← ScienceWhich risk greatly increases following frost damage preventing grapevine bud development?
A)Increased vulnerability to opportunistic fungal infection✓
B)Decreased xylem diameter impedes water transport
C)Lowered surface tension prevents nutrient uptake
D)Inhibited root respiration leads to stunted growth
💡 Explanation
Increased risk of fungal infection occurs because cellular damage from ice crystal formation causes cell lysis, a phase change, which releases nutrients that promote fungal growth; therefore fungal infection is likely because exposed tissue provides resources, rather than impaired xylem or root respiration.
