Photosynthetic potentials of in vitro-grown juvenile, adult, and rejuvenated Sequoia sempervirens (D. Don) Endl. shoots
In vitro shoot tips of Sequoia sempervirens (D. Don.) Endl.including a juvenile, two adult, and two rejuvenated adult cloneswere examined for differences in basic physiological characteristics. Moisture contents were the same, around 85%, for all tissues regardless of origin. Growth rates, determined by fresh weight increase and shoot elongation, were higher for the juvenile and rejuvenated s...
متن کاملAssociation of mitochondrial plasmids with rejuvenation of the coastal redwood, Sequoia sempervirens (D. Don) Endl
Repeated grafting of shoot apices from mature Sequoia sempervirens (D. Don) Endl. trees onto young seedling shoots in vitro causes emergence of rejuvenated, or phase-reversed, scion shoots. The phase reversal is indicated by a restored rooting competence and renewed vigor of roots and shoots. We earlier reported of restriction fragment length polymorphism between juvenile or rejuvenated and adu...
متن کاملThe water relations and xylem attributes of albino redwood shoots (Sequioa sempervirens (D. Don.) Endl.)
Plants that lack chlorophyll are rare and typically restricted to holoparasites that obtain their carbon, water and mineral resources from a host plant. Although not parasites in the traditional sense, albino foliage, such as the sprouts that sometimes develop from redwood tree trunks, are comparable in function. They occur sporadically, and can reach the size of shrubs and in rare cases, trees...
متن کاملRhizonema sequoiae n.gen. n.sp. from Coast Redwood Sequoia sempervirens (D.Don) Endl.
Rhizonema sequoiae n.gen, u. sp. is described from the roots of Coast Redwood, Sequoia sempervirens (D. Don) Endl., growing near Lake Lagunitas, Marin County, California. Rhizonema females are annulated over their entire bodies, are wholly embedded in host tissue, and secrete an abundant amount of gel material. Mature females do not form a cyst. The vulva is located on a large posterior termina...
متن کاملIncidence, size and spatial structure of clones in second-growth stands of coast redwood, Sequoia sempervirens (Cupressaceae).
The ecology and evolutionary potential of coast redwood (Sequoia sempervirens) is significantly influenced by the important role clonal spread plays in its reproduction and site persistence. In nine second-growth stands, amplified fragment length polymorphisms (AFLPs) were used to identify redwood clonal architecture. Clones (multistem genets) dominated sites by representing an average of 70% o...
