“…Performance in urban areas can be improved by injecting sucrose solution (50 g/L) into the soil around the roots. Percival, Fraser, and Barnes () found this to increase fine root dry mass (>4 mm diameter) from 0.24 to 1.17 g/m 3 5 months after treatment. This was also seen to work for Betula pendula and Quercus robur but not Prunus avium .…”

Biological Flora of the British Isles:Aesculus hippocastanum

This account presents information on all aspects of the biology of Aesculus hippocastanum L. (horse‐chestnut) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history and conservation. Aesculus hippocastanum is a large deciduous tree native to the Balkan Peninsula. Native populations are small (<10,000 trees total) and apparently in decline, but the tree has been widely planted in gardens and streets across Europe and other temperate areas from the 17th century onwards. It was voted the UK's favourite tree in a 2017 poll. As a British neophyte, it is occasionally naturalised in open wooded habitats. Horse‐chestnut is renowned for the beauty of its large (up to 30 cm long), upright panicles of white flowers, and for the large seeds (up to 42 g each) used in the formerly common children's game of “conkers.” More recently, the triterpene glycosides, extractable from various plant parts but especially the seeds, have been widely used in medicine. In much of Europe, horse‐chestnut is affected by chestnut bleeding canker (caused by Pseudomonas syringae pv. aesculi), the horse‐chestnut leaf miner Cameraria ohridella and the leaf blotch fungus Guignardia aesculi. The canker is likely to lead to death of <10% individuals, but seeds of plants infested with the leaf miner are 40%–50% smaller, which may affect long‐term establishment in non‐planted areas.

“…El diseño experimental fue completamente al azar; los tratamientos consistieron en cuatro concentraciones de glucosa: 0 (testigo), 30, 55 y 80 g L -1 ; el testigo solo contenía agua purificada. La distribución de los tratamientos fue aleatoria con nueve repeticiones por cada tratamiento (Percival et al, 2004;Martínez et al, 2009).…”

“…El suministro exógeno de carbohidratos al sistema vascular de árboles tiene un efecto positivo en su desarrollo, debido al incremento de las reservas de energía (Percival et al, 2004;Martínez et al, 2009;Martínez et al, 2013). Si bien las inyecciones al tronco surgieron para el tratamiento químico de enfermedades, hongos y plagas (Costonis, 1981;Perry et al, 1991;Dal Maso et al, 2014;Acimovic et al, 2015), recientemente se han utilizado como la opción más viable para mejorar el estado del arbolado urbano (Martínez et al, 2009;Percival y Sacre, 2014;Suryanto et al, 2018).…”

Los árboles de jacaranda son comunes en áreas urbanas del valle de México y se desarrollan frecuentemente bajo condiciones de estrés nutricional o hídrico, lo que restringe el crecimiento del arbolado. El suministro de carbohidratos a través del sistema vascular recientemente se ha recomendado como una opción para mejorar el crecimiento y vitalidad. Por lo anterior, el objetivo del trabajo fue evaluar el efecto de la glucosa sobre crecimiento y vitalidad de árboles de Jacaranda mimosifolia inyectada al tronco en cuatro concentraciones: 0 (testigo), 30, 55 y 80 g L-1 Se midieron incrementos en diámetro (cm) y altura (m), se monitoreó la condición de copa y producción de follaje y además se evaluó el contenido de carbohidratos en brotes, troncos y raíces, así como la fluorescencia de la clorofila (Fv/Fm). Se encontraron diferencias significativas (P≤0.05) en el incremento en diámetro y altura con la aplicación de 80 g L-1 de glucosa. La condición de copa mostró valores significativamente más altos en densidad y bajos en transparencia, así como una buena producción de follaje, con la concentración más alta del carbohidrato (80 g L-1). Su contenido presentó diferencias significativas (P≤0.05) en tronco, no así en brotes, raíces, ni en valores de fluorescencia de la clorofila. Las inyecciones de glucosa al tronco tienen un efecto significativo en el crecimiento de árboles de esta especie y afectan en menor medida la vitalidad del arbolado.

“…Consequently, research has evaluated the potential of numerous soil amendments at the time of planting to include mycorrhizae, biostimulants, sugars, and fertilizers. Results have been mixed with some studies demonstrating positive benefits on root vigor following addition of these amendments, while others little, if any positive effects (Hensley et al 1988;Edmeades 2003;Percival et al 2004;Percival and Barnes 2007).…”

“…Slow-release sugar compounds, such as molasses, have been proven to have significant effects on plant growth during germination, influencing the mobility of nutrients, shoot and hypocotyl development including suppressing elongation, cotyledon greening, and expansion (Rolland et al 2002). Evidence from several experimental studies shows that sugar supplementation to young and mature trees can enhance root invigoration by increasing lateral root growth and root metabolism (Percival et al 2004). Sugar as an organic amendment also has the potential to alter the soil rhizosphere populations, resulting in changes in plant nutrient uptake in favor of increased root growth (Blunden and Woods 1969).…”

High mortality rates result from transplanting bare-rooted plants into urban landscapes where unsuitable soil conditions, such as low fertility and poor structure, often exist. Coupled with little aftercare, these losses can cause high economic losses to the industry. Previous studies have shown lowered transplant stress and higher survival rates through the addition of soil amendments at the time of planting to improve soil conditions. The efficacy of three soil amendments applied singly and in combination—biochar, slow-release molasses, and an organic N:P:K fertilizer—were investigated for their potential to reduce transplant losses of Pyrus communis ‘Williams’ Bon Chrétien. Results of this investigation showed that use of these soil amendments in virtually all cases had significant positive effects on tree growth and vitality across two growing seasons. For example, all amendments reduced mortality of Pyrus communis ‘Williams’ Bon Chrétien’ by 20% compared to none in treated controls, while increases in fruit yield and crown canopy coverage per tree ranged from 19.3% to 46.7% and 14.4% to 31.1% over non-amended soils when averaged over two growing seasons. Amendments of biochar with an organic N:P:K fertilizer and an organic N:P:K fertilizer alone showed, on average, the highest improvements in vitality and growth. Results indicate use of biochar, slow-release molasses, and organic N:P:K fertilizer amendments offer potential for increasing bare-root transplant survival and establishment of Pyrus communis ‘Williams’ Bon Chrétien.
