摘要
There are four reproductive and regenerative countermeasures of the main woody species in MaoLan Karst Forest.(1)The seed has shorter life span.The ripe seeds germinate rapidly to form seedling when it has fallen into the soil. The seedlings grow slowly to wait till the gap emerges.The seedlings grow rapidly and join in the present population as soon as the gap emerges.(2)The seed has shorter life span.The ripe seeds germinate rapidly to form seedling when it has fallen into the soil.If there are gaps in the forest the seedling grow rapidly and join in the present population,the seedlings will die speedly.(3)The seed has shorter life span.If there are gaps in the forest,the ripe seeds germinate when it has fallen into the soil and grow rapidly to join in the present population,otherwise,the seeds will lose their germination ability.(4)The seed has longer life span.If there are gaps in the forest,the ripe seeds germinate when it has fallen into the soil and grow rapidly to join in the present population,otherwise, the seeds in the soil will wait till the gap emerges.The main woody species of MaoLan Karst Forest adopt one of the four countermeasures,or both at the same time.
