“…Under CA stress, PN was negatively correlated with the concentration, which was in accordance with Mersie and Singh (1993) and Sumbele et al (2012). Under the low and moderate concentrations of CA, PN, Ci, E, and gs in the seedlings of R. delavayi were significantly lower than that of CK; however, gs, E, WUE, and Ls showed no significant difference between the low and moderate concentrations of CA (Fig.…”

The effects of different concentrations of ferulic acid, chlorogenic acid, and protocatechuic acid were studied in a pot experiment to assess the response of Rhododendron delavayi seedlings. The results showed that three kinds of phenols promoted increases in chlorophyll (Chl) a, Chl b, total Chl, and carotenoid contents, but inhibited the accumulation of biomass. Low concentrations of ferulic acid significantly inhibited stomatal opening, the stomatal opening ratio, stomatal length and width. Chlorogenic acid and the moderate and high concentrations of ferulic acid also significantly inhibited stomatal density. Ferulic acid significantly inhibited net photosynthetic rate and stomatal conductance in seedlings, whereas chlorogenic acid significantly inhibited stomatal conductance. The low and moderate concentrations of chlorogenic acid significantly inhibited transpiration rate, and high concentrations of ferulic acid significantly inhibited the stomatal limitation value. The moderate concentration of protocatechuic acid significantly inhibited net photosynthetic rate and stomatal conductance. Ferulic acid exhibited a greater toxic effect than that of chlorogenic acid and protocatechuic acid for R. delavayi seedlings. axes of stomata; Ls -stomatal limitation value (= 1 -Ci/ Ca); PA -protocatechuic acid; PH -plant height; PN -net photosynthetic rate; RDA -redundancy analysis; SA -stomatal aperture; SD -stomatal density; SOR -stomatal opening ratio; UB -underground biomass; VAS -vertical axes of stomata; WUE -water-use efficiency (= PN/E).

“…5) is not yet known. Increased allocation of carbon to UV-absorbing compounds may have negative consequences for photosynthesis (Sumbele et al, 2012) such that reducing UV protection during times of the day when solar UV levels are low could enhance daily carbon gain. In comparison to plants that maintain high UV sunscreen protection throughout the day, plants with horizontal leaves that exhibit diurnal changes in epidermal UV transmittance will experience increased UV exposure to the underlying mesophyll both early and late in the day but not at midday (Fig.…”

“…Decline in chlorophyll contents was highly associated with production of phenolic compounds (Table 5). Recently, Sumbele et al (2012) reported with 49 plant species of Greece and Australia that photosynthetic capacity was negatively associated with leaf phenolic contents. Wheat allelochemical compounds might have inhibited chlorophyll content in canary grass seedlings either by interfering with the biosynthesis of photosynthetic pigments or by enhancing their degradation by inducing oxidative stress and generation of reactive oxygen species or both.…”

Millat-2011, AARI-2011, Lasani-2008 and Faisalabad-2008 collected at tillering (Z-30), anthesis (Z-60) and maturity (Z-90)] against canary grass (Phalaris minor Retz.). Mean emergence time of canary grass was prolonged over control by soil incorporation of residue at anthesis and maturity stages of cultivars AARI-2011 and Lasani-2008. Final emergence percentage declined by 13-31% for residue collected at different growth stages. Maximum suppression in shoot (33-51% and 28-53%) and root (34-52% and 28-54%) length and seedling dry biomass (66-88% and 58-86%) of canary grass over control was also recorded under aforementioned treatment combinations. Total chlorophyll contents in canary grass declined in response to soil incorporation of residue at anthesis and maturity stages of all wheat cultivars but an increase was recorded for residue incorporated at tillering stage. Phenolic contents in residue and residue-amended soil increased with advancement in stage of wheat growth. Biochemical bases of phytotoxicity and changes in activities of enzymatic antioxidants in canary grass seedling are discussed. Such information suggests the growth regulatory potential of residue of specific wheat cultivars against weeds of economic significance in wheat based cropping systems and scope for increasing nutrient status of soils.
