Seed Production of Vegetable, Tuber and Spice Crops (2+1)

Botany

• Brinjal is often cross pollinated crop.
  
• Brinjal flower opens mainly in morning.
  
• Anthesis starts at 5.53 a.m. and continues upto 7.35 a.m with peak at 6.05 a.m.
  
• The dehiscences of anthers begin 30 minutes after anthesis.
  
• The stigma is receptive from 2 days before anthesis and upto 8 days.
  
• Brinjal produces 4 types of flowers with different style length. (Long style, short style, medium style and pseudo short style).
  
• For seed production and better yield, the long and medium style is desirable.
  
• To increase the production of long and medium style application of more nitrogen or spraying of growth regulators during pre- flowering and flowering stages may be followed.
