The resistance and cross-resistance of scirpus juncoides *** ALS-inhibiting herbicides were tested to provide theoretical basis for effectively control scirpus juncoides *** rational use of *** identify the resistance and crossresistance of 19 populations from nine areas in Heilongjiang Province to four ALS-inhibiting herbicides by agar method and the whole-plant *** results are as the followings,the two bioassay methods had good correlation,the resistance indexes in the same area were different by two means,but resistant level was the same,similarity up to 89.5%.The resistant rates to pyrazosulfuronethyl,bensulfuron-methyl,penoxsulam and pyribenzoxim were 26.3%,36.8%,36.1%and 21.1%,*** populations evolved the highest level of resistance to pyrazosulfuron-methyl with a resistance index of ***,Tonghe,Fangzheng and Jixi populations showed cross-resistance to four ALS-inhibiting herbicides,accounting for 26.3%.The resistance of scirpus juncoides *** four ALS-inhibiting herbicides in Heilongjiang paddy field was low to moderate,five populations showed cross-resistance to four ALS-inhibiting herbicides.

A saltmarsh has developed rapidly on the mudflat of Andong Shoal,in southern Hangzhou Bay,over the last decade since *** saltmarsh vegetation changes are driven by both sediment dynamic conditions and the competition between the exotic species Spartina alterniflora(***) and the native species scirpus mariqueter(***).This study attempted to investigate large-scale spatial variations in the exotic and native species,by analyzing and interpreting a time series(2016-2018) of high-resolution(less than 1 m) remote sensing *** total area of the saltmarsh increased at a rate of 1.07 km^2/year,due to the accretion of the whole tidal *** spatial patterns revealed a new bimodal pattern for *** *** expanded over the upper to middle saltmarsh at a rate of1.68 km2/***,the *** patches at the seaward edge expanded at a negative rate of-0.005 km^2/year,indicating a different pattern in competition:*** had more advantages in the upper saltmarsh,while *** had more advantages in the pioneer zone with low ***,*** mainly established new habitats by invading *** in the middle saltmarsh,but *** occupied the bare mudflat for *** results aindicated that the interspecific competition result between *** and *** depended on elevation,and low elevation might create a favorable environment for *** to win the competition with exotic *** finding could be applied to future invasive species control and saltmarsh management.
