【目的】江南园林假山是园林遗产的重要组分。植物根劈现象广泛存在于各遗产园林之中,严重威胁着假山遗产的长久保存与发展。作为假山安全与保护的影响因素,将植物根劈现象纳入假山预防性保护体系,能够为假山预防性保护体系的构建和完善进而有效开展园林遗产保护提供依据。【方法】以南京瞻园为例,对假山受植物根劈的作用机理进行量化分析,总结南京瞻园假山现状中的问题树种,提出并验证了5个与植物根劈作用显著相关的植物变量,建立了有关植物根劈的裂缝面积回归预测模型。【结果】通过分析植物根劈现象的现状特征,认为直根系、深根系树种更容易导致假山裂缝问题,南京瞻园的此类树种中,朴树、女贞的根劈作用对假山的影响最为显著,枇杷、龙爪槐、广玉兰、木瓜的根劈作用次之。通过相关性分析发现,裂隙内根长、根径、植物冠幅、树高、基径是根劈作用的5种主要影响因子,与根劈作用产生的裂缝面积显著相关。其中,裂隙内根长、裂隙内根径与产生的裂隙面积呈正相关。通过多元回归性分析,初步构建假山裂缝面积预测模型,并设置相应的假山裂缝变化预警阈值,认为裂隙内根径不变而根长变化值超过11.25 cm时,即应考虑抑制单条根系的发育。【结论】植物根劈作用加剧了假山石体表面裂隙的发育和扩展,甚至有可能导致石体的断裂和山体的崩塌,严重威胁着假山遗产的长久保存与发展。根据量化分析的结果进一步筛选环境变量,划分监测等级并明确预警指标,可以提高假山遗产保护的预知能力和定量判断能力,达到及时预防、削弱植物根劈作用力并完善假山预防性保护体系的目的,为古典园林假山遗产的预防性保护工作提供参考。

Three 2x clones with 2n pollen production, BPH322,BPH325 and W5295,7, were each mated with three 4x cultivars, Raritan, Superior and Trent, in an incomplete diallel cross design. Estimates of various heritability for tuber yield per plant are that h2m is 3720%,h2f 1630%,h2mf 2330%,h2B 7670% and h2N 5340%. Estimates of general combining ability(GCA) and specific combining ability(SCA) are 6960% and 3030%,respectively. The results suggest that additive effect of genes for tuber yield is obvious. The 2n pollen producing diploid hybrids have good breeding values for yield ,earliness and starch content.

Neo-tuberosum derived from S. tuberosum ssp. andigena is a very important genetic resource in potato breeding. In 1970′s, Neo-tuberosum clones were introduced into China and improving programs were started at that time. The improved clones of it were obtained through recurrent selection in different latitudes of China. According to obvious heterosis appeared in crossing with common potato varieties, Neo-tuberosum would be good parents for breeding and true potato seed (TPS) production. Dihaploid of Neo-tuberosum were obtained by parthenogenesis, and its male fertility was recovered by crossing with S. phureja as male parents. Using acceptable improved Neo-tuberosum clones as a parent, the tuber yield of TPS population was increased greatly.
