查尔斯·达尔文(Charles Darwin，1862,1877)在任何协议或法律保护兰花物种或个体种群之前，对兰花授粉机制进行了田间和实验室研究。有关稀有和受威胁兰花生殖生态的信息仍然是其保护的固有信息，因为在人类世期间，兰花的数量继续减少。我们提供了代表五个属的种的案例研究(Galant&R.Br.，Corunastylis Fitzg.，evripedium L.，Spiranths Rich.和Thelymitra j.R.Forst)。&G.Forst.)在三个国家(美国、澳大利亚和中国)。我们比较了它们授粉系统的差异和生育率的季节变化。座果率和/或种子发育率的下降与繁殖系统、传粉者生活史/觅食行为和气候周期进行了比较。我们的结论是，虽然一些兰花物种是传粉者有限的，但几个相互关联的因素影响着陆生/石生兰花的繁殖率。
Charles Darwin (1862, 1877) conducted field and lab research on orchid pollination mechanisms before any protocols or laws protected orchid species or individual populations. Information on the reproductive ecology of rare and threatened orchids remains intrinsic to their conservation as populations continue to diminish during the Anthropocene. We provide case studies of species representing five genera (Galant& R. Br., Corunastylis Fitzg., evripedium L., Spiranthes Rich., and Thelymitra j. R. Forst. & G. Forst.) in three countries (the United States, Australia, and China). We compare differences in their pollination systems and seasonal variations in their fertility rates. Declining rates of fruit set and/or seed development are compared to breeding systems, pollinator life histories/foraging behaviors, and climate cycles. We conclude that, while some orchid species are pollinator limited, several interrelated factors influence rates of fecundity in terrestrial/lithophytic orchids.
