White pine seedlings were treated with triadimefon two weeks prior to natural inoculation with Cronartium ribicola and were observed for two growth seasons. During the second growth season in the greenhouse the incidence of blister rust symptoms was 70.8% for the untreated controls, whereas only 3.8% of the treated seedlings showed symptoms of blister rust. Triadimefon offers effective protection against white pine blister rust infection and would enable the production of bare root seedlings in areas prone to blister rust infection.

In northwestern Algeria, the production of Aleppo pine (Pinus halepensis Mill.) seedlings in four nurseries is hindered by the damping-off disease. Results obtained indicated that Fusarium spp. are commonly found on diseased seedlings, in most containers and bare-root nurseries. Twenty-one isolates of Fusarium, belonging to seven species, were previously isolated from diseased seedlings, and identified based on their morphological and molecular characteristics and their sequences had been deposited in NCBI-Genbank. These isolates were tested for their pathogenicity to local Aleppo pine seeds. The highest inhibition was observed with F. redolens and F. solani, with 75 and 69.3%, respectively. The root growth inhibition of the Aleppo pine seedlings was significantly different for each isolate. The influence of various isolates of Fusarium spp. on seed germination, shoot and root length and vigour index was significantly different. The disease incidence caused by F. redolens and F. solani was 91 and 90%, respectively.

Growth Of Seedlings

Abstract Bare root seedlings of loblolly pine (Pinus taeda L.) with Pisolithus tinctorius (Pers.) Coker and Couch (Pt) ectomycorrhizae were outplanted on typical reforestation sites in the lower coastal plain in Florida and Georgia. After two growing seasons, survival and height growth of seedlings with heavy Pt colonization at planting were not significantly different from control seedlings naturally infected with other ectomycorrhizae. Mycelial inoculum added to the nursery soil resulted in greater Pt colonization of seedlings than basidiospore inoculum applied in an inert coating on encapsulated seed.

Abstract Loblolly (Pinus taeda L.) and slash pine (P. elliottii Engelm.) seedlings can be grown in Number 2 Styroblock containers in timber-truss greenhouses for essentially the same cost per thousand as bare-root seedlings, if construction of a new nursery is contemplated. Because of the time required to expand a bare-root nursery, every additional dollar spent to expand output using a container facility at the existing location is rewarded with $5.90 in present-worth benefits.

Abstract Southern forest nurseries produce 80 percent of the bare-root seedlings grown in the United States (nearly 1.3 billion out of 1.6 billion in 1980). Loblolly pine (Pinus taeda L.) alone accounts for most of the reforestation in this country. Responses by southern nurserymen to a questionnaire were compiled in order to document the practices currently employed to produce southern pine seedlings. In comparison with forest industry nurseries, public nurseries tend to be older and larger, are less mechanized, employ more handweeding, use less cover crops, and produce a greater number of species. The most notable changes occurring in the past 50 years include increased production, a change in the favored species produced, increased chemical pest control, increased mechanical harvesting, and a shift in nursery site selection to sandier soils.

Abstract Bare-root and container-grown shortleaf pine (Pinus echinata Mill.) seedlings with Pisolithus tinctorius and Thelephora terrestris ectomycorrhizae were outplanted on two reforestation sites on the Ouachita National Forest. On the better site, survival and growth of containerized seedlings were better than that of bare-root seedlings. On the poorer site, the reverse was true. Mycorrhizal treatment provided no consistent advantage for survival and growth for containerized seedlings. However, bare-root seedlings with half or more of their ectomycorrhizae formed by P. tinctorius before planting had greater survival and growth on both sites than seedlings with lesser amounts of Pisolithus ectomycorrhizae. The difference in mycorrhizal treatments among containerized and bareroot seedlings are discussed.
