Correct Answer

(A) Sucrose

Explanation

Solution: A commonly used carbon energy source in plant tissue culture media is Sucrose .

In other words, the amount of seed required to raise a crop successfully on a given land is called a seed rate for that crop of the land. The seed rate of cucumber is 4 - 5 kg/ ha. The seed rate of bottle gourd is 6 - 8 kg/ ha. The seed rate of bitter gourd is 4 - 6 kg/ha. The seed rate of sponge gourd is 3 - 4 kg/ha. It is not 8 - 10 kg/ha. Thus it is not correctly paired.
