Merlot. Leaf water potentials (epsilon(L)) for Merlot grafted onto the 1103P root system (-0.91 +/- 0.02 MPa) were +0.15 MPa higher than Merlot on 101-14Mgt (-1.06 +/- 0.03 MPa) during spring, but dropped by approximately -0.4 MPa from spring to autumn, and were significantly lower by -0.15 MPa (-1.43 +/- 0.02 MPa) than
for Merlot on 101-14Mgt (at -1.28 +/- 0.02 MPa). Surprisingly, g(s) of Merlot on the drought-tolerant root system (1103P) was less down-regulated and canopies maintained evaporative fluxes ranging from 35-20 mmol vine(-1) s(-1) during the diurnal peak from spring to autumn, respectively, three times greater than those measured for Merlot on the drought-sensitive rootstock 101-14Mgt. The drought-tolerant root system grew more roots at depth during the warm summer dry period, and the whole JNK-IN-8 root TPCA-1 research buy system conductance (k(r)) increased from 0.004 to 0.009 kg MPa-1 s(-1) during
that same time period. The changes in k(r) could not be explained by xylem anatomy or conductivity changes of individual root segments. Thus, the manner in which drought tolerance was conveyed to the drought-sensitive clone appeared to arise from deep root proliferation during the hottest and driest part of the season, rather than through changes in xylem structure, xylem density or stomatal regulation. This information can be useful to growers on a site-specific basis in selecting rootstocks for grape clonal material (scions) grafted to them.”
“In this work, infrared spectroscopy was used to characterize the degree of double bonds conversion (DC) in six series of poly(urethane-dimethacrylate)s, derived from dicarbamates of oligoethylene glycols mono-methacrylates and aliphatic, cycloaliphatic and aromatic diisocyanates. To evaluate the degree of conversion in polymers Torin 2 supplier devoid of aromatic moieties, two methods of calculation have been proposed: internal band ratio method, with carbonyl stretching vibrations as a standard, and a method involving the direct observation of the decrease in the intensity of C=C stretching band. The validity
of these methods has been checked on polymers with aromatic structures, by comparing the results with those obtained by the internal band ratio method applying an aromatic band as a reference. A good correlation between the degree of conversion from two internal standard methods, using aromatic band and carbonyl band as references, was obtained. It was shown that the degree of conversion increases as the number of oxyethylene units increases. Polymerization of monomers with aliphatic cores resulted in higher DC values, while those with cycloaliphatic and aromatic cores-resulted in lower DC values. (C) 2011 Wiley Periodicals, Inc.
