以甜叶菊品种"中山二号"为试材,首先选用叶片、茎段和茎节3种外植体,在添加3种植物激素萘乙酸(1-Naphthaleneacetic acid,NAA)、苄氨基嘌呤(6-Benzylaminopurine,BAP)和激动素(kinetin,KT)不同浓度组合的MS(murashige and skoog)培养基上培养,明确其对愈伤组织诱导和不定芽分化的影响。以叶片作为外植体,使用激素噻苯隆(Nphenyl-N′~(1),2,3-thidiazol-5-yl-urea,TDZ)替换NAA(BAP和KT浓度范围不变),在不同浓度组合的MS培养基上进行愈伤组织、不定芽和丛生芽诱导,以期建立一套快速、有效的甜叶菊再生体系。结果表明:在培养基中TDZ浓度达到3.0mg·L~(1)、BAP 1.0mg·L~(1)和KT0.5mg·L~(1)时,诱导的愈伤组织分化的不定芽最多,且随后形成了大量的丛生芽。丛生芽继代到无添加激素的1/2MS培养基上,能够继续生长,分化成茎叶和根,形成完整植株。该再生体系生产周期短、繁殖系数高,可用于生产上大规模快速繁殖和基因转化研究。 相似文献

Chrysanthemum plants were exposed to 16°C day-temperature, 11°C night-temperature, 13°C soil-temperature, to be indicated as 16/11/13°C, or to 16/11/25°C, 20/16/18°C, or 20/16/25°C, first long day, then short day, (long day = 12-h light period with 3-h night break; short day = 12-h light period) from planting to harvest in controlled environments to study the effects of soil heating on growth and flowering. There were significant, but not substantial, effects of soil heating on leaf area, percent soluble carbohydrate, flower bud diameter, days to visible bud and some other parameters. Two winter cultivars responded similarly, while 2 summer cultivars differed in flowering-response to soil heating. An experiment was also conducted using 16/11/25°C day/night/soil temperatures during long days, short days or throughout the complete growth cycle, with 16/11/13°C day/night/soil temperatures at other times. Soil heating during long days resulted in the highest quality flowers. Soil heating during short days or throughout the growth period resulted in most rapid flowering but decreased flower quality. 相似文献

SummaryPreviously we reported that expression of the Arabidopsis DREB1A gene in chrysanthemum conferred increased tolerance to low-temperature and dehydration stresses, and that transgenic plants in which the DREB1A gene was driven by the abiotic stress-inducible promoter, rd29A, were more tolerant than those plants in which the DREB1A gene was driven by the 35S Cauliflower Mosaic Virus (CaMV) promoter. To understand the molecular basis for this improved tolerance, we isolated 74 DREB1A regulon genes using suppression subtractive hybridisation, then compared their expression patterns in rd29A:DREB1A transgenic plants (rd29A plants) and in 35S:DREB1A transgenic plants (35S plants) under different stress conditions. Our results showed that the increased tolerance to low temperatures and dehydration in rd29A plants was attributed to increased levels of expression of different members of the DREB1A regulon. Levels of expression of 69% or 91% for members of the DREB1A regulon that showed upregulation in rd29A plants were highly correlated with the level of expression of DREB1A in response to low temperature or to dehydration, respectively. These results support the hypothesis that the increased tolerance of rd29A plants to abiotic stresses resulted from elevated expression of the DREB1A regulon. 相似文献

It has become the practice in north-east India to propagate tea vegetatively by means of intemodal cuttings carrying only one leaf. These are prepared by the dissection of leading stems. Extensive experience shows that most of the cuttings will fail if the stems are stored for more than a few hours after being severed from the plant, even if kept moist. If the stems are dissected into cuttings their viability is further reduced. It is usual to set the cuttings in the beds immediately the stems are severed from the plant, and no practicable method has been found by which fresh material can be stored or transported for periods of more than a few hours. Leafless cuttings are of no value. 相似文献

A dynamic model was developed for re-constructing data of shoot leaf area increment in pot chrysanthemum. From specified final areas of individual leaves and time of anthesis of the terminal flower, the model can re-construct dynamic growth of each leaf on side shoots using a modified Richards function. In the model, leaf growth is related to a relative time index ranging from zero to unity, where zero is the start of short day treatment and unity corresponds to anthesis of the terminal flower. Experiments were conducted under greenhouse conditions to collect data for parameter estimation, model verification and model validation. An allometric relationship between leaf length and leaf area was used to estimate leaf area non-destructively from leaf length recordings. When compared with the data used for parameter estimation, the model simulations fitted the data with R2 values ranging from 0.979 to 0.998. In the validation trial the model showed a tendency of over estimation early leaf growth but could explain variations in the data with R2 values ranging from 0.899 to 0.993. 相似文献

A genetic linkage map of chrysanthemum (Chrysanthemum morifolium) was constructed by genotyping 142 F1 progeny of the bi-parental cross ‘Yuhualuoying’ × ‘Aoyunhanxiao’ with a combination of RAPD, ISSR and AFLP markers in a double pseudo-testcross mapping strategy. A total of 567 polymorphic markers, including 153 RAPDs, 61 ISSRs and 353 AFLPs, were used in linkage mapping. 336 of 567 (60%) markers were grouped on the two parental maps, leaving 231 (40%) markers unlinked. In the ‘Yuhualuoying’ linkage map, 210 markers including 116 testcross and 94 intercross markers were placed in 12 major and 32 minor (8 triplets and 24 doublets) linkage groups, covering 1034 cM with an average map distance of 6.2 cM between adjacent markers. In ‘Aoyunhanxiao’ linkage map, 190 markers consisting of 113 testcross and 77 intercross markers were resolved into 9 major and 24 minor linkage groups, with genome coverage of 1095 cM and a mean inter-marker separation of 6.9 cM between adjacent markers. Six pairs of homologous linkage groups were established on the basis of 64 intercross markers shared by the two parental maps. The maps lay a foundation for further quantitative traits loci (QTL) mapping and marker-assisted breeding of chrysanthemum. 相似文献
