Rooting Of Cuttings

Cuttings from older pines rooted more abundantly and rapidly in a growth chamber than in a greenhouse. Numerous rooting powder formulations were tested, and those containing auxins, sucrose, a fungicide, and a growth retardant outperformed those lacking one or more of these components. Best treatment combinations gave 83% rooting of cuttings from 13-year-old shortleaf pine (Pinusechinata Mill.) in 12 weeks, 100% rooting of cuttings from 12-year-old Japanese black pine (P. thunbergiana Franco) in 8 weeks, and 100% rooting of cuttings from 1-year-old slash pine (P. elliottii var. elliottii Engelm.) in 6 weeks. The most effective powder contained 1% each of indolebutyric acid, 1-phenyl-3-methyl-5-pyrazolone, and N-dimethylaminosuccinamic acid, plus 10% each of powdered sucrose and captan.

Mycorrhizal Roots

Mycorrhizal status, soil and foliar nutrient status, and production histories were determined for Japanese black pine (Pinus thunbergiana Franco.) and dwarf Mugo pine (Pinus mugo Turra ‘mugo’) in 4 Long Island, New York nurseries. All pines sampled were mycorrhizal. No significant effect of age on percentage mycorrhizal roots was observed between 2-,3- and 5-year-old Japanese black pine. The extent of mycorrhizal formation with Mugo pine could not be correlated with differences in soil or foliar nutrient status among 3 field nurseries. However, field grown Mugo pine had approximately 20% more mycorrhizal roots (70%) than container grown plants (50%). A controlled greenhouse study of Mugo pine inoculated with the ectomycorrhizal fungus Pisolithus tinctorius (Pers. Coker and Couch) showed decreased mycorrhizal levels with increased N, suggesting that differences in mycorrhizal intensity between field and container grown nursery stock may have been related to differences in fertility.

Abstract Greenwood cuttings from greenhouse-produced tamarack seedlings and 3- to 10-year-old tamarack wildlings transplanted from natural stands in north-western Ontario were rooted under mist in peat-vermiculite. Eighty-five percent of cuttings from seedlings rooted; treatment with indolebutyric acid increased number of roots per cutting, but not rooting percent. At 6 weeks after planting, rooting of cuttings from wildlings averaged 66%, and at 12 weeks, 91%. Twelve-week rooting percent of cuttings from individual ortets ranged from 12 to 100, but cuttings from the majority of ortets exhibited 100% rooting. Nearly all rooted cuttings survived overwintering outdoors and initiated normal shoot growth after forcing in mid-winter. The described propagation system is recommended for production of container stock for tamarack plantations. North. J. Appl. For. 3:91-93, Sept. 1986.

Root Growth And Development

Association between auxins and plant growth-promoting bacteria can stimulate root growth and development of fruit crop nursery plants, and can be a promising biological alternative to increase the rooting of cuttings. The objective of this study was to assess the viability of producing ‘Powderblue’ blueberry nursery plants from cuttings using different doses of indolebutyric acid (IBA) in association with Azospirillum brasilense. The following treatments were tested: 0 (control); 500 mg L−1 of IBA; 1000 mg L−1 of IBA; A. brasilense; 500 mg L−1 of IBA + A. brasilense; and 1000 mg L−1 of IBA + A. brasilense. The experimental design was completely randomized, with six treatments and four replicates, and each plot (box) consisted of 10 cuttings. The boxes were arranged in a mist chamber with an intermittent regimen controlled by a timer and solenoid valve. After 90 days, the following variables were assessed: rooted cuttings; survival of cuttings; foliar retention; sprouting; cuttings with callus; root dry mass per cutting; number of roots per cutting; and root length. It was observed that the application of IBA with the A. brasilense rhizobacteria increased the number of roots of ‘Powderblue’ blueberry cuttings, while the treatments with IBA alone and IBA 1000 mg L−1 + A. brasilense increased the root length of cuttings. However, treatments with IBA and A. brasilense had no impact on % rooted cuttings and % survival of cuttings.
