The growth of sun and shade leaves of Populus euramericana "robusta" in relation to age, light intensity and temperature...
The growth and development of sun and shade leaves was investigated in Populus euramericana 'Robusta', growing under various light intensities and temperatures and on a substrate optimal for the roots.Strong correlations exist between the dimensions of the various plant parts. The width of an individual growing leaf is always 2 cm smaller than its ...
De invloed van de groeiregulatoren CCC, B9 en 2-chlooraethaan phoshonzuur in ver uiteenlopende concentr. op chrysanten
The influence of photoperiod, dormancy breaking and growth hormone treatment on poplar cuttings
Bijdrage tot de kennis van den groei van Pseudotsuga taxifolia Britton in Nederland in verband met zijn beteekenis voor ...
Development of the green Douglas fir in the Netherlands in different places with different methods of planting was studied by enquiry, personal research and from the literature. The climate and soil types seemed suitable. Game, insects and fungi caused little damage. The stands studied all derived from seed from north-west America but the exact ori...
Effects of gibberellic acid and prohexadione-calcium on growth, chlorophyll fluorescence and quality of okra plant
Published in Biologia Plantarum
The experiment was conducted to identify the response of three cultivars of okra [Abelmoschus esculentus (L.) Moench] to exogenous hormones [gibberellic acid-(GA3) and prohexadione-Ca] applied as foliar spray. Stem and leaf dry masses and stem length were significantly enhanced by the application of exogenous GA3, but prohexadione-Ca inhibited grow...
Micropropagation of Chokecherry and Pincherry cultivars
Published in Plant Cell, Tissue and Organ Culture
In vitro culture establishment, shoot proliferation and ex vitro rooting responses of chokecherry (Prunus virginiana L.), `Garrington', and pincherry (P. pensylvanica L.f), `Mary Liss' and `Jumping Pound', were examined using various combinations of growth regulators. Dormant winter buds were used as explants. MSMO medium supplemented with 0.49 μM ...
Changes in Isozyme Patterns During in Vitro Regeneration from Cotyledon Explants of Brassica Species
Published in Biologia Plantarum
High frequency shoot regeneration from cotyledons excised from 4-d-old seedlings of Brassica campestris L. cv. M 27 and Brassica juncea (L.) Czern. cv. Pusabold was achieved on Murashige and Skoog's (MS) medium supplemented with 1.0 mg dm-3 N6-benzyladenine (BA) and 3 % (m/v) saccharose. Rooting occurred simultaneously with shoot formation on the m...
Plant regeneration via somatic embryogenesis in Pinus kesiya (Rolye ex. Gord.) influenced by triacontanol
Published in Acta Physiologiae Plantarum
Embryogenic cultures were initiated and established for the first time in 3 different genotypes of Pinus kesiya using mature zygotic embryos and triacontanol. Mature zygotic embryos produced white-mucilaginous embryogenic callus when cultured on half strength MSG (Becwar et al. 1990) basal medium supplemented with 90 mM maltose, 2.0 g l−1 Gellan gu...
