“…It is a popular fruit in Pakistan and is available to satisfy consumer needs in spring when no other fruit is available in the market, thus fetching good prices. However, until recently (Hussain et al, 2007), it has been neglected in terms of research. In Pakistan, most of the loquat orchards were established using seeds due to the unavailability of certified and true to type planting stock in local nurseries.…”

“…Consequently, there is a lack of uniformity among plants giving low quality fruits with low yield. Cultivation of superior genotypes of loquat may increase production, thereby increasing availability for the home market and for export (Hussain et al, 2007). Loquat cultivar Mardan has large, round, and attractive fruit with an orange yellow skin and sweet tasting pulp (Hussain, 2009) which can help it to capture local and export markets.…”

Abstract:In vitro cultures of loquat cultivar Mardan were established using shoot apices after treating with NaOCl (5%, 7%, 10%, 12%, 14% (v/v)) for 12 min and HgCl 2 (0.01%, 0.05%, 0.10%, 0.20%, 0.25% (w/v)) for 2 min. A maximum survival rate of 70% was recorded after surface sterilization with 10% NaOCl. Caulogenic response was assessed on Murashige and Skoog (MS) medium fortified with assorted combinations of the cytokinins, benzylaminopurine (BAP), kinetin, and N6-(2-isopentyl)adenine (2iP). Treatment of BAP 1.5 mg/L combined with 2iP 9.0 mg/L and kinetin 1.5 mg/L was found to be optimum for shoot morphogenesis in terms of the number and subsequent growth of shoots, while the highest shoot length was yielded by the combination of BAP 0.5 mg/L, kinetin 0.5 mg/L, and 2iP 3 mg/L. Higher levels of cytokinins induced callogenesis, vitrification and stunted growth to some extent. For rhizogenesis, uniform sized micro-shoots were excised and transferred to half-strength MS medium containing auxins. The best rooting expression was observed with naphthaleneacetic acid (NAA) 1 mg/L combined with indole-3-butyric acid (IBA) 2 mg/L and paclobutrazol (PBZ) 1 mg/L.

Spilocaea pyracanthae causing leaf scab on loquat in Pakistan

Abstract:Loquat is attacked by many phytopathogenic fungi.Among these Spilocaea pyracanthae is of economic importance. . In KPK, it is mainly cultivated in Mardan, Peshawar and Hari Pur districts while, in Punjab, it is mostly grown in the Pothowar region (Hussain et al. 2007). Loquat leaves have great significance from medicinal and nutritional point of view. In China, loquat leaves are being used as folk medicine for the treatment of pulmonary tuberculosis (Zhang et al. 2004). Loquat leaves are also used to cure various skin diseases, pain, inflammation, coughing, diabetes and liver disorders (Nishioka et al. 2002;Hamada et al. 2004;Sakuramata et al. 2004).There are numerous pathogens that attack loquat. Fire blight caused by Erwinia amylovora is a serious bacterial disease of loquat (Seymour 1965). Leaf spot incited by Diplocarpon mespili (= Entomosporium mespili) is another important disease of loquat (Batool et al. 2014) and several genera of subfamily Pomoideae of the Rosaceae family. The disease has proved itself capable of rendering an entire fruit crop unmarketable (Davidson 1985). Other pathogens reported to infect loquat include: Pseudomonas eriobotryae (canker), Phytophthora spp. (crown rot), Lasiodiplodia theobromae (= Diplodia natalensis -collar and root rot), and Colletotrichum gloeosporioides (anamorphic Glomerella) (anthracnose) (Crane and Caldeira 2006).Loquat scab is a very common disease in the Southern Italy, especially in Sicily, South Africa, around the Mediterranean basin, and in the eastern regions of North America on different hosts (Gardner and Raabe 1966;Raabe and Gardner 1972; Butt et al. 2015). Very little information is available in literature regarding loquat scab and the associated fungus Spilocaea pyracanthae. The fungus was first reported on loquat in 1909 (Smith 1909). The disease resembles pear and apple scabs in all aspects caused by Venturia pirina and V. inaequalis, respectively (Ohlendorf 1999). Loquat is highly susceptible to leaf and fruit scab especially during wet seasons when control measures are inadequate. Scabbed fruit is rendered unsuitable for market and results in economic loss (Tous and Ferguson 1996;Caballero and Fernández 2004). In Pakistan loquat is a neglected fruit tree and no attention has been paid to fungal pathogens associated with it. The current study is focused on the symptomatology of During extensive surveys of loquat orchards in 2013, spots were observed on leaves. The spotted leaves were brought to the laboratory for identification of disease symptoms and the associated pathogen. The color and shape of the spots were observed. For isolation of the pathogen, the spots were cut, and the surface was sterilized in ethanol and plated on autoclaved Potato Dextrose Agar (PDA) in 90 cm Petri plates. The plates were then incubated at 25 °C for the growth of the fungus. The fungus was purified from a single spore and identified on the basis of morphological characters (Schubert et al. 2003;Schubert and Braun 2005).The pathogenicity of the fungus was conf...

“…No obstante, la mayor parte de las variedades destacadas de esta especie proceden de hibridación como, por ejemplo, el cultivar 'Tanaka' (Lin 2007). En Pakistan existen colecciones de variedades locales bien adaptadas a la zona, algunas de las cuales se cultivan y se destinan a mercados locales (Hussain et al 2007a).…”
