Effect of seed hydro-priming durations on germination and seedling growth of bitter gourd (Momordica charantia).

The yield and quality of an annual crop are highly dependent on uniform and rapid germination of the seeds. In case of bitter gourd (Momordica charantia), the germination and field emergence is always a problem as seeds have thick and hard seed coat. Pre-sowing hydro-priming is one of the most suita...
