Safety & Hazards

Although no specific information has been seen, the seed and other parts of the plant (but not the fruit) are likely to contain cyanogenic glycosides. When injested, these compounds break down in the digestive tract to release cyanide. Used in small quantities in both traditional and conventional medicine, this exceedingly poisonous compound has been shown to stimulate respiration, improve digestion, and promote a sense of well-being[1]. It is also claimed by some to be of benefit in the treatment of cancer - though this claim has been largely refuted. In larger concentrations, however, cyanide can cause gasping, weakness, excitement, pupil dilation, spasms, convulsions, coma and respiratory failure leading to death[2]. The levels of toxin can be detected by the level of bitterness:- sweet almonds, for example, contain only very low levels of it and are safe to eat in quantity, whilst bitter almonds (which are used as a flavouring in foods such as marzipan) contain much higher levels and should only be eaten in very small quantities. Great caution should be employed if the taste is moderately to very bitter[PFAF].

Cultivation Details

Growth—

The primary climatic requirements for the production of good quality fruit are warm summer temperatures, relative freedom from spring frosts, reasonable protection from the wind (especially cold north and east winds) and an evenly distributed rainfall of about 600 - 800mm per annum[3]. Good apple production has been achieved as far north as 65°, whilst about 1,000 hours of winter temperatures below 7°c are necessary to initiate flower production[4]. However good quality apples can still be produced in other areas with careful management and choice of cultivars[3]. Even in tropical latitudes, the plant has succeeded at high elevations, producing fruit at elevations over 3,000 metres in Ecuador for example[4]. An easily grown plant, it succeeds in most fertile soils, preferring a moisture retentive well-drained loamy soil[5, 3]. Grows well in heavy clay soils, though if these are poorly drained there could be problems with diseases such as canker[3]. Prefers a sunny position but succeeds in partial shade though it fruits less well in such a situation[5, 3]. Tolerates a pH range from 6 to 7, preferring a range of 6.5 to 6.8[3]. Where space is at a premium, or at the limits of their climatic range, apples can be grown against a wall. Most cultivars will grow well against a sunny south or west facing wall, an east facing wall will suit many of the tougher cultivars and even a north facing wall can be used for early culinary cultivars[6]. There are very many named varieties[7, 8, 3] and with careful choice of these varieties it is possible to provide freshly harvested fruit from July to December and stored fruit for the rest of the year. The cultivated apple has been shown to be derived from Malus sieversii, with minor input from other species including Malus dasyphylla, Malus praecox, Malus pumila and Malus sylvestris. (see Riccardo Velasco et al, The genome of the domesticated apple (Malus × domestica Borkh.Nature Genetics 42, 833-839 (2010)). When chives (Allium schoenoprasum) or other alliums are grown under apple trees it can prevent or cure scab[9]. A spray of the infused leaves of Equisetum spp can also be used against scab[9, 10]. If climbing nasturtiums (Tropaeolum majus) are grown into the tree they can repel woolly aphis[9, 10]. Apples lose their flavour if they are stored with potatoes[9]. They will also impart a bitter flavour to carrots or potatoes if they are stored in the same area[10]. Growing apples near potatoes makes the potatoes more susceptible to blight[10]. Wrapping maple leaves (Acer spp) around apples in store helps to preserve the apples[9, 11]. Apples store better if they are grown in a sward that contains a high percentage of clover[10]. Apple trees grow better and produce better quality fruit when foxgloves (Digitalis spp) and wallflowers (Erysimum cheiri) are growing in the orchard[10]. Dandelions (Taraxacum spp) produce ethylene gas and this can cause earlier ripening of fruit if plants are growing in an orchard[9]. The fruit is a good wildlife food source, especially for birds[3]. Hybridizes freely with other members of this genus[3]. Plants in this genus are notably susceptible to honey fungus[3].

Propagation

Seed - this species is a hybrid and will not breed true from seed, though some interesting new fruiting cultivars can be produced.. It is best sown as soon as it is ripe in the autumn in a cold frame. It usually germinates in late winter. Stored seed requires stratification for 3 months at 1°c and should be sown in a cold frame as soon as it is received[3]. It might not germinate for 12 months or more. Prick out the seedlings into individual pots as soon as they are large enough to handle. If given a rich compost they usually grow away quickly and can be large enough to plant out in late summer, though consider giving them some protection from the cold in their first winter. Otherwise, keep them in pots in a cold frame and plant them out in late spring of the following year. Cuttings of mature wood, late autumn in a frame[12].
