  • The concept of natural grouping of plant designated as the "Amentiferous" is no longer given serious credence, and many of the families included in this grouping have been dispersed in diverse order. Because a review of taxonomic treatments of amentiferous taxa reveals diverse classifications, it has become necessary to investigate new characteristics and attempt to determine the significance of these characteristics in terms of amentiferous taxonomy. Protein analyses by isoelectrofocusing(IEF) and rocket immunoelectrophoresis(RIE) have proved to be useful in the delicitation of Quercus taxa using pollen extracts from selected taxa. When Quercus pollen extracts were separated by electrophoresis based on their isoelectric points in a stable pH gradient and substrates for estrase activity were stained, ten bands were revealed between pH 5-14. Within Lepidobalanus grouping, a great diversity in the pollen protein zymograms was observed with some segregation corresponding to the designated taxonomic sections. Two taxa of Cyclobalanopsis produced a zymogram that is somewhat similar to taxa included within the section Prinus of Lepidobalanus, and less similar to taxa within the section Cerris of the same subgenus. Three tested taxa of the Cerris are in the similar zymogram each other, being segregable from the taxa of Prinus. Quantitative and qualitative analyses for serological relationships within and among th Quercus were also employed. To calculate the degree of protein similarity, total rocket heights obtained from RIE provided an index of serological correspondence(SC). It is reconfirmed that the Quercus is distantly separated from the Fagus according to SC. Comparative data from rocket number and SC in the tested taxa of Quercus also indicate that Lepidobalanus is separable from Cyclobalanopsis. Within the Lepidobalanus Q. acutissima and Q. acutissima x variabilis are almost homogeneors and distinguishable from the other tested taxa of same subgenus. Although the number of taxa tested has been limited, the overall serological evidence best reflects the classification proposed by Redher(1940) and Melchior (1964), having the genus Quercus subdivided into three subgunera: Erythrobalanus, Lepidobalanus, and Cyclobalanopsis.alanopsis.

  • The purpose of this study is to offer raw data regarding landscape plantings of traditional cultural heritages by surveying and analysing the actual flora and landscape planting species distributed in Donggung Palace and Wolji Pond in Gyeongju, Korea. The results are as follows. The flora were summarized as 149 taxa including 65 families, 117 genera, 134 species, 1 subspecies, 10 varieties and 4 forms. The naturalized plants were of 18 taxa including Rumex crispus, Trifolium repens, Ailanthus altissima, Veronica persica, Senecio vulgaris, Festuca myuros and the like. Invasive species included Rumex acetosella. As a result of the analysis of chronological changes in landscape planting species, 23 taxa were planted in 1979, whereas 48 taxa were planted in 2014. Therefore, the number of these species increased by 25 taxa. The landscape planting species were of 48 taxa including 6 taxa of evergreen trees, 2 taxa of evergreen shrubs, 27 taxa of deciduous trees, 12 taxa of deciduous shrubs and 1 taxa of other. In present conditions by sections, Section A was 25 taxa, 15 taxa of Section B, 13 taxa of Section C and 29 taxa of Section D. The species planted in common were 4 taxa including Pinus densiflora, Acer palmatum, Euonymus alatus and Rhododendron yedoense for. poukhanense. The problems in the present conditions of landscape planting were volunteer species, the occurrence of scrub and vines and the spread of invasive alien plants. To restore and improve the planting landscape and facilitate tree growth, scrub, volunteer species and invasive alien plants must be removed.
