葡萄从扦插育苗、栽植到结果，一般要3年时间，在加强管理的条件下，进行催根育苗，定植第2年即可结果。选择健壮、冬芽饱满的枝条，截成2～3芽的枝段，上端在芽上3cm处平剪，下端在芽下5cm处斜剪，用生根剂浸泡插穗下端后，将其每50～100条捆扎成1捆。先将生根床上的土挖深30～40cm，把成捆的插穗倒置排在生根床内，上面用细沙覆盖至不露插穗，然后洒水，插穗间的空隙用沙充实。在生根床上搭2层拱棚。这样插条上部温度高而下部低，使生根床上面的温度保持在25％，20天左右即可生根，而下端因温度低故不能发芽。 相似文献

以无花果‘波姬红’1年生枝条为试材，探索基质配比及插条部位对无花果扦插生根效果的影响。结果表明：基质种类对无花果扦插生根有显著影响。其中，珍珠岩基质生根效果最佳，与园土（黄沙+驴粪）相比，萌芽率高52.22个百分点，生根率高46.66个百分点，生根数增多15.33条，平均根长增长3.26cm，最长增长6.84cm，根基部增粗0.07cm，根系效果指数提高14.62倍，根鲜重增重1.70mg，新枝鲜重增重1.97mg，根冠比提高0.55。珍珠岩+草炭（2︰1）和蛭石+草炭（2︰1）与珍珠岩、珍珠岩+草炭（2︰1）相比生根率和其他生根指标不占优势。5种基质处理的生根效果表现为：珍珠岩>珍珠岩+草炭（2︰1）>蛭石+草炭（2︰1）>珍珠岩+草炭（2︰1）>园土（黄沙+驴粪）。插条部位对无花果扦插生根效果存在显著的影响。插条基部的生根效果优于中、顶部的生根效果。因此，无花果扦插时应选择基部的插穗，插穗粗2.0～2.2cm能够取得最佳扦插生根效果。 相似文献

Either before or after curing their cut surfaces for 5 days, 7 cm- and 15-cm-long decapitated Hylocereus trigonus cuttings were treated by soaking their apical or basal ends in benzyladenine (BA) solution. They were then planted and grown in a greenhouse.For the 7 cm-long cuttings, BA (25–100 mg l?1) applied to the apical ends for 24 h increased the ratio of cuttings with sprouted buds to 64–100%, the number of sprouted buds to 1.9–3.1 and of shoots to 1.6–2.8, and the shoot length to 35–60 mm, compared to the water control which showed 13%, 1.0, 1.0 and 12.5 mm, respectively. Soaking the basal part had only a small effect.Naphthylacetic acid (NAA) applied to the basal ends of cuttings immediately after cutting increased the number of sprouted buds and shoots by inducing early rooting. The number and length of BA-induced axillary shoots in the longer cuttings was greater than those in the shorter ones.In the 15-cm-long cuttings, increasing the soaking time from 5 min to 24 h resulted in a greater promotive effect of BA on shoot formation. BA applied before curing showed the same effect as that given after curing but caused necrosis of the tissue just under the cut surface. Enlarging the area soaked in BA solution from 5 cm to 10 cm decreased the number of sprouting buds and shoots. 相似文献

The growth of roots and shoots of cuttings taken from nodes 3 to 9 on the parent stem, counting from the apex, have been compared. Comparisons also included dry weight of parts of the cuttings and leaf areas.The number of cuttings with roots was unaffected by node origin; the weight of roots was similarly unaffected with the exception of one doubtful case.Shoot growth, on the contrary, was found to be much more advanced in cuttings from older nodes, presumably because the buds were more highly developed. The cutting buds produced the flush-type growth and leaf forms typical of a mature tea bush.The effect of node position on dry weights of cuttings was irregular. The greater loss of original leaves among cuttings from older nodes appeared to counteract the expected greater dry weight of these cuttings. 相似文献

The appearance and development of buds on leaf cuttings of Begonia × hiemalis in long and short days
Bud initiation in leaf cuttings of Rieger begonia ‘Schwabenland Red’ was not affected by daylength. Approximately 30 buds per cutting were observed 13 weeks after insertion. Of these, an average of 8.2 developed into fully grown shoots in long days as opposed to 1.9 in short days. Competition between buds was apparent in both treatments, its effect being greatest on buds with fewer than 4 leaf primordia. 相似文献

In one-node stem cuttings of Eucalyptus granáis the absence of leaves was fatal. The optimum leaf area per leaf for rooting was 2-5 cm2, and in this range rooting was higher in one-leaf than in two-leaf cuttings. Axillary shoots started to develop soon after the cuttings were set and their growth was promoted by the presence of the subtending leaf. Thus, in one-leaf cuttings the shoot in the leafy axil grew, at the expense of the shoot in the defoliated axil, while in two-leaf cuttings the shoot in the upper (sub-opposite) axil tended to grow more quickly. Axillary shoots were also vigorous in cuttings from decapitated and disbudded mother plants. Rapid shoot growth was associated with low rates of abscission of the subtending leaf and relatively high rooting ability. Removing axillary shoots from cuttings accelerated leaf abscission and reduced rooting. The stem of the cutting often swelled and discoloured from the base, apparently due to the demand of the cutting for water. Additional leaf wounds had no effect on rooting (but increased mortality), while immersing cuttings in water before setting, or leaving them in a loose heap on the propagation bench, promoted rooting. 相似文献

Root formation in chrysanthemum (Dendranthemum grandiflora (Ramat.) Kitamura) cuttings was reduced as flowers developed on stock plants. This effect was shown for all ten cultivars evaluated in this study. Not all cultivars were affected equally by the presence of flower buds on cuttings. There was no relationship (r2 = 0.06) between root formation in vegetative cuttings and the ability for a cultivar to root from flowering cuttings. IBA (1 mM) could partially overcome the negative effect of flowering on root formation, but cuttings taken after the flower buds had fully opened failed to root even after auxin treatment. Removing buds from cuttings or continually removing flower buds during stock plant growth reduced rooting compared to cuttings with flower buds intact. Furthermore, cuttings taken from the top three nodes of the stock plant containing flower buds rooted comparably to cuttings taken from the lower stem section that contained only vegetative buds. The negative influence of flowering on root formation appears to be due to the photoperiodic induction of the flowering stimulus rather than a direct competition for resources between flowers and developing roots. 相似文献
