photoperiodism woh phenomenon hai jisme paudhe apne phool aur beej dene ka samay raat-din ki lambai se decide karte hain. Vernalisation thande temperature se hone wala process hai, jisse paudhe flowering ke liye taiyar hote hain. Aur haan, short day plants ko asal mein 'long night plants' bolna chahiye, kyunki unhe flowering ke liye lambe period of *night* (uninterrupted darkness) ki zaroorat hoti hai, bas din kam hona kaafi nahi hai.
Yeh sab main isliye pakka yaad kar raha hoon kyuki mere Papa ke khet mein moong ki fasal hai, jo short day plant hai... aur jab main board exam ke liye ratti raat jag kar padhta hoon, toh lagta hai main bhi ek tarah se 'long night plant' ho gaya hoon!
