Jatropha Plantation (Seedling, Part 2)

Ok, in this part I will talk again about seedling but this time it is from seed. The best way to get good quality seeds is by buying it from authorized seller. The seed sold by them usually certified and tested (minimal viability is 80%). Viability means in general "capacity for survival" and is more specifically used to mean a capacity for living, developing, or germinating under favorable conditions. But if you want to get the seed from your own plant, just make sure you get the best seed. Ok, now to get the best seed you must follow the criteria described as follows:

• Seed comes from ripe/mature fruit. It is of course vital point, the ripe fruit is marked with its color that turn to yellow. As comparison, young fruit have the color of green and then turn to yellow as it ripe and turn to brown and dried.
• Seed's shape is oval with black/dark/dark brown in color.
• Other criteria are the color of the kernel, it is white brownish and you also need to consider about the crack of the shell. It must not over 10%.

ok, for better understanding, not just theory, here's the picture of the fruit in its three stage of ripening :)
