Seedling survival and growth under contrasting light conditions were experimentally studied in combination with the effects of the drought and fire in a tropical seasonal forest. Seedlings of six tree species, Dipterocarpus alatus, D.turbinatus, Shorea siamensis, Pterocarpus macrocarpus, Xylia xylocarpa var. kerrii, and Sterculia macrophylla, were planted in a gap and under the closed canopy. For each light condition, we applied three treatments : continuous watering during the dry season (W), ground fire during the dry season (F), and no watering/no fire (intact, I). Survival and growth rate were greater in the gap than under the closed canopy for all species, most dramatically for S.siamensis and P.macrocarpus. Dipterocarpus alatus and D.turbinatus had relatively high survival under the closed canopy, and watering during the dry season resulted in significantly higher survival rate for these two species. Watering during the dry season resulted in the higher growth rate for five speci … More es. All seedlings of D.alatus and D.turbinatus, failed to resprout and died after fire. The survival rate during the dry season and after the fire treatment was higher for the seedlings grown in the canopy gap than in the shade for S.siamensis, P.macrocarpus, X.xylocarpa var.kerrii, and S.macrophylla. The seedlings of these species in the canopy gap had higher allocation to the belowground parts than those under the closed canopy, which may support ability to sprout after fire. The light conditions during the rainy season greatly affect seedling survival and resistance to fire during the subsequent dry season, and our results suggest differentiation among species in terms of seedling adaptations to shade, drought and fire.Synchronized flowering of the Gigantchloa albociliata and Cephalostacyum pergracile occurred simultaneously in 1998 and 2001, respectively. Almost all of the clumps died after the flowering, but the suppressed clumps did not flower and survived after the flowering event in case of G.albociliata, After the death of G.albociliata clumps, many clumps of Bambusa tulda emerged and stated to grow quickly. These suggest that these bamboo species can maintain sapling banks under the shade, and shaded individuals may behave differently at the flowering event. The relationship between the simultaneous death of bamboo and the regeneration process of trees and bamboos is not a simple story and need further investigation. Less

结合热带季节性森林干旱和火灾的影响，对不同光照条件下幼苗的存活和生长进行了实验研究。对翅荚龙脑香（Dipterocarpus alatus）、大果龙脑香（D.turbinatus）、大果龙脑香（Pterocarpus macrocarpus）、木荚木（Xylia xylocarpa var. kerrii和Sterculia macrophylla种植在间隙和封闭的树冠下。对于每种光照条件，我们应用了三种处理：旱季期间的连续浇水（W），旱季期间的地面火（F），以及不浇水/不生火（完整，I）。存活率和生长率均大于差距下的所有物种，最显着的S.siamensis和P. macrocarpus的封闭冠。在郁闭条件下，翅龙脑香和三角叶龙脑香的存活率较高，旱季浇水能显著提高这两种树种的存活率。在旱季浇水导致五种植物的生长率较高， ...更多信息 es.有翅杜松和陀螺杜松的所有幼苗均未能重新发芽，并在火灾后死亡。在旱季和火处理后，生长在林隙中的幼苗的存活率高于在遮荫下生长的幼苗。林冠间隙内的树种幼苗比郁闭林冠下的幼苗更容易向地下部分分配，这可能是林冠火灾后树种幼苗萌发的支撑能力。在雨季的光照条件极大地影响了幼苗的生存和随后的旱季的抗火性，我们的研究结果表明，种间分化的幼苗适应遮荫，干旱和fire. Synchronous开花的巨藻albociliata和Cephalstacyum pergracile同时发生在1998年和2001年，分别。几乎所有的丛生竹在开花后都死亡，但是在白缘竹的情况下，被抑制的丛生竹在开花事件之后没有开花并且存活。这表明，这些竹种可以维持幼树银行的阴影下，和阴影的个人可能会表现出不同的开花事件。竹子的同时死亡与树木和竹子的再生过程之间的关系不是一个简单的故事，需要进一步调查。少
