| Abstract: | The wood structures of five wind - resistant clones,PR107,Haiken1,GT1,PB86and RRIM600 of Hevea brasiliensis Muell Arg. were studied by means of light microscopyand scanning electron microscopy. The wind -resistance was compared among the 5 clonesbased on 13 xy1em anatomical elements,e. g. amount and distribution of gelatinous fibres,vessel member length,percentage of multip1e pore -vesse1s,vessel density,ray frequency,height of uniseriate,height of multiseriate,width of multiseriate,percentage of mu1tiseriate,and length and width of fibres. The relationship between the wood anatomical characteristics and wind -resistance of the c1ones were observed. Resu1ts disc1osed distinct differencein some xylem compositions among the five clones. The even distribution and largerquantity of gelatinous fibre increased wood toughness and,as a resulte,improved wind resistance of the trees. The fibre length was found positively correlated with wind resistanceand the vessel density negatively with wind resistance. |
