本文对北京地区宿根福禄考组培苗冬季移栽成活率低的问题进行了研究。不同浓度的GA3 处理可显著提高组培苗移栽成活率并促进生长。20μmol·mol- 1的GA3 处理后组培苗移栽成活率由68.18%提高到100%; 与对照相比较, 喷施GA3 的小苗在冬季两个月内株高增至约300% , 功能叶单叶面积增至约200%。各梯度GA3 对宿根福禄考功能叶片光合色素含量以及单位面积的叶片净光合速率影响不显著, 但显著提高了株高和冠幅, 因此移栽苗总的同化产物增加。 相似文献

铁线莲属为毛茛科中具有重要园艺学价值的世界性大属。近年来,国内外专家学者发表了许多铁线莲属分类学、分子系统学和系统基因组学研究文献,使人们对该属的认识与界定发生了巨大的改变。以往分类学上承认的互叶铁线莲属、锡兰莲属等铁线莲亚族中的小属,根据分子系统学研究结果,均应并入铁线莲属中。因此,铁线莲属所包含的植物资源比以前的认识要更加丰富。该研究在以往分类学与分子系统学研究基础上,整理了广义铁线莲属各个属下分类群的野生植物资源状况以及它们的园艺学价值,为我国铁线莲属园艺植物资源开发、利用与保护提供参考。 相似文献

There are frequent anecdotal recommendations for the use of locally produced spent coffee grounds in urban agriculture and gardens, either through direct soil application or after composting with other urban organic wastes. This study investigates the scientific basis for direct application of spent coffee grounds (SCG) and the influence of different: (i) plant pH and nitrogen preferences, (ii) soil types, and (iii) application rates. We specifically consider impacts upon plant growth, soil hydrology and nitrogen transformation processes.We grew five horticultural plants (broccoli, leek, radish, viola and sunflower) in sandy, sandy clay loam and loam soils, with and without SCG and fertilizer amendments. The same horticultural plants were grown in the field with 0, 2.5, 5, 10 and 25% SCG amendment rates. Plant biomass growth was related to soil pH, soil moisture, nitrogen concentration and net mineralization, as was weed growth after harvesting.All horticultural plants grew poorly in response to SCG, regardless of soil type and fertiliser addition. Increasing SCG amendment significantly increased soil water holding capacity, but also decreased horticultural plant growth and subsequent weed growth. There was evidence of nitrate immobilization with SCG amendment. Growth suppression was not explained by soil pH change, or nitrogen availability, so is more likely due to phytotoxic effects.Fresh SCG should not be used as a soil amendment in ‘closed loop’ urban food production systems without consideration of potential growth suppression. Further research is required to determine the optimal composting conditions for SCG and blends with other organic wastes. 相似文献

SummaryHistorical variation in the mineral composition of edible horticultural products was determined from UK and USA food survey data. From these data, it was possible to measure the variation in the mineral composition of edible horticultural products in general, and in edible horticultural products grouped as vegetables, fruits or nuts, in the 1930s and in the 1980s (or later) for both countries. Thus, the hypothesis that the mineral composition of edible horticultural products had altered since the 1930s was tested. The average concentrations of Cu, Mg and Na in the dry matter of vegetables, and the average concentrations of Cu, Fe and K in fruits decreased significantly between the 1930s and the 1980s in the UK. The same hypothesis was tested with comparable data from the USA, whose historical horticultural and consumer practices have paralleled those of the UK. Data from the USA showed that the average Ca, Cu and Fe concentrations in the dry matter of vegetables, and the average concentrations of Cu, Fe and K in fruits had decreased significantly since the 1930s. There were insufficient data to determine if the mineral composition of any single edible horticultural species had altered significantly over time either in the UK or in the USA. The nutritional implications of this study are discussed. Since horticultural products in general, and fruits and nuts in particular, are relatively small contributors of minerals to the average UK diet, historical changes in mineral composition are unlikely to be significant in overall dietary terms. 相似文献
