A cau.sal relationship between growth substances and sex expression probably exists in Cucumis sativus L. (cucumber). This.assumption is based on a number of publications which documented a shift towards femaleness in monoe,cious cucumbers treated with auxins (8), or with growth retardants (16). An even more remarkable shift, but towards maleness, was caused by gibbe,rellins (24). The experimental modification of sex expression of C. sativus and other plant species by growth substances was… 

Sex expression in cucumber plants as affected by 2-chloroethylphosphonic Acid, ethylene, and growth regulators.

It seems, therefore, that Ethrel and gibberellins are not antagonistic but rather have different sites of action, although they have opposing effects on sex expression.

Contents and recovery of gibberellins in monoecious and gynoecious cucumber plants.

Results support the idea that endogenous GAs play a part in the regulation of sex expression in cucumber, relatively high levels of gibberellin-(GA-) like substances favoring the formation of staminate flowers.


Development of techniques effecting staminate Induction on gynoeclous phenotypes which normally produce abortive stamen less male buds and potential benefits of this phenomenon to breedIng efforts and/or to hybrId seed production were discussed.

Modification of sex expression in sponge gourd (Luffa cylindrica L.) roem by mineral nutrient treatments

Effects of three major mineral nutrient elements, nitrogen, phosphorous and potassium, on sex expression in Luffa cylindrica (L.) Roem were investigated in relation to nodal location of the first

Effect of IAA on flowering responses , metabolites and enzymes in Cucumis sativus

Seeds of cucumber,Cucumis sativus L., variety Jyoti Green Long, were exposed in different concentrations of IAA (0 – as control, 25, 50 and 100 mg L), for varying durations (24, 48 and 72 hr). After

Transport and Metabolism of 3 H-Gibberellin A 1 in Dioecious Cucumber Seedlings 1

The transport of 3H-GA1 through hypocotyl segments of cucumber (Cucumis sadivus L.) was found to be nonpolar. The transport of 3H-GA1 was increased by pretreatment with relatively high concentrations

Auxin, biosynthesis of ethylene and sex expression in cucumber (Cucumis sativus)

It appears that although exogenous IAA enhances ACC and ethylene production, endogenous IAA might not have a major role in the control of sex expression in cucumber of the Beit-Alfa type.

Increasing Hermaphrodite Flowers using Plant Growth Regulators in Andromonoecious Jatropha curcas

The aim of this study was to increase the proportion of hermaphrodite flowers by using plant growth regulators (PGRs) in andromonoecious JC, and the number of fruit per plant increased in those specimens treated with IAA, GA3, and kinetin at 50 and 100 ppm.

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

The literature on the possible involvement of plant growth substances (PGS) in male sterility, and in normal stamen and pollen development, supports the suggestion that it is the relative ratio of various PGSs, rather than any one substance, that is critical for normal stamens and pollenDevelopment.



Isolation of indole-3-acetic acid from corn kernels & etiolated corn seedlings.

The objective of the present study is to isolate free TAA from vegetative plant tissue using sufficiently rigorous isolation and assay procedures to establish its idlentity.

Changes in Sex in the Hop caused by Plant Growth Substances

The production of male flowers by a genetically female plant was noticed during an experiment to test the effects of certain systemic chemicals on the hop plant, but the phenomenon has not been reported in the variety Fuggles.


A detailed analysis of endogenous auxin revealed a linear basipetal decrease in diffusible auxin within the growing region, which suggested that the auxin transport system within this region had special properties related to a transition between shoot and root.

The Growth Substances separated from Plant Extracts by Chromatography. I

The procedure of chromatography described is shown not to involve a loss of indole-3-acetic acid activity if chromatography is done in darkness and chromato grams are not stored in light and air.


The evidence concerning the modification of sex expression in the sporophytes of flowering plants by external agencies, excluding those which act through genetical paths, is summarized.

Gibberellin as Sex Regulator in Ricinus communis

Spraying monoecious inbreds with gibberellin A3 can markedly increase their female tendency. The effect of this substance upon sex appears to simulate the action of long days

Microdiffusion Analysis and Volumetric Error

MICRO-DIFFUSION analysis represents a real advance in modern analytical technique. It seems strange, in fact, that the underlying principle of allowing the gaseous product of a reaction to diffuse,
