Influence of nitrogen deficiency on photosynthesis and chloroplast ultrastructure of pepper plants (Research Note)	2001	6	.pdf	application/pdf	3091	185	62	Total chlorophyll and carotenoid contents, the chlorophyll a/b ratio and the photosynthetic efficiency, indicated by the rate of CO 2 assimilation, were significantly lower in leaves of nitrogen deficient plants compared with the control (Table 1). Morphometric analysis showed that the cross sectional area of the con- trol plant chloroplasts was smaller, but the chlo- roplast length, the number of grana per chloro- plast and the number of thylakoids per granum were higher with respect to N-deficient plant chloroplasts (Table 1).The proportion of stroma matrix of the chloroplasts cross section occupied by starch inclusions and plastoglobules was in- creased in nitrogen deficient plants (Table 1).	cache/afs-5680.pdf	txt/afs-5680.txt
