[Objective] To research the physiological response of Carthamus tinctorius L.under saline-alkali stress,so as to screen,introduce and cultivate new varieties.[Methods] With C.tinctorius seeds as the research material,saline-alkali stress treatments by different concentrations of NaCl,NaHCO_3,NaCl and NaHCO_3(1∶1) mixed solutions were carried out.The saline-alkali tolerance abilities were researched by detecting the germination percentage,germination energy,relative germination percentage,vigor index and so on.[Results]With the concentration increase of Na Cl,NaHCO_3,Na Cl and NaHCO_3(1∶1) mixed solutions,the germination percentage,germination energy,relative germination percentage,radical length and seedling fresh weight of C.tinctorius seeds gradually declined.Under Na Cl stress,the salt-tolerance concentration,median inhibitory concentration and limiting concentration of C.tinctorius seeds were 9.663‰,14.721‰ and 19.779‰,respectively.Under NaHCO_3 stress,the salt-tolerance concentration,median inhibitory concentration and limiting concentration of C.tinctorius seeds were 10.573‰,14.515‰ and 18.457‰,respectively.Under the stress of NaCl and NaHCO_3(1∶1) mixed solution,the salt-tolerance concentration,median inhibitory concentration and limiting concentration of C.tinctorius seeds were 10.239‰,14.858‰ and 19.477‰,respectively.[Conclusions] C.tinctorius had relatively strong ability of saline-alkali tolerance.
[Objective] To discover the types of plant diseases and insect pests in Chrysanthemum morifolium cv.Fubaiju in Hubei Province,and to make effective control measures for brown spot.[Methods] During the growth period of C.morifolium cv.Fubaiju,the types of plant diseases and insect pests were preliminarily investigated.Randomized block experiment on brown spot was designed to carry out comparative tests on chemical reagents and filed control.[Results]Investigation showed that there were five types of pests and diseases,which were brown spot,downy mildew,virus disease,powdery mildew and aphids.Among them,brown spot was the most serious,followed with virus disease.Results of control effect test showed that 600 times diluents of 3% polyoxin and 800 times diluents of 50% carbendazim had relatively ideal control effects.After the second drug application,control effects reached 80.88% and 79.66%; and disease indexes decreased to 9.16 and 10.23,respectively.[Conclusions] Both 600 times diluents of 3% polyoxin and 800 times diluents of 50% carbendazim could control the development and spread of brown spot,which were relatively ideal reagents.
