Phenotypic reversion of flacca, a wilty mutant of tomato, by abscisic Acid.
Dorot Imber,Moshe Tal +1 more
TL;DR: Application of abscisic acid to intact mutant plants changes their morphology toward the phenotype of the control normal variety, Rheinlands Ruhm, and the resistance to closure of their stomata decreases with hormone treatment.

Journal ArticleDOI
Primary, preventive and permissive roles of hormones in plant systems
TL;DR: It is explained for the first time that seed dormancy can occur not only in presence of inhibitors as was generally believed but in many cases in absence or presence of promotors such as gibberellins or cytokinins.

Control of ribonuclease and acid phosphatase by auxin and abscisic acid during senescence of Rhoeo leaf sections.
Pietro De Leo,Joseph A. Sacher +1 more
TL;DR: Evidence suggests that the increases in hydrolase activity could result from new enzyme synthesis and the possible significance of hormonal regulation of enzyme activity and senescence is discussed.

The identification of (+)-abscisin II [(+)-dormin] in plants and measurement of its concentrations
TL;DR: Identification of several previously described growth-inhibitory compounds as (+)-abscisin II has extended the known physiological effects of the compound; its roles as a dormancy and an abscission factor and as a germination inhibitor are discussed.
Journal ArticleDOI
Some physiological responses to d,l abscisin (dormin).
TL;DR: Synthetic d,l abscisin accelerates the senescence of leaf discs of a wide variety of species, but is less effective when sprayed on to attached leaves, except at relatively high concentrations (50–100 ppm).
Journal ArticleDOI
Dormin (Abscisin II), inhibitor of plant DNA synthesis?
TL;DR: Separation, after phenol-detergent extraction, of nucleic acids on methylated albumin kieselguhr columns showed suppression of nuclei acid synthesis by dormin in all fractions, and inhibition of the synthesis of the DNA fraction seems to precede that of RNA.

Reversal of (±) ‐Abscisin II Induced Inhibition of Lettuce Seed Germination and Seedling Growth by Kinetin
N. Sankhla,D. Sankhla +1 more
TL;DR: In this article, the effect of abscisin II alone and in combination with kinetin and indoleacetic acid on seed germination and seedling growth of two strains of lettuce, cv Attraktion and cv Hohlblattriger Butter, was investigated.
Journal ArticleDOI
Increase in chromatin associated nuclease activity of excised barley leaves during senescence and its suppression by kinetin
TL;DR: No significant changes in the composition of chromatin were found when the excised barley leaves were floated on water or on kinetin solution in the dark, but increases in the activities ofchromatin associated ribonuclease and deoxyribonucleasing in leaves floated onWater drastically suppressed the increases in these enzymes.
