Objective: Evaluate the effect of three types substrate and different shoot lengths onthe rooting Carica papaya L. shoots.Design/ methodology/ approach: This experiment followed a completely randomizeddesign with 2×3 factorial arrangement. Shoots 30 40 cm length werecollected in March 2018 from lateral branches plants (Carica L.)native to various regions Guerrero. were placed substrates: 1)sand...
selection cutting using skidding system often causes physical damage to residual stand through felling and skidding resulting decline of bole quality and tree value. this research evaluated logging damage using skidding system on residual trees and stand regeneration in uneven aged hardwood forest of asalem, were selection cutting was practiced. in this regard, systematic sampling method was us...
breeding based on selection indices is an effective method for improving complex traits such as yield. to assess the efficiency of different selection methods, 50 genotypes of tall fescue (festuca arundinace) were evaluated under two moisture conditions including full irrigation (normal environment) and deficit irrigation (stress environment). the experiment was conducted according to a randomi...
Logistic regression equations of prescribed fire mortality were developed for white fir (Abies concolor [Gord. and Glend.] Lindl.), sugar pine (Pinus lambertiana Dougl.), ponderosa pine (Pinus ponderosa Laws.), incense-cedar (Calocedrus decurrens [Torr.] Floren.), and giant sequoia (Sequoiadendron giganteum [Lindley] Buchholz) in the southern Sierra Nevada, California. A total of 1025 trees wer...
In this paper, 3-D laser scanning imaging system was introduced to forestry measurement for data collection. Then the paper discussed the method for stand volume measure and crown measure by the new equipment. There are three methods to measure the stand volumes: using cylindricals and truncated cones to model the tree stem, collecting the point clouds of the tree stem to produce the surface of...
Forest resource inventories must include wood quality information to support the optimum use of wood fibre. The objective of this study was to develop models relating maximum live branch diameter (MBD), which affects lumber value, to tree and stand characteristics that can be measured through current and emerging remote sensing technologies. Using non-linear mixed effects models for six Canadia...
Trisomy G (Down's syndrome or "mongolism") is associated with multiple dental abnormalities (J. OSTER, Mongolism, Copenhagen: Danish Science Press, 1953). Teeth are frequently missing, all morphologic classes are involved, and the remaining teeth are characterized by size reduction (M. M. COHEN and A. WINER, I Dent Res 44:197-208, 1965; and M. M. COHEN, S. M. GARN, and M. A. GECIAUSKAS, J Dent ...

Abstract. Bareke T, Addi A. 2021. Allometric equation for aboveground biomass estimation of Galiniera saxifraga (Hochst.) Bridson in Gesha-Sayilem forest, southwestern Ethiopia. Asian J For 5: 76-82. There is limited information about the precise quantification Aboveground Biomass (AGB) species-specific allometric equations shrubs and small trees. Thirty plants were selected to develop equation...
