    Notes: Third-order harmonic generation has been measured on highly oriented polydiacetylene (PDA) films prepared by the vacuum deposition method. Experimental values of the third-order electric susceptibility χ(3) measured for pumping laser polarized parallel to the polymer chain show a sharp three-photon resonance to the 1Bu exciton in PDA. Potential usefulness of these highly oriented PDA evaporated films in nonlinear optical applications is suggested.

    Voltage-activated potassium, but not calcium currents in cultured bovine aortic endothelial cells (1987)

    Notes: Abstract The electrophysiological properties of cultured bovine aortic endothelial cells were characterized using the patch clamp technique. Resting potentials were measured on passing to the whole cell recording configuration and were close to −65 mV in healthy cells. In cell-attached recordings with a high potassium pipette solution, inward single channel currents were observed with zero applied pipette potential. A linear slope conductance of 25 pS was found for a wide range of hyperpolarizing patch potentials and also for depolarizing patch potentials of up to 50–60 mV. A pronounced inward rectification was apparent as no reversal of these currents was seen for larger depolarizations. Whole cell recording in physiological solutions revealed the presence of a hyperpolarization-activated inward current with strong inward rectification and no voltage-dependent ionic current was observed upon depolarization in this subset of cells. Substitution of potassium for external sodium resulted in a shift in the zero current potential consistent with potassium being the main permeant ion. Together with the characteristic voltage-dependent blocking actions of external sodium ions and low concentrations of barium and caesium ions, our results indicate that this current is very similar to the classical inward rectifier as originally described in skeletal muscle and in tunicate eggs. In a second population of cells, a depolarization-activated outward current displaying characteristics of the fast transient A-type potassium current as first reported in molluscan neurones was also observed. No evidence for inward voltage dependent sodium or calcium currents was found.

    Improving grain yield in backcross populations from Avena sativa × A. sterilis matings by using independent culling for harvest index and vegetative growth index or unit straw weight (1987)

    Notes: Summary Grain yield was selected in Avena sativa X A. sterilis populations of segregates by applying independent culling for harvest index and either vegetative growth index or unit straw weight. Samples of lines intensively selected for harvest index had high harvest index but low grain yield because they had low vigor. Populations intensively selected for growth rate index or unit straw weight had high biological yield but low harvest index. Intensive selection for grain yield per se resulted in samples with high grain yield, but they were late and tall. Samples selected for harvest index at a 25% selection intensity first and subsequently selected for vegetative growth index or unit straw weight had grain yield as high as the samples selected for grain yield per se and vegetative growth index, and they had acceptable heading date and plant height. Backcrosses three and four were best, among the various BC generations, for selecting oat lines with high grain yield and suitable agronomic traits. CI 7463 was superior to CI 8044 as a recurrent parent, and B 445 was inferior to other A. sterilis accessions as a donor parent.

    Simultaneous selection for grain yield and protein percentage in backcross populations fromAvena sterilis ×A. sativa matings by using the independent culling levels procedure (1985)

    Notes: Summary The method of independent culling levels was applied for simultaneous improvement in grain yield, protein percentage, and protein yield in a population of oat lines from the BC0–BC5 of the interspecific matingAvena sativa ×A. sterilis. Grain yield and protein percentage were subjected to selection with various combination of culling levels to give samples with 2% of the lines from the original population. — Intense selection for grain yield resulted in samples with high grain and protein yields but low protein percentage. Intense selection for protein percentage resulted in samples with high protein percentage but low grain and protein yields. The sample selected for protein yield only showed no significant difference from the recurrent parent for any trait. The recommended regime for improving protein percentage and grain and protein yields simultaneously was one that initially saved approximately 25–50% of the original population on the basis of protein percentage, and then provided intense selection for grain yield on the lines that remained. At least three backcrosses were necessary to obtain lines with high protein percentage and acceptable agronomic traits.

    Notes: Summary Most variation in grain yield of oats is due to variation in harvest index and vegetative growth index, but the latter traits are negatively associated. Therefore we used independent culling levels to select oat genotypes with high levels of vigor traits and a desirable level of harvest index in an attempts to maximize grain yield. Harvest index and vegetative growth index or harvest index and unit straw weight were selected at various culling levels. Intensive selection for harvest index resulted in high harvest index but no grain yield improvement, because the selected lines had poor vigor. Intensive selection for vegetative growth index or unit straw weight resulted in high biomass but low harvest index. The most effective combination of culling levels was to select 25% of the original population for harvest index and, subsequently, to select for vegetative growth index or unit straw weight at an 8% intensity in the remnant population.
