以当年生苦水玫瑰半木质化绿枝为扦插材料,采用3因素3水平正交试验和单因素试验设计,分别研究激素种类(NAA、GGR6、ABT1)、激素质量浓度(50、100、200mg/L)、浸泡时间(10、30、60min)和扦插基质对苦水玫瑰扦插生根效果的影响。结果表明:激素种类、激素质量浓度对插穗的生根率、平均根数、平均根长的影响极显著;其生根效果ABT1最优,GGR6次之,NAA最差;激素质量浓度以100mg/L为优水平,而处理时间只对生根率的影响显著。正交试验结果以8号处理最好,即用100mg/L ABT1浸泡插穗10min,其生根率达83.33%,平均根长达8.34cm,平均根数为8.54条/株。扦插基质试验结果以蛭石+珍珠岩(3︰1)为优,但生产中应用河沙+蛭石(1︰1)扦插,成本低,生根效果好。 相似文献

Some varieties of raspberries can readily be propagated from root cuttings. The method is more rapid than the traditional use of root suckers and might be useful in the initial multiplication of raspberry clones. Recommendations are made regarding choice and preparation of parent root material, method of making and planting cuttings, and subsequent management of the plants produced. The behaviour of raspberry root cuttings at various seasons and in different environments is described and discussed. 相似文献

Black currants are readily propagated from single-bud hardwood cuttings approximately i inch long, with the bud at the top and planted vertically. The best part of the shoot from which to take such cuttings is the lower- mid portion (buds 15-22).Optimum rooting is obtained from cuttings planted in January, February and March after dormancy has broken in the field, but by using 24-hour day-length successful rooting can be extended from October to March. The emergence of flowers in March-planted cuttings slightly reduces rooting.Thirteen commercial varieties have been propagated successfully by this method.Suitable softwood and semi- hardwood cuttings are available when the current season's shoots are 12 nodes or more in length, i.e. normally in late April. When these are planted in a propagation frame with soil heating, good rooting is obtained from April to June provided the subtending leaf is retained during the rooting period.Twenty-four-hour day-length increases the rooting of cuttings planted in July; lack of rooting after July is attributed to early leaf abscission, the initiation of flowers and the onset of dormancy. 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

稀土对番茄扦插生根的影响 总被引:1,自引:0,他引:1
稀土是镧系元素及其性质相近的钪和钇等 17种金属元素的总称,对改善植物的生理代谢、生长、繁殖、品质以及产量具有积极的作用〔1, 2〕。番茄用侧枝扦插繁殖,对缩短秋延后番茄育苗时间,以及节约种子、降低成本、对稀有材料的保存利用具有实际意义。有研究S3307对番茄生根具有促进作用〔3〕,但稀土对番茄扦插生根的作用未见报道,笔者就此进行研究,以期为稀土在番茄扦插育苗中的应用提供依据。1 材料与方法1. 1 材料 供试番茄为花溪红,供试稀土为河南商丘稀土微肥厂生产的常乐—益植素。1. 2 方法 2003年 1月 15日于温室电热温床中… 相似文献
