Spores of Dryopteris varia were germinated in Knop's solution. Just after the germination, before the original cell of protonema was cloven, the sporelings were transferred to solutions containing various chemical agents. As a result, the following was obtained.1) In IAA, at 100ppm, a rhizoid is formed at the terminal of the protonema where a papilla is to be formed in the normal development. At 1 to 10-2ppm, formation of the terminal papilla is abnormally accelerated so that it appears at an…

An Evaluation of Specific and Non‐Specific Inhibition of 2‐Dimensional Growth in Fern Gametophytes

TLDR
No firm evidence is available that inhibition of protein synthesis specifically blocks 2-dimensional growth and the proper criteria for establishing a specific inhibition of 2-dimcnsional growth arc discussed are applied.

CONSEQUENCES OF ULTRAVIOLET RADIATION ON THE DIFFERENTIATION AND GROWTH OF FERN GAMETOPHYTES

TLDR
It was ascertained that a single cell may be isolated by u.v.-irradiation and that a normal gametophyte can be regenerated from such a cell, and that cells of a definite length alone survive under both culture conditions.

Branching in Fern Gametophyte, Pteris vittata, under Various Light Conditions

TLDR
Light conditions seem to destroy a distinct apico-basal gradient of the physiological activity in the gametophyte, to alter the developmental axis and consequently to induce the branching.

Effect of linear alkyl benzene sulphonate on germination of spores of the aquatic fernCeratopteris thalictroides

TLDR
The phytotoxicity of LAS on germination of an aquatic fern Ceratopteris thalictroides spores was studied, but in these studies, only germination pattern was taken as index and no observations were made on the developmental stages.

Differential Germination of Fern and Moss Spores in Response to Mercuric Chloride

TLDR
A comparison of the germination responses of different fern and moss spores to divalent mercury is presented, finding that for the three metal ions tested, toxicity was directly proportional to atomic weight.

Appearance of “Metallophilic Cytoplasm” as a Prepattern to the Differentiation of Rhizoid in Fern Protonema

TLDR
The metallophilic cytoplasm could not be verified in rhizoids of the sporeling of a moss, Pogonatum inflexum, in root hairs of the seedling of some Angiosperm, Glycine Max, Raphanus sativus, and Triticum vulgare and it seems that it cannot be attributed to the attraction by the cy toplasm of metallic ions caused by difference in electric charge between the two.

THE DEVELOPMENT OF FUCUS EGGS IN CONCENTRATION GRADIENTS: A NEW METHOD FOR ESTABLISHING STEEP GRADIENTS ACROSS LIVING CELLS

TLDR
A simple new method for establishing very steep gradients across living cells is described, applicable to a wide variety of types of living cells, and the steepGradients may be either chemical or physical, including temperature and gas pressures as well as various water solutions.

THE ROLE OF AUXIN IN THE DIFFERENTIATION OF ROOT AND SHOOT PRIMORDIA FROM ROOT CUTTINGS OF TARAXACUM AND CICHORIUM

TLDR
It would appear that cutting disturbs the physiological unity of the root and causes a redistribution of some substance or substances, which in turn influences the direction of differentiation of the callus tissues formed on the two cut surfaces.

The effect of auxin on flower initiation.

TLDR
The structure of the chloroplast and the effects of plant virus diseases on the cells of their hosts are studied in detail.
