There has been some transition to using low-input fine fescues on golf courses, but these species have poor traffic tolerance and divot recovery, making them impractical for playable areas courses. The objectives of this study were determine the effect plant growth regulator (PGR) trinexapac-ethyl performance fescue mixtures when managed as a course fairway identify that perform well under stre...
این آزمایش برای بررسی اثر ترکیبات آللوپاتیک اکالیپتوس ((Eucalyptus camaldulensis بر جوانهزنی بذر و رشد گیاهچههای Festuca arundinaceaدر شرایط آزمایشگاهی انجام گرفت تا میزان تأثیر ترکیبات آللوپاتیک و همچنین تأثیر پیش‌تیمار با جیبرلیک اسید و سالیسیلیک اسید بر کنترل خسارت ترکیبات آللوپاتیک تعیین شود. محرکهای شیمیایی استفاده‌شده عبارت بودند از: سه سطح جیبرلیک اسید و سه سطح سالیسیلیک اسید و 5 غلظت...
Resistance to the invasion of exotic plants may sometimes result from the strong effects of a relatively small number of resident species. Understanding the mechanisms by which such species resist invasion could provide important insights for the management of invaded ecosystems. Furthermore, the individualistic responses of community members to resource availability and environmental gradients...
