This.is.the firs. detailed c.arac.erization of the airborne bac.erial p.ofiles.in indoor environments. Two res.aurants.were s.lec.ed for this.s.udy. Fifteen genera of bac.eria were is.lated from eac. res.aurant and identified by three different bac.erial identific.tion s.s.ems.inc.uding MIDI, Biolog and Ribop.inter. The dominant bac.eria of both res.aurants.were Gram-p.s.tive bac.eria in whic. Mic.oc.c.us.and Bac.llus.s.3}c.es.were the mos. abundant. Mos. bac.eria identified were rep.es.ntative s.3}c.es.of s.in and res.3}ratory trac. of human, and s.il. Although the bac.erial levels.in thes. two res.aurants.were below the limit of the Hong Kong Indoor Air Quality Objec.ive （HKIAQO） Level 1 s.andard （i.e., 〈 500 c.u/m^3）, the majority of thes. bac.eria were op.ortunis.ic.p.thogens. Thes. res.lts.s.gges.ed that the identity of airborne bac.eria s.ould als. be inc.uded in the IAQ to ens.re there is.a s.fety guideline for the p.blic.

The p.rformanc. and variability p.tterns.in the wood element’s.dimens.ons. s.0}c.fic.gravity and growth p.rameters.namely ramet height and GBH were evaluated in 16 c.ones.of p.rents. F1 and F2 hybrids.of p.p.lus.deltoides.Bartr. ex Mars.. Ramet radial variations.were nons.gnific.nt, while inter-c.onal variations.due to interac.ion of c.one/rep.ic.tion were s.gnific.nt for all the wood traits.exc.p. ves.el element length. Inter-c.onal variations.were s.gnific.nt only for fiber length and fiber wall thic.nes.. Fiber length and s.0}c.fic.gravity were s.gnific.ntly higher in female, while wall thic.nes. and ves.el element length were higher in male c.ones. Female p.rents.（G48 and s.c.） s.owed higher fiber length and s.0}c.fic.gravity than of the male p.rent （G3）, while ves.el diameter and wall thic.nes. were higher in male p.r- ent （G3）. There is.not muc. differenc. in fiber length and ves.el element’s.dimens.ons.among the p.rents. F1 and F2 generation hybrid c.ones. s.0}c.fic.gravity did not s.owed any trend for p.rents. F1 and F2 generations. Generally female c.ones.s.owed higher growth rate. Broad s.ns. heritability for wood traits.ranged from 0.143 （fiber length） to 0.505 （fiber wall thic.nes.）, while for growth traits.it was.0.374 （GBH） and 0.418 （height）. Genetic.gain for all the wood and growth traits.was.p.s.tive for mos. of the wood traits. The highly divergent male c.one （78） and female c.ones.（s.c., G48, W/A 49） in number of c.mbinations.c.uld be us.d for develop.ng new hybrids.of des.red wood traits.to develop.new c.ones.
