Bibliometrics and research progress in the relationship between seed dispersal and dormancy
摘要
Abstract
In plant life history,seed dispersal and seed dormancy are survival strategies to improve seed germina-tion rate,which can avoid the risks from seed germination to seedling establishment in time and space.The relation-ship between seed dispersal and dormancy is crucial for understanding plant adaption to environmental stresses.In this study,1017 articles published from 1999 to 2022 were retrieved from the Web of Science Core Collection on the topic of"seed dispersal"or"seed dormancy".The literature data were extracted by using the bibliometrix package of the bibliometric tool CiteSpace 6.2.R1 and R software.The statistic information was visualized for annual number of publications,countries of published articles,authors,and keywords.Based on literature review,we found that:(1)There was a significant negative correlation between seed dispersal and seed dormancy,and the degree of significance varied with environmental changes and tissue level;(2)In adapting to the extreme environ-ment,some desert plants have evolved two or more forms of seeds,corresponding to different combinations of dis-persal capacity and dormancy level,so as to improve the survival rate of seeds after dispersal and to expand popula-tion range;(3)Dormancy keeps seeds alive during the dispersal process,so the trade-off between the optimal dis-persal distance and the dormancy level is one of the main issues about species regeneration strategies;(4)The dor-mancy and dispersal characteristics of seeds coevolved with other life history strategies,and the relationship between seed dispersal and dormancy is affected by environmental temperature,rainfall,number and size of seeds.The evo-lutionary goal of seed dormancy and dispersal strategies is to help species cope with the unpredictability of their liv-ing environment,improve fitness,and maintain the ability of species to regenerate and reproduce.Understanding the relationship between plant seed dormancy and dispersal depends on the joint exploration of plant life history strategies.关键词
