Role of Immigration and Other Processes in Determining Epiphytic Bacterial Populations

摘要: Conceptually, there are 4 major processes that can influence the size and composition of bacterial populations on leaves. Bacterial population sizes a leaf increase by both multiplication as well immigration bacteria from other In contrast, death cells their migration contribute to decreases in size. It appears most workers have assumed growth predominant determine sizes. These obviously much more easy study than emigration since they be done isolation laboratory or greenhouse. For example, plants easily studied inoculating isolated incubation chambers; increases directly attributable bacteria. studies importance require source immigrant conditions facilitating maintained. Since which favour not yet understood, such must under field conditions. They therefore face complications variable environmental make experiments difficult reproduce. this reason, information relevant understanding occur inferences made simple observations. Most observations been sufficiently detailed partition many factors epiphytic populations. To date, few designed understand
