    Clonal propagation of Callistemon by tissue culture techniques (1982)
    Springer
    Plant cell reports 1 (1982), S. 199-201 
    Details
    ISSN: 1432-203X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Callus development in Callistemon viminalis was readily achieved when axillary buds derived from nodal tissue were placed in a medium containing macro- and micro-nutrients, sucrose (0.06 M), inositol (300 μM), nicotinic acid (20 μM), pyridoxine hydrochloride (3 μM), thiamine hydrochloride (2 μM), riboflavin (10 μM), cytokinins (5 μM) and auxins (0.1 μM). The presence of benzylaminopurine (5 μM) and p-chlorophenoxyacetic acid (0.1 μM) promoted the most vigorous callus development and sprout formation. Rooting of nodal material was rare but occurred readily following the transference of sprouts developed on callus to a basal medium containing sucrose and salts. Root initiation was stimulated, however, by the presence of auxins. Chlorophenoxyacetic acid while stimulating root initiation repressed root growth. Indole butyric acid stimulated both root initiation and shoot growth at concentrations of 0.005 to 0.1 μM. The treatment of choice for rooting and shoot growth was the addition of indole butyric acid at a concentration of 0.01 μM.

    Clonal propagation of Leptospermum spp. by tissue culture (1986)
    Springer
    Plant cell reports 5 (1986), S. 5-8 
    Details
    ISSN: 1432-203X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Propagation by axillary and multiple axillary bud development was achieved in three native Leptospermum spp. when axillary buds derived from nodal tissues ex mature plants were placed in benzylaminopurine media (0.04–1.0 μM) containing macro- and micro-nutrients, sucrose (0.06 M) and a vitamin/amino acid supplement. Reduction of agar concentration from 0.8 to 0.2% greatly stimulated axillary bud development and growth in L. flavescens and L. brachyandrum. Rooting of axillary shoots was stimulated by 2,4-dichlorophenoxyacetic acid and p-chlorophenoxy acetic acid in L. flavescens at concentrations of 5 and 1 μM respectively. In L. petersonii ssp. root initiation and development was favoured by β-naphthoxyacetic acid (1 μM) and in L. brachyandrum indole butyric acid and α-naphthalene acetic acid (1 μM) were almost equally effective.

    Notes: Summary It was established that anAlnus glutinosa isolate (LDAgp 1) is able to utilize mono- and disaccharides and shows a limited growth ability on arabinose and starch. This contrasts with an isolate fromAlnus viridis (AvcI 1) andComptonia peregrina (CpI1), which apparently lack glycolytic pathway activity. These latter isolates can utilize some tricarboxylic acids in contrast to LDAgp1. Volatile fatty acids or their salts, such as propionic acid and acetate, were utilized by all three isolates. Besides a general ability to utilize inorganic nitrogen sources, some amino acids and urea, selected isolates showed a limitedability to utilize adenine and uracil. A simple, synthetic medium based on propionic acid as the energy source was developed. On this medium some isolates showed growth stimulation in the presence of biotin. The metabolic aspects of the utilization of carbon and nitrogen sources, as well as some ecological consequences are discussed.

    Frankia growth and activity as influenced by water potential (1982)
    Springer
    Plant and soil 69 (1982), S. 293-297 
    Details
    ISSN: 1573-5036
    Keywords: Ecology ; Frankia ; Nitrogen fixation ; Water potential
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Growth responses of Frankia isolates to decreasing water potential were monitored in systems where potentials were controlled by KCl, NaCl and Polyethylene glycol. The highest potential tested was −2 bar (basal medium). The general pattern emerging was that isolates fromAlnus glutinosa, A. viridis andComptonia peregrina showed declining growth at potentials below −2 to −5 bar. AMyrica gale isolate showed declining growth with decreasing potential. All isolates were more sensitive to decreases in potential in a matric controlled than an osmotic controlled system. They all showed approximately 50 percent growth reduction at −5 to −8 bar, and meagre growth at −16 bar after 35 days. The Comptonia isolate was the most vigorous at low potentials. Nitrogen fixation ability was monitored for two isolates. Highest specific activities were observed between −3 and −5 bar for the Myrica isolate and between −5 and −7.5 bar for theA. glutinosa isolate.

    Estimates of Frankia growth under various pH and temperature regimes (1982)
    Springer
    Plant and soil 69 (1982), S. 135-147 
    Details
    ISSN: 1573-5036
    Keywords: Alnus glutinosa ; Frankia growth estimates ; pH ; Temperature
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The growth of Frankia isolates was monitored by dry weight, total protein and total ATP measurements under different temperature and pH regimes. Significant correlations (P〈0.01) were found among all growth measures which meant that similar general conclusions were reached irrespective of the study method involved. The assessment of protein was the method of choice for regular assessments of Frankia growth due to its facility and relatively high sensitivity. The optimum temperature for growth of isolate LDAgp1 and AvcI1 was about 30°C while for CpI1 it lay between 30° and 35°C. No growth was observed at 40°C but some growth was observed at 10°C with isolate CpI1 and LDAgp1 over an extended growth period of 39 days. The range of pH favouring growth lay between 6 and 8. The optimum for LDAgp1 lay between 6.5 and 7, that for AvcI1 and CpI1 is close to 6.5. The pH response was medium dependent. Increases in biomass were observed for some isolates at 4.6 and above 8.0 on some media.
