Two 14-day-old seedlings of maize (Zea mays L.) cultivars (3223 and Vero) were exposed to different concentrations of lead [0, 2, 5 and 8 mM Pb(NO 3 ) 2 Á4H 2 O] for 8 days. Exposure of maize cultivars to excess Pb resulted in a significant root growth inhibition though shoot growth and absolute water content remained less affected. The results of chlorophyll a fluorescence indicated that the highly toxic Pb level affected photochemical efficiency in 3223, while no significant effect was observed in the Vero. At the highly toxic Pb concentration, higher membrane leakage was observed in 3223 leaves than that of Vero. This result was related to the accumulation of Pb. On the other hand, the results suggested that there were similar responses in total soluble POD and GR activities with increasing Pb concentrations between both cultivars. But APX activity significantly decreased at highly toxic Pb level in the Vero while a significant increase observed in the 3223. However, SOD activity in 3223 significantly decreased at the highly toxic Pb concentration compared with that at 2 mM Pb concentration. The results of the present study indicated that, Vero withstands excess Pb with its higher Pb accumulation capacity in roots and better upregulated protective mechanisms compared to 3223. Therefore, Vero is more tolerant to Pb toxicity compared to 3223 which was found to be a less tolerant cultivar.

“…Some herbicides can also affect the growth and development of crops by impairing normal physiological parameters or functions. For example, flumioxazin can cause a sharp drop in P N and g s in grapes (Bigot et al 2007). Leaf SPAD values are a direct reflection of the relative leaf Chl and are positively correlated to Chl content.…”

The effects of various concentrations of bensulfuron-methyl residues (BSM, 0-500 µg kg -1 ) on the growth and photosynthesis of soybean and peanut were studied. Shoot length, root length, root-to-shoot ratio, and biomass of soybean and peanut seedlings declined with the increase of BSM residue concentrations. As the concentration of BSM increased, SPAD value, net photosynthetic rate, stomatal limitation, stomatal conductance, and transpiration rate also declined with varying extent, but dark respiration rate and intercellular CO 2 concentration increased gradually. PSII maximum quantum yield, actual quantum yield, and electron transport rate were significantly reduced by the BSM residues in soil, and the reduction was mostly attributed to the decrease in photochemical quenching coefficient. The results showed that photosynthesis in both crops was limited by nonstomatal factors. The residues of BSM caused reversible damage in PSII reaction centers and decrease the proportion of available excitation energy used for photochemistry.Additional key words: Arachis hypogaea; chlorophyll fluorescence; gas exchange; Glycine max (Linn.)

“…Some are invasive and need sampling like spectrophotometric estimation of chlorophyll a concentration (Prieto et al, 2004), cell size measurement (Eggert et al, 2006), gas-exchanges (Bigot et al, 2007), epifluorescence (Tretiach et al, 2010) while others, such as surface colourimetry and chlorophyll a fluorescence measurement, are not destructive and are extremely useful in the field.…”
