Leaf morphogenesis in flowering plants.
Leaves, or organs derived from leaves, are the most morphologically diverse structures in a plant (Gifford and Foster, 1989). They occur as prominent photosynthetic structures; as inconspicuous fragments of tissue in tubers, rhizomes, and the stems of many cacti; as nonphotosynthetic storage organs in bulbs; and, in carnivorous plants, as complex structures specialized for catching and digestin...

متن کاملMethods for growth regulation of greenhouse produced ornamental pot- and bedding plants – a current review
Chemical plant growth regulators (PGRs) are used in the production of ornamental potted and bedding plants. Growth control is needed for maximizing production per unit area, reducing transportation costs and to obtain a desired visual quality. However, the use of PGRs is associated with toxicity risks to humans and the environment. In many countries the availability of PGRs is restricted as few...
متن کاملThe Influence of Day and Night Temperature Fluctuations on Growth and Flowering of Annual Bedding Plants and Greenhouse Heating Cost Predictions
Volatile energy costs and lower profit margins have motivated many greenhouse growers in temperate climates to improve the energy efficiency of crop production. We performed experiments with dahlia (Dahlia ·hybrida Cav. ‘Figaro Mix’), French marigold (Tagetes patula L. ‘Janie Flame’), and zinnia (Zinnia elegans Jacq. ‘Magellan Pink’) to quantify the effects of constant and fluctuating temperatu...
متن کاملConditioning Treatments Affect Insect and Mite Populations on Bedding Plants in the Greenhouse
During greenhouse production in Spring 1995, conditioning treatments were applied to columbine (Aquilegia ×hybrida Sims ‘McKana Giants’), New Guinea impatiens (Impatiens hawkeri Bull. ‘Antares’), marigold (Tagetes erecta L. ‘Little Devil Mix’) and ageratum (Ageratum houstonianum Mill. ‘Blue Puffs’) plants. Treatments included: mechanical conditioning (brushing 40 strokes twice daily); moisture ...
