Of the above parameters, leaf abscission was the most affected by salinity, with the concentrations of 40 and 60 mM NaCl resulting in an increase of approximately 100% in the number of abscised leaves when compared to the control.
lanatus exhibit a form of serotiny (canopy seed storage) in that the cones do not disintegrate, but gradually dry out, retaining the partially exposed abscised seeds within the desiccated cone (Grobbelaar, 1989, 2004).
Recently abscised buckthorn leaves have a relatively low C:N ratio (e.g., 19.6 - 20.6 for leaf litter collected in WI; Miller, 2010), largely due to high concentrations of nitrogen in the leaves (Knight et al., 2007; Heneghan et al., 2002, 2006).
Dimensions: Abscised part of clitellate lectotype >70 mm long, 10 mm wide at 10, 14 mm in region of tubercula pubertatis.
"The levels of heavy metals in abscised leaves are also raised, and they are clearly there to be excreted rather than stored," The Telegraph quoted Ford as saying.
Nay and Perring (2005) studied Ectomyelois ceratoniae (Zeller) (Lepidoptera: Pyralidae) larval mortality due to ant predation and heat load from abscised dates remaining on the tree and dates fallen to the ground.
This symptom makes it difficult to use old (>1 year old) foliage in carbon distribution studies, unless the amount of foliar biomass abscised has been measured.
After the indicated interval of time the explants were temporarily removed from the chamber and petioles that fell off with a gentle touch were recorded as abscised. To check for ethylene-induced chlorosis in healthy recently expanded trifoliate leaves, excised leaves were placed on moist paper towels in a dark chamber at 23[degrees]C, the air was brought to 10 [micro]L [L.sup.-1] ethylene by injection with a known amount of pure ethylene, and leaves were then visually checked for signs of chlorosis at the indicated number of days after start of the ethylene treatment.
During the present study, these two forms occur notably as abscised pinnules, very rarely as ultimate pinnae of which three were collected.
