Figure 4. The effect of salinity on tillering of Spartina alterniflora grown under greenhouse condition. (a) percentage of tillering; (b) number of tiller per seedling; (c) plant height. The solid square represents seedlings treated with 0‰ salinity, the open circle represents seedlings treated with 15‰ salinity, the solid triangle represents seedlings treated with 30‰ salinity.
Table 1. The content of strigolactones and its derivatives under different salinity treatments in Spartina alterniflora roots. ND means 5-DS or strigol was not detected.
