involucrata into two parts, namely, a southeast and a northwest provenance.
Based on the growth, wood property of the ortets, and rooting abilities of cuttings, 32 Pinus massoniana clones for pulp use were selected from forests of superior provenance, mixed families, and progeny test of seed orchard by two-step selection.
Therefore, provenance of the sedimentary rocks in the Ganzi-Songpan block and Longmen Mountains was the Yangtze craton and/or the Qinling orogen, which evolved on the basis of the Yangtze craton.
It is demonstrated that the mineral field of a proximal polymineral placer is extremely disordered; its mineral assemblages primarily reflect the provenance rock composition and only insignificantly the formation environment of the placer itself.
The provenance of metasediments comprises the following three components: tonalite (dacite) 70%, mafic rocks 20%, and ultramafic rocks 10%.
The L band SFS is constructed by a low power L band amplified spontaneous emission (L-ASE) seed source and a high power erbium-ytterbium co-doped fiber (EYDF) amplifier in double pass configuration.
It is suggested that seed movement would be the potential seed source and play a potentially important role in the process of vegetation restoration of bare alkali-saline patches by enhancing the soil retaining capacity to seed movement.
In the second part of the study, a high percentage of self-seed set was observed during the first flowering of a progeny from a pseudo-self compatible (PSC) seed source.
Six progenies were derived from the PSC seed source.
Chromosome loss or addition did not account for the variation and none of the variant phenotypes was observed in over 400 plants from the parental seed source.
White, translucent, and mucilaginous embryogenic callus was initiated in cultured mature zygotic embryo explants of two different seed sources of slash pine(Pinus elliottii) on several culture media containing auxin and cytokinin.
Response of seed sources to the transfer of populations from their native habitats to the experimental sites has been analysed.
Objectives were to assess the stability of protein profiles for seed sources produced at different locations and in different environments to examine the potential of RP-HPLC to provide genotypic profiles for sorghum.
chromatographic profiles of inbreds, F1, and bulk F2 seed sources can be accurately simulated.
The present experimentation compared the best nutrient medium, temperature, and growth hormones for callus induction and growth of various pine species from different seed sources with their effect on growth of Phytophthora cinnamomi.
