Effects of nitrogen deficiency on the gas exchange,chlorophyll fluorescence and chloroplast ultrastructure in fingered citron

Recovery effect of tomato leaves photosynthesis and chloroplast ultrastructure after a short-term low nocturnal temperature

With nocturnal low temperature treatments for 12 h each day,the chloroplast ultrastructures were observed and net photosynthetic rate(Pn),stomata conductance(Gs),intercellular CO2 concentration(Ci),stomata limitation(Ls),transpiration rate(Tr) and water use efficiency(WUE) of Eucalyptus urophylla and E.

Mo deficiency affected the chlorophyll content and ultrastructure of chloroplast of winter wheat cultivars.

grown at two different altitudes (3@P1200 m, 3@P2980 m) were measured and the ultrastructure of chloroplasts were observed for studying the photosynthetic adaptability of plants to the influences of stress conditions in alpine environment.

After 5 days under low temperature, the ultrastructure of chloroplast was disintegreted evidently in control,but did not in treatments.

Effects of potassium level on photosynthetic characteristics and chloroplast submicroscopic structure of muskmelon leaves.;

A study on chlorophyll content and chloroplast structure of normal and chlorophyll-deficient mutant plants of Kandelia candel;

In order to investigate virulence of the 2b protein on Nicotiana glutinosa plants,in terms of chloroplast structure and photosynthesis,a mutant Fny-CMVΔ2bpro,which cannot express the 2b protein,was achieved by introducing mutant sites in the 2b gene of Fny-CMV.

Fairfax)was used to study the effects of darkness on seedling quality in the as-pects of morphological indexes,chloroplast ultrastructure and chlorophyll fluorescence parameters.
