Other claims from this paper (15)

Intervention effect High BA induced multiple shoots and high hyperhydricity.
Intervention effect Low BA supported single-shoot growth with relatively low hyperhydricity.
Observation Hyperhydric cultures varied in glassiness or failed to grow after subculture.
Observation Shoot tips and upper nodes from slightly hyperhydric shoots often grew normally.
Observation Lower nodes tended to produce glassy growth.
Intervention effect RO medium gave better growth and less hyperhydricity than MS.
Intervention effect Increasing gelling agent reduced hyperhydricity.
Intervention effect Replacing phytagel with agar reduced hyperhydricity.
Intervention effect Mannitol and sorbitol in medium reduced hyperhydricity.
Intervention effect Vessel aeration reduced hyperhydricity.
Observation Aeration was relatively superior to other hyperhydricity controls.
Intervention effect More aeration caused faster medium dehydration and limited growth.
Intervention effect Combined low BA, osmotic agents, agar and aeration checked hyperhydricity with satisfactory growth.
Observation The combined approach could restore normal growth in hyperhydric stocks.
Intervention effect Single-shoot propagation with low BA gave better multiplication and normal plants than multiple-shoot induction with high BA.

Other claims from this paper (12)

Observation Liquid-cultured S. lateriflora plantlets were hyperhydric.
Observation Liquid-cultured S. lateriflora accumulated the greatest dry mass.
Association S. lateriflora multiplication diminished as hyperhydricity developed.
Intervention effect S. costaricana plantlets had higher fresh and dry weight on agar.
Intervention effect S. baicalensis plantlets had higher fresh and dry weight on agar.
Observation Plantlets of all tested Scutellaria species grown on agar or fiber-supported paper were not hyperhydric.
Intervention effect Fiber-supported paper with 20 mL initial volume gave Scutellaria plants the greatest percent dry weight.
Observation Baicalin concentrations in cultured S. lateriflora shoots were comparable to field-grown plants.
Method / resource The in vitro method could enhance baicalein content.
Method / resource The in vitro method could produce wogonin-rich roots.
Observation S. costaricana plantlets had high levels of three flavonoids relative to the other two species.
Method / resource Fiber-supported paper allowed clonal propagation with increased flavonoid content.

Association Agar concentration was related to hyperhydricity symptoms of Lavandino axillary shoots.
Method / resource A reproducible in vitro propagation procedure was established for Mentha piperita L.
Association The method of supplying cytokinins affected proliferation percentage in Mentha piperita.
Intervention effect Explant orientation changed BA absorption.
Method / resource Ajuga reptans explants were micropropagated as a source for callus production.
