Physiological disorder 'Blanking' in garden pea (Pisum sativum):

• Reduced ovule development occurs generally under poor nutrition.
• Complete ovule absence is genetic or developmental sterility.
• Merger of nearby ovules leading to seed absence: Under high temperature, drought, or moisture stress during flowering and early embryogenesis, adjacent ovules fail to separate and fuse/merge into aborted vestigial tissue, resulting in conspicuous empty seed spaces (blank spots) along the pod.
• Absence of parchment layer produces edible-podded sugar snap/snow peas.
  
  Option breakdown:
• Not the specific definition.
• Incorrect mechanism.
• Merger of nearby ovules leading to seed absence is the exact characterization.
• Describes snow pea morphology, not blanking.
