摘      要:We employed capacitance to evaluate the kinship and interspecific variation of homoploid hybrid conifer Pinus densata,***,*** and artificial hybrids of ***(maternal parent)and ***(paternal parent)which were cultivated and selected in the common garden *** measuring capacitance spectra under different voltage frequencies,we could differentiate different germplasms based on the electrical *** aims to demonstrate that *** as the hybrid of *** and *** based on the capacitance values of the species,and to provide new evidence to the previously known biological evidence,as well as and the parental effect on the *** results revealed that capacitance values between the species are significantly different in the spectra where *** positioned at the lowest and *** was much higher than all other species,indicating that *** had possessed a great capacity to store electrical *** capacitance spectra of *** and the artificial hybrid are not similar,which rejected our *** of the capacitance values of *** and the hybrids were closer to *** than to ***,which shows that the maternal influence was stronger than the paternal *** analysis on the relationship between capacitance and fitnessrelated characteristics showed that capacitance is negatively correlated to mortality rate,and positively correlated with second-year survival *** capacitance values of *** and some of the hybrids reveal their superior adaptability to harsh environment in the Tibet *** concluded that capacitance as a new indicator for plant fitness and evolution evidence of homoploid hybrid conifers.
