SEASONAL GROWTH AND GROWTH RATE‐COLONY SIZE RELATIONSHIPS IN SIX SPECIES OF SAXICOLOUS LICHENS

摘要: The pattern of seasonal growth and the relation rate to colony size were studied in four foliose two crustose species saxicolous lichens. A new method measuring was used whereby advance a sample lobes along millimetres marked on substrate measured under magnification x10. Three peaks found(in March, June November) for single peak (in May August) species. THe corresponded approximately rainfall. Growth increasing fell smooth exponential curve when expressed cm squared/ unit time basis. result is consistent with linear radial most thallus sizes six There also evidence an incresae initially until about 1.5 diameter sepcies achieved.
