Abstract
Sweet cherry is a common economic fruit tree in China.The occasional and temporal drought,which is common in South China areas,has become a main environmental factor that decreases vegetative growth and yield,and reduces fruit size,and sometimes quality,causing important economic losses in orchards.Grafting elite and commercial cultivars onto rootstocks capable of reducing the effect of drought stress on shoot is a promising tool for enhancing drought resistance.It was reported that certain traits of rootstocks had a marked influence on drought-stress response,including differences in root distribution,water uptake efficiency and root hydraulic conductivity,as well as crop load and fruit characteristics.However,little information was available about the rootstock germplasm screening for drought tolerance in sweet cherry.The objective of the present study was to screen the potential cherry rootstock germplasm to make sweet cherry adapt to the drought stress.The sweet cherry ‘ Zaodaguo ’(Prunus avium L.) were grated on four rootstocks,Prunus avium ‘ Zaodaguo ’,P.pseudocerasus ‘ Daqingye ’,Cerasus sachalinensis ‘ Benxishanying ’ P.avium × P.pseudocerasus ‘ Colt ’ and P.pseudocerasus ‘ Laiyangaiying ’.After an initial period of growth under well-irrigated conditions the amount of irrigation was gradually reduced to 40% of field moisture capacity as the drought stress,to simulate natural drying in the soil.Then,the responses of photosynthesis and chloroplast ultrastructure alternations of ‘ Zaodaguo ’ sweet cherry to drought stress were analyzed.The results showed that the leaf relative water content(RWC),total chlorophyll contents(TChl),photosynthetic rate(Pn),stomatal conductance(Gs),and maximum quantum yield of PSⅡ(Fv / Fm) of all seedlings grafted on four rootstocks were significantly altered by the drought stress(P 0.05).With aggravated drought stress,the Pn,Gs,Tr(transpiration rate) and Fv / Fm decreased gradually.After subjected to drought stress for 16d,the decreases with 10.7%,28.4%,37.8%,51.5%and 20.5% were observed in RWC,TChl,Pn,Gs and Fv / Fm of ‘ Benxishanying ’.Correspondingly,the decreases were generally above 2-fold higher in other three rootstocks than the decreases in ‘ Benxishanying ’,and the greatest decrease generally occurred in seedlings grafted on ‘ Colt ’.Under drought stress,the chloroplast lamellar structures were disordered in the leaves of ‘ Laiyangaiying ’,‘ Daqingye ’ and ‘ Colt ’,in which the chloroplast was swollen and the fine structure was deformed,and the chloroplast matrix zone expanded and the lamellae structure became loose;however,the chloroplast ultrastructures were relatively intact in leaves of ‘ Benxishanying ’.Through membership function analysis based on the 10photosynthetic parameters,the drought resistance capacity of the four cherry rootstocks was in descending order as follows :‘ Benxishanying ’,‘ Laiyangaiying ’,‘ Daqingye ’ and ‘ Colt ’.These results above indicate that ‘ Benxishanying ’,as a relatively drought tolerant rootstock,is a promising choice for sweet cherry cultivated in arid and semi-arid areas.
