果实是在前一年的茎上结的。该品种的主要特点是果实大小适中,黑莓味道极佳。由于其生长紧凑(最大高度为2.5米,但在不种植的情况下茎的长度可以达到7米),该品种是小花园和试验种植的理想选择。在半阴或全日照条件下,植株也表现出很高的产量。默顿无刺具有非常高的抗低温能力(最高达零下26摄氏度),但在暴露的地方容易受到严霜的影响。
收获季节从8月中旬持续到9月中旬。浆果重量为3-6克,形状为圆形或略微拉长,颜色为有光泽的黑色。产量约为每株2-4公斤,但如果使用正确的种植和肥料,可以增长到6-8公斤。这个品种有几个品系有不同的花色,从白色到粉红色。
莫顿无刺仍然在伊朗和里海地区进行商业种植,因为它的适应性很强,尽管在西方寒冷的气候中属于中晚熟品种。这些较温暖的地区几乎没有200到600个寒假的时间,那里的冬天通常非常温暖。默顿无刺在英国非常受欢迎,尽管这个品种已经过时了,也主要用于黑莓育种中的无刺来源。
品种的评论 莫顿无刺 (Merton Thornless)
Merton Thornless blackberry plant appears to be the only blackberry of the thornless types to be totally resistant to wilt and root rot as well as other pathogens. Some info on Navaho Summerlong is that it is highly susceptible to root rot like its parent plant Loch Ness from which it's a hybrid cross as the other Navahos. BigandEarly has very high resistance to disease and viruses, but can like all blackberries die when waterlogged for long periods of time, unlike Merton which can regrow new canes from the crown and recover in time.
It's a delightful plant to grow, has a wonderful taste when ripe of the wild blackberry and can fruit anytime from early August onwards in a good summer giving a season of 6 weeks. Yields are moderate- about 3kg on average. It's okay to grow in a patio container and it gives a nice display of white flowers June.
Also it is very forgiving of any soil type and immensely disease resistant with good winter hardiness of minus 20 Celsius. Recommended for those with little space as the canes are short and stout and have moderate vigor. Pests tend leave it alone too! Ideal for both the novice gardener or expert alike.
It will never suffer from frost as it flowers June onwards and has a relatively compact season of usually Mid Aug to end of Sept. I've picked crops of over 10 pounds in some years. It needs a good fertilizer to produce new canes, but even if it produces only one it will still load up with juicy fruit which are about as close to the wild taste as you will ever get.
Merton is only used for breeding new cultivars because of its stable thornless trait and its fruit went out of favour for U.S markets as they are quite soft so didnt ship too well. A true heritage plant from the famous John Innes Institute.
It is a superb cultivar for the home garden and unaffected by pests or disease still makes it a great choice for planting.
