The ability of the plant to reproduce vegetatively is widely used in horticulture and these methods, both natural and artificial, are detailed in … Since most citrus improvement programs involve the use of seedlings, plants with reduced juvenility will prove invaluable for expediting work that is based in conventional breeding, biotechnology, or a combination of the two due to a shorter time period required for screening, evaluations and/or subsequent crosses. Juvenility is the early phase of plant growth, from seed germination, during which flowering cannot be induced.

%%EOF Maturity is the state of growth during which the plant becomes capable of flowering. The change from mature to senescent conditions typically involves the deterioration of many synthetic reactions leading to the death of the plant, thereby completing the cycle. Plant juvenility. juvenility. PDF | Juvenility is referred to the period during which a plant cannot be induced to flowers whereas maturity is occurred if a plant gives flowers. 2. The reproductively incompetent juvenile vegetative phase of seed plants, often with morphological and physiological characteristics that differ from those of an adult plant. 137 0 obj <>stream 0 Objectives: 1. 3. It is important as it affects when a plant can become reproductive. In annual plants, this state is very short (perhaps a month or two), whereas in longer-lived species, a healthy, actively growing plant may exist in the juvenile stage for years. Adult growth should be removed from stock plants (see p174) to leave the more successful juvenile growth for cutting. Once the plant reaches maturity, flowering can be induced by appropriate external cues.
