How do plant growth substances work? II

, 1981
. Despite intensive research effort, the role of growth substances in the life of the intact growing plant is far from clear. Two reasons are suggested which may account for the lack of progress.

EFFECTS OF PLANT GROWTH SUBSTANCES ON IN VITRO FIBER DEVELOPMENT FROM UNFERTILIZED COTTON OVULES

, 1973
Fertilization of cotton ovules was prevented by removal of styles and stamens on the morning of anthesis. Forty-eight hr later ovaries were harvested and ovules were aseptically transferred to liquid culture medium supplemented with various plant growth ...

Is Heteroauxin a Growth-Promoting Substance?

American Journal of Botany, 1937
SUCH A VOLUMINOUS literature has grown around auxins that it is neither possible nor advisable to include a comprehensive survey of it within the scope of a short paper. The reader is referred to Boysen Jensen's (1936) book, which treats the subject very exhaustively.

Male sterility in flowering plants: are plant growth substances involved?

, 1994
Male sterility in flowering plants is of tremendous importance not only in molecular and developmental studies of stamen and pollen grains and evolutionary studies on the origin of dioecy, but also in its commercial application in hybrid seed production.

Growth Substances in Fruit Setting and Development

, 1964
Nitsch (112), in his review of this subject in 1953, pointed out that fruit setting and growth were obviously under a control mechanism and presented the evidence for auxin originating in the seed as being the key factor involved.

GROWTH SUBSTANCES IN HIGHER PLANTS

Annual Review of Biochemistry, 1947
hensively covered but it is hoped that the main results obtained and the maj r trends of development will be indicated. Other reviews and general presentations of the subject which have ap­ peared recently or are in process of publication are by Went (2), Zimmerman (3), Bonner (4), Thimann (5) and Thomson (6) .

Growth Substances and Protoplasts [PDF]

, 1977
The removal of the cell wall of higher plant cells enables protoplasts to be isolated. Current work involves attempts to detect any specific effect of growth substances on the plasma membrane, including reactions leading to the regeneration of a cell wall.

The mechanism of action of plant growth substances: The role of nuclear RNA in growth substance action

Biochimica et Biophysica Acta (BBA) - General Subjects, 1965
Abstract Indoleacetic acid, gibberellic acid or kinetin stimulate the synthesis and release of nuclear RNA. The presence of the nuclei is essential for the growth substance-induced promotion of RNA synthesis. The induced stimulation is abolished by actinomycin D but can be restored partially or completely by relatively higher concentrations of the ...

Effect of External Supply of Growth Substances on Axillary Proliferation and Development in Dioscorea bulbifera

, 1971
Bulbil development in cultured nodes of D. bulbifera proceeded in the absence of growth substances from the medium. When IAA was incorporated into the medium at the concentrations of 5 mg l−1 and 10 mg l−1 the cultured nodes produced larger bulbils than ...

Effects of growth substances on the protoplasmic drought tolerance of leaf cells of the resurrection grass, Sporobolus stapfianus

, 2001
Hydrated leaves of the resurrection grass Sporobolus stapfianus Gandoger are not desiccation tolerant, but moderate to severe drought stress can induce their desiccation tolerance while the leaves remain attached to drying intact plants.
