Micropropagation of an endangered species Pinus armandii var. Amamiana

Katsuaki Ishii , Yoshihisa Hosoi, EmilioMaruyama [2008]

For micropropagation via organ culture, mature embryos were excised from the seeds of Pinus armandii. Franch. var. amamiana (Koidz.) Hatusima, an endangered species only inhabiting the south west islands of Japan. Adventitious buds were induced on the surface of the embryo on 1/2 DCR medium containing BAP, and they grew shoots after subculturing to medium containing activated charcoal or a low ...

In natural pine populations, a mixed mating system is typical, characterized by the proportions of selfed and outcrossed seeds. Swiss stone pine(Pinus cembra L.) is one of the least studied European conifers in this respect. The mating system of six polymorphic allozyme loci were studied in haploid megagametophytes and diploid open-pollinated embryos in two stands located in the East Carpathia ...

Genetic structure of sympatric Pinus sibirica Du Tour and P. pumila (Pall.) Regel populations and putative interspecific hybrids between them was analyzed in the Baikal Lake region (Barguzin Biosphere Natural Reserve, Davsha River basin) by means of 31 allozyme loci controlling 18 enzyme systems. Several alleles at loci Adh-1, Fest-2, Lap-3, Pgi-1, Sod-3 and Skdh-1 were diagnostic for P. sibir ...

In the Baikal Region, there is no phenological isolation between Siberian stone pine (P. sibirica Du Tour) and Siberian dwarf stone pine (P. pumila (Pall.) Regel) since the timing of their 'flowering' coincides. Morphologically intermediate individuals, supposedly natural hybrids,occur not very often. In the west half of Stanovoye upland area four regions were investigated: Barguzinskiy, Baika ...

Dorena Genetic Resource Center (DGRC) has used artificial inoculation trials to evaluate progenies of thousands of Pinus monticola and P. lambertiana selections from Oregon and Washington for resistance to white pine blister rust caused by Cronartium ribicola. In addition, early results are now available for P. albicaulis and P. strobiformis. DGRC has also recently evaluated seed orchard proge ...

This field trial evaluates white pine blister rust resistance of 49 families of Pinus monticola from Oregon and Washington. The Optical site had 93% of the trees infected six years after planting, but rust mortality is currently low. Families ranged between 31 to 100 percent infected and the number of stem symptoms ranged between three and eighteen. Families with R-gene resistance (HR) from th ...

Pinus wallichiana A.B. Jacks is an important component of the middle and high altitude Himalayan forests having large natural distribution ranging between 260 to 360 N latitude and 690 to 750 E longitudes. It is commonly known as Himalayan blue pine or blue pine, being indigenous to Himalayan Mountain regions and because of its bluish or grayish-green leaves. It is a five needle pine which gai ...

A map with the distribution of the Swiss stone pine (Pinus cembra L.) in Romania was never made. However, long time ago, some poor or confused data collected from the Romanian Carpathians were inserted in a compiled at European level map; but this map do not reflects the species real geographic distribution in the Romanian Carpathians. Consequently, a initiative to build up a not to far from r ...

The author presents a short overview concerning eastern white pine (Pinus strobus L.) introduction in different European countries, including the period of early extension in forest culture until the first blister rust crisis occurred. The species rehabilitation at the European level and the new extension between 1927 and 1972 years period in different countries, particularly in Romania, was p ...

Siberian stone pine (Pinus sibirica Du Tour) is one of the main forest-forming tree species in boreal forests of Eurasia. Large edible seeds of this species have an important resource value because of their high nutritious properties. Development of approaches to establishment of early cone producing Siberian stone pine stands including utilization of corresponding genetic background is one of ...
