Báo cáo khoa học: "Effects of variable root damage caused by Phytophthora cinnamomi on water relations of chestnut saplings" doc

... effects of Phytophthora cinnamomi root damage on water relations of chestnut (Castanea sativa) saplings were investi- gated. The relationshipbetween root damage severity and impact on water relations ... controls. The proportion of necrotic root biomass assessed at the end of the experiment allowed us to study the rela- tionship between root damage seve...

... inserted into MPT at a concentration of 100 lm, higher con- centrations of added metals were analysed. However, the addition of these metals at concentrations of up to 1mm to the reaction mixture did ... 1 mM of the indi- cated metal ions, and unbound material was removed by gel filtra- tion. The MPT content of MPT synthase was quantified after its conversion to Form A. (B) 1 m M...

... investigate the relationship between the inhibition of root growth and changes in specific root respiration. In addition, we discussed whether the inhibi- tion of root growth ... altered root elongation. In contrast, specific respiration of roots was unaffected by the moderate salinity treatment while it was reduced by 62 % after 9 days...
