Morphogenesis of the root cap in adventitious roots of Salix viminalis

Nordic Journal of Botany, 1985
The preformed root primordia in stems of Salk viminalis L. consist of undifferentiated cells. Forty‐eight hours after activation of the primordia in cuttings a root cap meristem was initiated four to five cell tiers from the surface of the primordia.

THE ONTOGENY OF ADVENTITIOUS STEMS ON ROOTS OF CREEPING-ROOTED ALFALFA

Canadian Journal of Botany, 1957
An ontogenetic study of adventitious stem formation on root segments of creeping-rooted alfalfa clones is presented. Unusual meristematic activity is evident first in the phellogen near a lateral rootlet. Continued activity in that region gives rise to a primordial dome from which adventitious stems eventually emerge.

Commercial Importance of Adventitious Rooting to Agronomy

1994
Agronomic crops are those grown on a large scale, either for consumption by humans or livestock, or for production of raw materials. Those crops in which adventitious root formation is important can be divided into two broad categories—those that are vegetatively propagated and those for which final yield, whether fruit or dry matter, is influenced by ...

Adventitious roots in Kunzea triregensis (Myrtaceae)

Perspectives in Biodiversity
Adventitious roots are reported for Kunzea triregensis de Lange, an apparent first for this species and the Aotearoa / New Zealand indigenous representatives of Kunzea Rchb. It is noted that the roots were observed in a cultivated tree of this Manawatawhi / Three Kings Islands endemic that had been raised from a cutting.

Commercial Importance of Adventitious Rooting to Horticulture

1994
Vegetative or clonal reproduction is the most important propagation method used for the commercial production of many, if not most, horticultural crops (ornamentals, fruits, nuts and vegetables). One of the major advances in early agriculture was the discovery that important food crops such as figs, grapes and olives could be regenerated by inserting ...

Origin of Adventitious Roots in Cotoneaster dammeri

Botanical Gazette, 1934
1. Adventitious roots of Cotoneaster dammeri arise from only one of the two groups of parenchymatous cells in the divided bud gap. 2. Formation of the root primordium is apparently due to the resumption of activity of the parenchyma cells. 3. The cortical cells in the region of the bud axis produce a slight protuberance through which the young root ...

Strigolactones inhibit adventitious root formation [PDF]

, 2010
Adventitious root formation from a non-root tissue facilitates clonal propagation of elite plant varieties and is therefore central to many plant industries worldwide. However many plant species cannot be propagated in this way posing significant limitations particularly on the forestry and horticulture industries.

Auxin Metabolism and Adventitious Root Initiation

1994
In this chapter I will report on and discuss the role of auxins in adventitious root initiation, particularly the relations between endogenous indole-3-acetic acid (IAA) and the early events of adventitious rooting. The fact that IAA is involved is well established, although much of the data to support this is circumstantial. It will be not possible in

Commercial Application of Adventitious Rooting to Forestry

1994
Zhu Xi’s lyrical and evocative lines were penned over 800 years ago. The cuttings referred to are of the Chinese fir (Cunninghamia lanceolata [Lamb.] Hook.), China’s major timber producing conifer. A scrutiny of ancient Chinese literature led Li (1992a) to conclude that this species has been propagated by cuttings in China for over 1,000 years ...
