Rhizomes Help the Forage Grass Leymus chinensis to Adapt to the Salt and Alkali Stresses

Figure 1

General morphology of Leymus chinensis. Abbreviations: A11, horizontal apical rhizome bud; A12, vertical apical rhizome bud; A2, daughter apical rhizome shoot; B1, axillary rhizome bud; B2, daughter axillary rhizome shoot; C1, shoot bud; C2, daughter axillary shoot; FS, parent flowering shoot; VS, parent vegetative shoot; YR, young rhizome [25]. Here we considered A11, A12, A2, B1, and B2 as the daughter shoots from rhizomes (DSR), C1 and C2 as the daughter shoots from tillers (DST); all these young shoots are included in the total number of daughter shoots (TDN), and YR as rhizome number (RN).
