Three experiments were conducted over 2 years, with two experiments conducted on-farm in different years and one experiment conducted on-station. Treatments consisted of hand-weeding or mulches of wheat (Triticum aestivum...
Abstract We previously reported the species-specific annual ring formation characteristics of three conifers (slash pine ( Pinus elliottii ), hinoki (Japanese cypress, Chamaecyparis obtusa ) and sugi cedar, Cryptomeria japonica )) grown in same stand over 2 years. found that affected inherent difference wood density among these > sugi).
