With the purpose of obtaining apple plants with reduced vigour but deep and expanded root apparatus, more adapted for establishment of apple orchards in dry, windy areas and higher altitudes, different interstem/rootstock combinations were compared, using seedling as rootstock and, alternatively, two weak interstocks (M.9 and M.27). For all treatments the plants were grafted at two height from soil (10 and 20 cm), interposing interstock 10 or 20 cm long. Plants with interstock showed lower vegetative growth in comparison with control plants with a reduction of 80% (M.27) and of 50% (M.9) of canopy growth. Moreover, use of interstock determined, as compared with the control plants, an increase of fruit production and average fruit weight. It was noted that increasing the interstock length, caused reduction of plants vigour and fruit production. The results showed that, the combination “Annurca Rossa del Sud”/M.9 (10 cm long)/seedling rootstock (20 cm high) was the most efficient for productivity, early maturing and plant vigour control.  相似文献

An in vitro plant regeneration protocol for pansy (Viola wittrockiana) cultivar ‘Caidie’ from petioles was established as following: callus induction on a half-strength MS medium supplemented with 0.45 μmol l−1 2,4-d plus 8.9 μmol l−1 BA, callus subculture on medium F (1/2MS with 4.5 μmol l−1 2,4-d, 2.7 μmol l−1 NAA and 0.44 μmol l−1 BA) and then on medium T (1/2MS with 4.5 μmol l−1 2,4-d, 2.7 μmol l−1 NAA and 2.2 μmol l−1 BA), shoot regeneration on medium D3 (MS media supplemented with 2.9 μmol l−1GA3, 23.6 μmol l−1 AgNO3, 0.02% active charcoal and 4.5 μmol l−1 TDZ), shoot multiplication on medium M (half-strength MS medium containing NAA 1.1 μmol l−1, TDZ 9.1 μmol l−1 and GA3 8.7 μmol l−1), and then shoot elongation and rooting on medium R (MS medium supplemented with 1.1 μmol l−1 NAA and 1.1 μmol l−1 BA). Subculture on appropriate medium was found to be important for successful shoot regeneration.  相似文献

The influence of 24 h mean air temperature (18.3, 20.6, 23.9 and 25.8 °C) and photosynthetic photon flux (PPF; 0.6, 2.1, 3.7 and 4.7 mol m−2 d−1) on the growth cycles of vegetative growth in Ilex × meserveae (‘Blue Princess’ S.Y. Hu) was investigated. Plants propagated from top cuttings were grown in greenhouse compartments. The number of unfolded leaves was recorded continuously throughout the experiment. A modified sine function was fitted to collected data and the values for the amplitude and frequency of the growth curves were analysed. The sine function was tested as a method to evaluate the influence of climate on periodically flushing species. Both amplitude and frequency were significantly influenced by air temperature and PPF. The highest frequency of flushing was found at 23.9 °C and 3.7 mol m−2 d−1. The function resulted generally in a good fit to collected data with R2 values above 0.9. Growth curves of all individual plants were categorised with respect to their growth pattern as poor synchronisation within the treatments did not allow analysis of the mean values of the growth curves.  相似文献

A mutant of Musa spp. ‘Williams’ was isolated by screening the plants from tissue culture and rapid propagation. We studied the morphological characteristics of the fruit epidermis by scanning electron microscopy (SEM). The results showed that the pericarp of mutant was covered with trichomes. These trichomes were pointless and the length of the trichomes ranges from 0.02 to 0.37 mm. However, this kind of trichome was not observed on the pericarp of the wild type.  相似文献

AIM: To clone human β-globin gene carrying a thalassemic mutation IVS II654(C→T) and establish a eukaryotic expression system for high-level expression of human β IVS II654 gene in mouse erythroleukaemia(MEL) cells. METHODS: The fragments of human β 654 gene isolated from the β thalassemia patients homozygous for the β 654 mutation were amplified by PCR, and cloned to plasmid pBGT51. Then, the human β LCR and β 654 gene were subcloned from plasmid pBGT51 to the stable mammalian expression vector pcDNA3. 1+ together, and the MEL cells were transfected with this vector using commercially available cationic lipid FuGENE6. The MEL cells were induced for further maturation by DMSO and the expression of human β 654 gene in the MEL cells was identified by RT-PCR. RESULTS: A mammalian expression system of human β thalassemic mutation βIVS II654(C→T) was established. CONCLUSION: The level and the reliability of expression of human β 654 gene in the MEL cells in vitro are similar to that in vivo in human body. This may be a valuable gene therapy model for human β thalassemic mutation βIVS II654(C→T).  相似文献

Context

In a global context of erosion of biodiversity, the current environmental policy in Europe is oriented towards the creation and the preservation of ecological networks for wildlife. However, most of the management guidelines arose from a structural landscape diagnostic without truly taking into consideration species’ needs.

Objectives

We tested whether and how landscape elements influence the functional connectivity of landscapes for a forest specialist species, the European pine marten (Martes martes), in Northeastern France.

Methods

We collected pine marten scats and tissues from 13 evenly distributed study sites across the whole study area in order to test several types of barriers such as highways, waterways, and open agricultural fields. We crossed the results of several methods: spatial autocorrelation analysis, causal modelling framework, and clustering methods.

Results

The study indicates significant genetic differentiation among the sampling sites. A signal of isolation by distance was detected but disappeared after partialling out landscape or barrier resistance. The only model that was fully supported by causal modelling was the one identifying waterways as the main driver of genetic differentiation. Moreover, clustering analyses indicated the presence of genetic clusters, suggesting that pine marten spatial genetic pattern could be explained by the presence of waterways but also by their reluctance to cross open fields.

Conclusions

The current ecological network could thus be improved by increasing permeability of waterways, in particular navigation canals, and by maintaining and restoring forested corridors in agricultural plains.

ISSR molecular marker was used to investigate genetic diversity of ‘Dare Gazi’ genotypes of Mashhad Esteghlal orchard and its relationship with other commercial and native cultivars of pear. Among ‘Dare Gazi’ genotypes of Mashhad Esteghlal orchard 23 genotypes were selected base on difference in tree vigor, leaf color, shape and color of fruit and also 33 other commercial and native pear cultivars from Esteghlal orchard and other Mashhad commercial orchards were studied. A total number of 230 DNA fragments were obtained using 11 primers of which 225 were polymorphic. On average, each primer produced 20.9 bands. Dice similarity coefficient ranged from 0.27 (between ‘Dom Kaj’ and Asian pear) to 1 (between ‘Dare Gazi’ 1 and 2 genotypes). Sample cluster dendrogram indicated that 56 genotypes were divided into 12 distinct clusters. The dendogram generated on the principle of Unweight Pair Wise Method using Arithmetic Average (UPGMA) was constructed by Dice coefficient and the genotypes were grouped into 12 clusters. ‘Dare Gazi’ genotypes did not show 100% similarity due to seed propagation or mutation, as ‘Dare Gazi’ 3 and 18 genotypes had the lowest similarity coefficient (0.64). Asian pears were placed in a separate group from European pears. And ‘Dare Gazi’ genotypes from different orchards were grouped separately, but all of them are called as ‘Dare Gazi’ pear for convenience. ISSR molecular marker can well identify the genetic variability among genotypes and cultivars and found suitable for grouping them.  相似文献

Invasive alien species can pose a severe threat to biodiversity and stability of the ecosystems they invade. Predicting distribution patterns of invasive species in regions outside their native range is a fundamental component of early warning systems. Crofton weed (Eupatorium adenophorum Spreng.) was first discovered in the Yunnan Province of China around the 1940s. The well-documented invasion history of this plant species provided the opportunity for us to examine the spatiotemporal patterns of biological invasion by crofton weed. Using the datasets documenting 441 known localities invaded by crofton weed in China over the past 50 years and 23 environmental variables generated by the genetic algorithm for rule-set production (GARP) model, we tested the predictability of crofton weed distribution with a high degree of accuracy. Both the Kappa statistics and the receiver–operator characteristic (ROC) analysis indicated that it is possible to predict the geographical spread of crofton weed in China. Precipitation in the coldest quarter of the year, extremely low air temperature, and maximum annual air temperature strongly influenced the predictions. Our results indicate that crofton weed may break out in Yungui Plateau, Sichuan Basin, southeastern Coastlands, Hainan Island, and Taiwan although currently it is either absent or has only recently been recorded in these regions. Redundancy analysis (RDA) ordination results demonstrated that temperature and precipitation play an important role in confining the spread of crofton weed. Over the past 20 years, crofton weed has spread from subtropical areas with higher annual mean temperature and lower climatic fluctuations to much cooler and dryer areas at higher altitudes. The distribution of crofton weed was restricted mainly to regions with mean annual air temperature ranging from 10 to 22°C and annual precipitation from 800 to 2000 mm. Our results could help in developing and implementing early detection measures to minimize the ecological impacts of crofton weed invasion in China.  相似文献
