Complete intra-annual cycle of leaf area index in a Platanus orientalis L. stand

摘要: Leaf area index (LAI) analysis of deciduous forest trees is usually restricted to seasonal monitoring involving the assessment distinct leaf phenological stages within definite time intervals year. However, continuous LAI that includes entire periods necessary define ecophysiological characteristics trees. Therefore, this study investigated intra-annual cycle for a Platanus orientalis L. stand in Bartin watershed Turkey. A complete involves three periods: foliation, stable, and defoliation. The foliation period comprises budburst, emergence flushing sessions, whereas defoliation consists senescence fall sessions. stable between these two when values are at climax around maximum. Eight points were determined field by hemispherical photography technique. Over relatively frequent schedule, photographs taken almost weekly durin...
