studies on roots biomass of hippophae rhamnoides community in high altitude sand in guinan of qinghai 青海貴南高海拔沙地沙棘種群根系生物量的研究
the estimate of fine root biomass in upper soil layer of larix olgensis plantation by geostatistics method 采用地統(tǒng)計學方法對落葉松人工純林表層細根生物量的估計
the leaves biomass, root biomass, total biomass, sla, lar, srl, rlr and rgr of three species had very obvious plasticity to soil water . but the plasticity degree of three plants to different soil water were c . smyrnioides > a . sylvestris > c . violaceum 三物種的葉生物量、根生物量、總生物量、sla、lar、srl、rlr和rgr對土壤水分的可塑性均較大,但可塑性程度為明黨參峨?yún)⒋鲄ⅰ?i class="labawb" onClick="playMp3('sound_c_3')">
ginnala's leaf becomes thicker and its leaf area of a plant decrease . the specific leaf area under drought conditions is : a . ginnala > p . davidiana > m . baccata > p . ussuriensis . ( 5 ) un der drought conditions, all of the four species have the abilities to adapting drought environment by increasing root biomass 茶條槭在干旱脅迫下比葉面積最高,山桃、山荊子次之,山梨最低;(5)在水分脅迫下,四樹種均能通過顯著增加根量分配來適應干旱。
2 . all the corresponding parameters of a . sylvestris were similar with c . smyrnioides in procreate period in april . but the parameters of root length, diameter of root, volume of root, leaf biomass, root biomass, total biomass, root mass ratio ( rmr ) and sla had the maximal value in moderate treatment in vegetative period in january 峨?yún)⒌南鄳L參數(shù)在4月生殖生長期與明黨參隨土壤水分的變化趨勢相似;但在1月份的營養(yǎng)生長期,根長、根粗、根體積、葉生物量、根生物量、總生物量、rmr和sla均以中度水分條件最大。
