accumulation and color change. Auxin and gibberellin have roles earlier in fruit development. .
What is the scientific name of the wild strawberry commonly found in forests?
Fragaria chiloensis
Fragaria vesca
Fragaria × ananassa
Fragaria virginiana
Fragaria vesca, also called woodland or wild strawberry, grows in temperate forests and meadows. It produces small, intensely flavored berries and is diploid, unlike the cultivated octoploid species. It has been used in breeding programs. .
