Utilization of sugars and starch as carbon sources in the rooting of etiolated stem segments of populus nigra
K. K. Nanda,M. K. Jain +1 more
TL;DR: Stem segments of Populus nigra L. did not root in water or auxin alone but did so in 0.5% ribose, glucose and sucrose, sucrose being most effective and the addition of 0.1 mg/1 IAA or IBA to the medium stimulated rooting.

Abstract: Summary
Stem segments of Populus nigra L. did not root in water or auxin alone but did so in 0.5% ribose, glucose and sucrose, sucrose being most effective. The addition of 0.1 mg/1 IAA or IBA to the medium stimulated rooting; IBA being more effective. Starch also induced rooting especially in combination with auxins. Starch was hydrolysed by enzymes that leached out of the segments and auxins enhanced their activity.

Metabolic and Non-Metabolic Roles of Carbohydrates
Michael R. Thompson,Trevor A. Thorpe +1 more
- 01 Jan 1987
TL;DR: The development of photoautotrophism may be incompatible with many applications of plant tissue culture technology, themselves requiring specific hormone levels and balances, and thus the exogenous carbohydrate supply may be regarded as essential for successful culture.

The role of sucrose and nitrogen in adventitious root formation on cultured rose shoots
TL;DR: When the sucrose and nitrogen concentrations were both varied, the greatest rate of root initiation occurred on shoots grown in media with a high sucrose to nitrogen concentration ratio, which was related to the metabolism of sucrose rather than its osmotic properties.

Starch depletion and anatomical changes during the rooting of Castanea sativa Mill. cuttings
TL;DR: Great starch depletion following hormonal treatment could provide the energy necessary for the great cell proliferation observed at 3–5 days, the organization of the primordia and the differentiation of the new xylem.

Seasonal changes in auxin effects on rooting of stem cuttings of Populus nigra and its relationship with mobilization of starch.
K. K. Nanda,V. K. Anand +1 more
TL;DR: The results demonstrate that auxin effect on differential rooting with season in this plant is determined by the physio-morphological status of the branches that govern the production of endogenous auxin and is mediated primarily through its effect on mobilization of reserve food materials caused by enhanced activity of hydrolytic enzymes.

Secretion of α-amylase by Rumex virus tumors in vitro. Properties and assay☆
Myron K. Brakke,Louis G. Nickell +1 more
TL;DR: The existence of an extracellular α-amylase, which is secreted by virus tumors from the roots of Rumex acetosa grown in vitro, has been demonstrated and the properties of the enzyme have been studied.

Interaction effects of glucose and auxins in rooting etiolated stem segments of salix tetrasperma
K. K. Nanda,M. K. Jain +1 more
TL;DR: The results show that auxin effects on rooting are influenced by nutritional status of stem cuttings and that a proper balance of the two is necessary for this purpose.
