Study On The Ornamental Evaluation Of Fourteen Cerasus Serrulata Cultivars And The Application In Landscape

C_erasus serrulata is one of the early spring world famous flowering plants blong to Rosaceaefamily C_erasus genus.There are many varieties are rich in resources, have broad development andapplication prospect. The current research mainly focuses on resources investigation, varietiesclassification, introduction and domestication, culture and breeding, however, studies on horticulturecharacteristics and landscape application mode of leaded varieties is involved little everywhere. Theplant is still short of complete theoretical guidance and methods, disadvantages of simplex variety anddisposition form, and lag behind in the level of application.The morphological parameter related to ornamental value of14cultivars ware studied in the springof2010,2011and2012, and then Analytic Hierarchy Process was used to evaluate ornamentalcharacteristics based on the research above. On the basis of studies mentioned above, landscapeapplication modes were developed with the using of field investigation and case analysis. C_onclusionsof each research were listed as follow:1. Analytic Hierarchy Process （AHP） was used to establish the integrated evaluation system forCerasus serrulata cultivars on ornamental characteristics. The system was subdivided into target level,criterion level and index level. The target level （A） refers to the integrated assessment of ornamentalcharacteristics for Cerasus serrulata. The criterion level （C） was founded on flower （C₁）, plant habit（C₂）, bud （C₃）, branches （C₄）, leaf （C₅） and rarity （C₆）. The index level （P） refers to specific indicatorsrelated to ornamental characteristics. The sort orders on factor weights for the criterion level and indexlevel are C₁＞C₂＞C₅＞C₆＞C₄＞C₃and P₁₅＞P₃₂＞P₁＞P₇＞P₁₆＞P₂＞P₂₂＞P₉＞P₈＞P₁₀＞P₂₆＞P₃＞P₄＞P₂₄＞P₅＞P₁₇＞P₂₇＞P₂₈＞P₂₁＞P₂₉＞P₁₈＞P₂₃＞P₆＞P₁₁＞P₂₀＞P₁₄＞P₁₃＞P₁₂＞P₂₅＞P₃₀=P₃₁＞P19correspondingly. The flower （C₁） with largest weight in the criterion level is a most important andbasic property in ornamental evaluation for C_erasus serrulata cultivars, and followed by plant habit （C₂）which greatly affect the ornamental value of C_erasus serrulata and other garden plants. The bud （C₃）plays a smallest role in the ornamental assessment. On the index level, tree-shape (P₁₅) with a largestweight in the index level is a major criterion affecting the ornamental evaluation for Cerasus serrulatacultivars, and followed by rarity (P₃₂), flower diameter （P₁） and flower color （P₇）, however, buds shape(P₁₉), leaf apex shape (P₃₀) and leaf base shape (P₃₁) are three factors with relative small influence onthe ornamental evaluation.2. The integrated assessment of ornamental characteristics for C_erasus serrulata cultivars. Theevaluation scores on ornamental basis for Cerasus serrulata cultivars could be arranged as highest（Ⅰ）,higher（Ⅱ）, high（Ⅲ）, normal（Ⅳ） and low （Ⅴ） for5grades. The corresponding sort order for14majorcultivars is C_erasus jamasakura ‘Haguiensis’＞Cerasus incise ‘Yamadei’＞Cerasus subhirtella var.Pendula ‘Plena-rosea’＞C_erasus serrulata var. lannesiana ‘Sekiyama’＞Cerasus serrulata var.lannesiana ‘Hisakura’＞C_erasus sargentii ‘Rehder’＞C_erasus serrulata var. lannesiana ‘Albo-rosea’＞Cerasus yedoensis ‘Yedoensis’＞Cerasus serrulata var. lannesiana ‘Yaebeni-Oshima’＞Cerasus serrulata var. lannesiana ‘Shiratama’＞Cerasus yedoensis×Cerasus campanulata ‘Yangguang’＞Cerasus serrulata var. lannesiana ‘Sendai-shidare’＞Cerasus serrulata var. lannesiana ‘Caudata’＞Cerasus subhirtella ‘Subhirtella’. Among them Cerasus jamasakura ‘Haguiensis’, Cerasus incise‘Yamadei’, Cerasus subhirtella var. pendula ‘Plena-rosea’, Cerasus serrulata var. lannesiana‘Sekiyama’, Cerasus serrulata var. lannesiana ‘Hisakura’, Cerasus serrulata var. lannesiana‘Albo-rosea’, Cerasus sargentii ‘Rehder’, could be selected as the superior cultivars for thepopularization and application of green space.3. Studies on the landscape application modes of Cerasus serrulata.Through field investigation andcase analysis of Hangzhou west lake scenic area, put forward landscape application modes, includingcourtyard houses configuration mode, grassland margin configuration mode, garden entrance or roadcorner configuration mode, waterscape space configuration mode and theme park mode, for purposes ofguidance.
