Thirty lavender varieties in five sections were investigated in leaf characters and fragrance. Sections Lavandula and Pterostoechas possessed the highest (7.23) and the lowest (2.01) value of the length/width, respectively. Because sections Lavandula (3.59cm) and Stoechas (3.00cm) possessed the approximate value of the leaf length and leaf width, lavender varieties couldn't be identified only by the leaf character.

During the early growth stage of seedlings, basal stem diameter and paripinnate number were decreased with the increasing of shade, taproot length, root : shoot ratio, total dry weight and leaf area per seedling were maximal under 37.3% NS, specific leaf area was increased with the increasing of shade, but the relative growth rate was declined. Seedlings grew fastest under 0.6% NS, suggesting that nutrients stored in seeds played an important role at the early growth stage. The treatment of 37.3% NS was best for established seedlings in seedling height, basal stem diameter, paripinnate number, rachis length, the maximum sub-leaflet number of individual paripinnate, leaf area per seedling, relative growth rate and net assimilation rate. Light intensity was positively correlated to total dry weight, and negatively to specific leaf area. The maximum of SLA was observed under 15.5% NS.

The leaf area, single leaf fresh weight, flavone content and lactone content in good variety were 2.04, 2.71, 2.05 and 2.17 times of those in common variety respectively. There were no obvious difference between the female and staminiferous plants in leaf output character, flavone content and lactone content, which proved that there were hereditary change among the gingko variety in leaf output character, flavone content and lactune content.

The results showed that:(1) low N stress significantly decreased the leaf SPAD value, leaf nitrogen content, nitrate reductase activity and reduced distance between leaf-umbrella, leaf area. And these impact aggrandized as the stress intensity increased.(2) Responses to low-N stress were in different degrees between different varieties of rubber tree seedlings. On the whole, GT1 was most sensitive to stress, PR107 next, and RRIM600 was the least sensitive.(3) The SPAD value, DBL, LA were significantly positive correlated with LNC, NRA in the seedling leaves.
