Biology of Euphorbia prunifolia jacq. seeds

Euphorbia prunifolia Jacq. has a very short life cycle of 3 months and each plant is capable of producing an average of 720 seeds. An estimated 720.7 million seeds can be produced from a hectare in a season. From soil samples, 30 million seeds are found in the top 10 cm of soil. Seeds remain viable...
