With the stress degree stronger and the stress time longer, the protein in xylem sap changed among 14.4~31KD for all alternative split-root osmotic stress.
随着渗透胁迫强度的增加和胁迫时间的延长，木质部汁液中的可溶性蛋白质组分主要在14.4~31KD范围内变化。
Similar trend was showed with the xylem SAP ABA, but no difference was observed in xylem ABA in response to soil drying between different nitrogen treatments.
木质部aba与土壤干旱胁迫间的关系类似于根系aba的变化，但低氮与高氮处理木质部aba含量的差异没有根系aba的显著。
Roads, railways, water and gas mains, sewage pipes and electricity cables all move things around. So do the blood vessels of animals and the sap-carrying xylem and phloem of plants.
他的观点是，在某种程度上二者均由运输物质的网络构成——公路，铁路，水路以及煤气管，污水管还有电缆线都在输送物质，动物血管和植物运输汁液的木质部、韧皮部也是如此。
The results also indicated that omethoate was transported to the xylem along with SAP flows went upward and then transferred to the phloem as taking a pest-controlled effect.
检测还表明：氧化乐果由木质部随树液向上输导后再转移到韧皮部而起杀虫作用。
