Auriculas are hardy perennials that endure severe weather conditions without difficulty.
Garden Auricula pubescens Cultivation Tips Ideal for partially shaded positions on rockeries or borders, or spring flower beds, pots, tubs Water in very dry spells but plant in well drained soil. Best grown in a position that gives them shade from midday sun. Only a few have ‘Farina’ the white powder found on leaves and flowers that resembles flour or meal which is a must on Show Auriculas. Some are European primula hybrids and occasional are scented. There is now an increasing number of doubles including striped doubles at NAPS shows. The Fantasia variety is deep maroon with white frosting a real eye-catcherīorder or Garden Auriculas have old names like Dusty Miller, Recklasses and Ricklers. Doubles arise from mutations of border or garden Auriculas and were amongst the first novelties cultivated and shown. Stripes have recently been reintroduced with Monmouth Star having red petals with yellow rays out to the flowers edge.ĭouble Auricula ‘Sibsey‘ is a blue to purple flower and can be found at Specialist grower Angus Auriculas. Selfs (all one colour) and Edges including most stripes have an outside edge composed of leaf tissue such as the ‘Orlando’ a grey edged show Auricula. Show Auriculas are considered to be the star Auricula plants and must have a ring of dense Farina around the eye of the flower. Alpine Auriculas have either a golden yellow or cream centre surrounding the tube. The ‘Long Tom’ pots are silghtly taller than the traditional pot and are useful as Auricula tend to grow a ‘carrot root’ used to anchor the plant in the wild. These Alpine Auriculas look excellent when grown in 3 inch pots. First I will water well and add some dilute feed. I have been please with a powder blue flower that I hope to propagate by division in July. This study provides a new perspective for controlling safety during the growth of edible fungi and maintaining the quality of processed products.This spring has been a good one for my Auriculas. Experiments to distinguish the effects of 10 exogenous substances on GGT and C-S lyase indicated that cysteine (Cys) and glutamic acid (Glu) inhibited the production of endogenous formaldehyde by 17.13% and 14.89%, respectively. RAA is a critical period for interventions to reduce endogenous formaldehyde contents.
The activities of γ-glutamyl transpeptidase (GGT) and l-cysteine sulphoxide lyase (C-S lyase) were highest in RAA they promoted endogenous formaldehyde production. auricula (RAA) had the highest endogenous formaldehyde content. The results showed that formaldehyde was positively correlated with soluble protein and melanin levels it was negatively correlated with the total sugar and flavonoid contents. auricula were used to assess the nutritional composition (polyphenol monomers, 5′-nucleotides, organic acids and water-soluble vitamins) and related enzyme activities the correlation between quality and endogenous formaldehyde content was also analysed. In this study, different growth stages of A. To maintain quality and reduce endogenous formaldehyde content in the edible fungus, Auricularia auricula, the critical period of formaldehyde generation was identified and controlled.
