The biosynthesis and production of hypoxoside in Hypoxis hemerocallidea Fisch. and Mey. in vivo and in vitro.
Hypoxoside, a phenolic diglucoside, with a diarylpentane-type structure, is thought to be the medicinally active constituent of corm extracts of Hypoxis hemerocallidea Fisch. & Mey. which are reputed to alleviate the ...
Cytokinins in Ecklonia maxima and the effect of seaweed concentrate on plant growth.
The endogenous cytokinin levels in the brown alga Ecklonia maxima (OSBECK) PAPENF., and the effect of applications of the seaweed concentrate (Kelpak 66) prepared from this alga, on the growth and yield of various ...
The regeneration of Hypoxis rooperi S. Moore and production of hypoxoside in vitro.
Against the background of the increasing pharmaceutical importance of members of the genus Hypoxis L., methods for propagating these plants and for producing hypoxoside (the believed active compound found within Hypoxis ...
Hormonal regulation of tuberization of cassava (Manihot esculenta Crantz)
The relative distribution of dry matter over shoot and tuberous roots is an important factor in determining the yield of cassava. Under sub-tropical conditions the dry matter distribution pattern is not always efficient. ...
The biochemical and cytokinin changes in the developing and germinating seeds of Podocarpus henkelli stapf.
A review of the literature revealed that there is a lack of depth in our knowledge of gymnospermous seeds with regard to the development and germination processes. The phytohormones, particularly the cytokinins have ...
The role of cytokinins in the regulation of apical dominance in Pisum sativum.
Intact or decapitated Pisum sativum seedlings were used to investigate the correlative inhibition of lateral buds by the shoot apex - a developmental process known as apical dominance. Apical dominance is considered to ...
Tissue culture of selected indigenous monocotyledons.
Components of the South African indigenous flora are disappearing at an alarming rate, due to pressures on land use. The flora is protected by proclamation of reserves and conservation legislation, however these measures ...
An investigation into in vitro culture and phytochemical aspects of some members of the order Cycadales.
The present-day cycads represent the diverse, modified remnants of a much larger group of gymnosperms which flourished in the Mesozoic Era. The approximately 148 surviving species of the Cycadales are sparsely distributed ...

Adventitious rooting in stem cuttings of Eucalyptus grandis Hill ex Maid.
Adventitious rooting in stem cuttings of Eucalyptus grandis Hill ex Maid. was thought to be influenced by a putative inhibitor. In previous studies it has been usual to infer the presence of putative rooting inhibitors ...
