Dormancy in Plants: From Whole Plant Behaviour to Cellular Control

| Tóm tắt: | The longevity of plant species ranges from a few weeks, e.g. desert annuals,
to thousands of years, e.g. Dracaena draco. Life spans for clonal species are
longer and some may have persisted since the time of the last glacial period.
Starting with the gamete to fertilized egg, the developmental history of a
plant is traced through seed development, germination, juvenility, maturity,
flowering and fruiting. At fruiting, the basic cycle of plant growth is
complete. In annuals, fruiting is the beginning of senescence and death,
whereas in perennials, the plant is prepared to recycle after a period of
quiescence. One growth cycle, therefore, corresponds to one life cycle in
annuals, whereas in perennials the life span consists of repeated growth
cycles. What is one growth cycle in tomato plants? At lower nodes of a
growing tomato plant, fruits are maturing, whereas at the upper nodes,
flowering is occurring while the apical meristem is vegetative. It grows as an
annual in temperate regions and a perennial in the tropics. |
