Grindelia chiloensis (Asteraceae) is a shrub native to Patagonia, Argentina, in the process of domestication as a source of resin to complement rosin production by pines. Vegetative propagation to multiply selected genotypes has produced breakthroughs in the cultivation of new crops like jojoba (Simmondsia chinesis). The only available way to propagate Grindelia is by transplanting seedlings or...

Abdulla, Fuad A. and Peter A. Smith. Axotomyand autotomyinduced changes in Ca and K channel currents of rat dorsal root ganglion neurons. J Neurophysiol 85: 644–658, 2001. Sciatic nerve section (axotomy) increases the excitability of rat dorsal root ganglion (DRG) neurons. The changes in Ca currents, K currents, Casensitive K current, and hyperpolarization-activated cation current (IH) that may...

It is shown that strong 0(+)(2)-->0(+)(1) E0 transitions provide a clear signature of phase transitional behavior in finite nuclei. Calculations using the interacting-boson approximation (IBA) show that these transition strengths exhibit a dramatic and robust increase in spherical-deformed shape transition regions, that this rise matches well the existing data, that the predictions of these E0 ...

Copolymers of Acrylonitrile with Isobornyl acrylate (IBA) and Isobornyl Methacrylate (IBM) were synthesized by free radical polymerization using AIBN as initiator in dimethyl formamide (DMF) at 60 ± 1°C. Thermo gravimetric analysis of the copolymers was performed and their thermal stabilities were studied. Thermal stability of IBM copolymers is found to be more than that of IBA copolymers. The ...

Radiomimetic action of growth substances, also called hormones, has been demonstrated by several workers Some of the growth substances are used as growth promotors while others are used as herbicides for weed control. As they prove toxic beyond certain concentrations, it is fruitful to study their effects at different concentrations. This paper describes the results of an experiment involving d...

ethylene as a plant hormone plays various functions in a variety of physiological phenomena including seed germination, root initiation on stem cutting, senescence and organs abscission. in our previous investigation, five rose genotypes were identified showing high-sensitivity or low-sensitivity to exogenous ethylene treatment. the purpose of this study was to evaluate the rooting capacity and...

The present study was conducted in Bangalore. It aims at studying the effect of different concentrations indole-3-butyric acid (IBA) (1000, 2000 and 3000 ppm) on V-1 mulberry cuttings with varying number buds (one, two, three four) consist twelve treatments which were replicated thrice Factorial CRD. results interaction various concentration IBA recorded best budded treated ppm regarding sprout...
