To clarify physiological integration for salinity stress alleviation in Zoysia matrella, interconnected clonal stolon ramets were grown in three separate pots [basal (BR), intermediate (IR), and apical ramets (AR)]. Once ramets were well established, two experimental groups were set up: stolons connected with other ramets (Intact) and stolons cut between ramets (Severed). NaCl solution was used for IR, while tap water was used for BR and AR for 49 days. For BR and AR, there was no significant difference in NaCl content in any plant part (green leaves, brown leaves, stolons, and roots) in both groups. Therefore, we concluded that no NaCl translocation in interconnected ramets occurred for both basal and apical directions. For the IR in Intact group, water content in stolons was 1.2 times higher, and NaCl content in green and brown leaves was 16 and 29% lower, respectively than in Severed group. Dry weight of both above ground and below ground parts in Intact groups were 1.3 times higher as compared to that in Severed group. It was considered that tap water treated ramets (BR or AR) translocated water to IR and decreased the amount of NaCl in the body, thereby alleviating salt stress. For the IR in both groups, NaCl content in brown leaves was 2–3 times higher than in other parts. We conclude that Zoysia matrella does not translocate toxic component, such as NaCl between ramets, and does not distribute it to other ramets; however, ramet accumulates NaCl in brown leaves under salt stress condition.

阐明生理整合以减轻盐生结缕草的盐分胁迫，相互连接的克隆stolon分株在三个单独的盆中生长[基础（BR），中间（IR）和顶端分株（AR）]。一旦确定了分株，就建立了两个实验组：与其他分株相连的茎（完整）和在分株之间切茎（切断）。NaCl溶液用于IR，而自来水用于BR和AR 49天。对于BR和AR，两组中任何植物部分（绿叶，棕叶，茎和根）的NaCl含量均无显着差异。因此，我们得出的结论是，相互连接的分株中的NaCl移位在基部和顶端方向均未发生。对于完整组的IR，茎中的水分含量比断绝组高1.2倍，绿色和棕色叶片中的NaCl含量分别低16％和29％。完整组的地上部分和地下部分的干重是切断组的1.3倍。人们认为，自来水处理的分株（BR或AR）将水转移至IR并减少了体内NaCl的含量，从而减轻了盐分胁迫。对于两组的IR，棕色叶片中的NaCl含量比其他部位高2-3倍。我们得出结论结缕草不会在分株之间转移有毒成分，例如NaCl，也不会将其分配给其他分株；但是，分株在盐胁迫条件下会在棕叶中积累NaCl。
