Abstract

Abstract: In order to understand seedling index for screening eggplant genotypes with high nitrogen use efficiency.Solution culture was conducted to study the plant morphological traits,root morphologic characteristics and nitrogen accumulation distribution in two eggplant with different N use efficiency (NUE) under two nitrogen levels.The results showed that there were significant variations in plant height,plant dry weight,content of chlorophyll,average root length,root volume,root dry weight and total nitrogen uptake under low nitrogen stress.The 06-991 was significantly higher than 06-867 in plant height,plant dry weight,content of chlorophyll,average root length,root volume,root dry weight,total nitrogen uptake and root shoot ratio under low nitrogen stress.The traits of 06-991was respectively 1.40,1.78,1.29,1.30,1.67,2.00 times that of 06-867 under low nitrogen stress.The root shoot ratio and nitrogen distribution proportion to root from plant of 06-991 was respectively 1.18 times,1.42 times of 06-867under low nitrogen stress.The results also showed mighty prominent correlation between total N uptake and plant dry weight,root dry weight under two nitrogen levels,indicating that plant dry weight and root dry weight suitable as seedling index for screening eggplant genotypes with high nitrogen use efficiency.

Key words: Eggplant, High nitrogen use efficiency, Screen index
