Regeneration, vernalization and flowering in Lunaria annua L. in vivo and in vitro
Lunaria annua L. is a species with a juvenile phase and requiring cold for flowering. An annual flowering mutant was obtained with ethyl methane sulphonate. Experiments with shoot and leaf cuttings showed that juvenility was not a character of the whole plant. The juvenile phase was shortened by regeneration of cotyledon cuttings of very young plan...
Effects of light and temperature on growth and flowering of carnation (Dianthus caryophyllus L.)
Both a long photoperiod and strong illumination strongly promoted growth and flowering. These conditions diminished the number of leaf pairs below the flower and promoted growth of flower buds from initiation to bud emergence from the leaves. The subsequent phases to anthesis were little affected by photoperiod and light intensity. Other characters...

Growth changes of plants following the removal of nutritional stresses
Differential changes in leaf area of plants were used to assess the fertility status of soils. For this method subterranean clover plants were raised in solutions with different levels of nutrients and transferred either into complete solutions or to solutions lacking one of the elements. Response of plants to addition of nutrients was measured by ...
