  Extract from Propagation 1 BHT108 LIFE CYCLES IN PLANTS  There are basically two different types of developmental life cycles in plants: sexual and asexual. These phases have a significant influence on the techniques used by propagators. Phases of the Sexual Cycle   There are three phases in this cycle:   1. The embryo phase – the union of male and female gametes in the flower forms a single-celled zygote. The resulting embryo develops within the fruit and seed.   2. The juvenile phase – the seed germinates and the embryo grows into a juvenile plant. At this stage, many plants respond well to vegetative propagation techniques but will not respond to flower-inducing stimuli. 3. The adult phase – the plant reaches its ultimate size and develops flowers in response to environmental signals (e.g. change in day-length or temperature) or internal hormonal stimuli. The plant may change in its morphological appearance including leaf shape and growth habit. It may be more difficult to propagate by vegetative means but has better response to flowerinducing stimuli.  In some plants both the juvenile and adult phases can be found in the same plant at one time.    Phases of the asexual cycle  There are two phases in the asexual cycle: 1. Vegetative phase – this phase involves the growth of the plant: roots, leaves and stems increase in length, and the plant increases in volume. 2. Flowering phase – the stems stop growing, and the growing points differentiate into flower buds that eventually produce flowers, fruits and seeds. Sage at flowering phase   Types of Life Cycles Life cycles of plants can be classified as annual, biennial and perennial, depending on how long it takes for the plant to grow through the sexual cycle from zygote to seed production.   Annuals – plants go through the entire life cycle in one season, i.e. seeds germinate, grow and produce flowers and seeds, then die in the same growing season. Biennials – plants have a two-year life cycle, i.e. seeds germinate and remain in a vegetative or juvenile state for one season. They remain dormant over winter then produce flowers and seeds in the second season then die. Biennial – Carum carvi Perennials – plants live more than two years; each year they go through the vegetativereproductive cycle. • Herbaceous perennials are plants that have shoots that die back each winter or in dry periods, then re-grow and flower the following season. They have specialised underground storage organs such as bulbs, rhizomes or crowns that enable them to survive the dormant period.   • Woody perennials continue to increase in size every year.                                               Herbaceous perennial - Nepeta faasenii   Woody perennial – Lavandula sp. TERMINOLOGY Sexual propagation: A method of propagation that requires the union (fertilization) between the male and female gametes to from a single cell (the zygote) within the ovary of a flower. New plants show variability to that of the parents as it has both features. Asexual propagation:  A method of propagation that involves no fusion between the male and female gametes. These methods result in a plant that is identical to the parent plant. Techniques include cuttings, division, separation, layering, tissue culture, etc.   Stool bed layering: Sometimes called mound layering or stooling. Healthy plants are planted in loose friable soil one year before propagation is to start. Before mother plants start shooting in spring, they are cut back to 2.5cm above the ground level. When they are 7-12 cm long, loose soil or sawdust is heaped up around each shoot to about half its height. When shoots have grown to a total height of about 20-25cm, a second hilling operation takes place. A third and final hilling usually takes place in mid-summer when shoots have reached about 45cm. At this stage the base of the shoots will have a covering of about 15-20cm.  By the end of the growing period, stool shoots should have rooted sufficiently to be removed form the parent plant. Hilling may restart the following year. This technique has been used for plants such as apple and pear rootstocks, quince, currants and gooseberries.   Separation: A method of asexual propagation which involves the pulling apart of immature plants from one-another. Bulbous plans such as daffodils can be separated for one-another.   Division: A method of asexual propagation involving the cutting away of plants from the parent plant. Clump forming plants are the most commonly divided plants. Use of two garden forks backto-back pushed into the plant then teased apart is a common technique of division. Plant parts that are cut should be severed with a sharp clean instrument such as a knife or secateurs.   Root cuttings: A method of asexual propagation utilizing root pieces taken from young stock plants in late winter or early spring. It is important to maintain the correct polarity when planting (to avoid confusion many propagators cut the upper end flat and the lower end at a slight angle). When planting, insert cutting vertical so that top of cutting is at soil level. With many species, laying the cutting horizontally 2.5 - 5 cm deep works quite well and avoids the confusion of planting upside down.   Leaf bud cuttings: A method of asexual propagation consisting of a leaf blade (lamina), petiole, and a short piece of the stem with the attached axillary bud. Top grafting: Also called top working. To change the cultivar of a tree by grafting the main scaffold branches.   Budding: A form of grafting; a single vegetative bud is taken from one plant and inserted into stem tissue of another plant so that the two grow together as one plant. The inserted bud develops into a new shoot.   Aerial layering: Also called marcott; an unattached aerial portion of a plant on which roots are caused to develop commonly as the result of wounding or other stimulation.   Offsets: Term given to full sized bulblets (miniature meristematic bulbs in the axils of bulb scales). Approach grafting: Two independent, self-sustaining plants are grafted together. After the union has occurred, the top of the stock plant is removed above the graft and the base of the scion plant is removed below the graft. It is normally performed with one or both of the plants in containers. It is commonly used for plants where grafting is not so successful. It is best done when growth is active and rapid healing of graft union should occur. There are three methods of approach grafting: spliced, tongued and inlay.
