Rice protoplasts isolated directly from mature-embryo-derived calli

1996

Mature-embryo-derived calli of japonica rice (Oryza sativa L) Taipei 309 were used for replicated protoplast isolation experiments. Six out of nine callus lines produced protoplasts with satisfactory yield of 5.20×106–8.96×106 protoplasts/g FW (fresh weight). The remaining three callus lines initiated from seeds of cryopreserved-callus-derived plants had rooty calli, resulting in low yield of protoplasts and a large number of isolated banana-shape intact cells. Viability of protoplasts ranged 87.46%–94.15%. The average size of protoplasts was 207.49–379.04 μm2 in different callus lines. Comparitive experiments were also carried out using both calli and suspension culture cells for protoplas…

THE ROLE OF THE LOQUAT IN MAINTAINING ENTOMOLOGICAL DIVERSITY IN THE CONCA D'ORO ORCHARDS OF SICILY

2015

The loquat [Eriobotryo japonica (Thumb.) Lindl.] is an allochthonous species long cultivated in Sicily. In some parts of Sicily such as the Siracusa province, the loquat is cultivated in mono-specific orchards. In other sites, like Conca d'Oro and other places near the town of Palermo, loquat is intercropped with other tree species such as citrus, apricot, peach, mulberry, walnut, Mediterranean hackberry. The loquat plays an important role in order to increase biodiversity within these orchards. The old or dead loquat trees host a variety of xylophagous insects and more in particular Coleoptera: Cerambycidae beetles Dynastidae, and Cetoniidae. Longhorn beetles, rhinoceros beetles and flower…

Morphology, ultrastructure and molecular characterisation of Spiroxys japonica Morishita, 1926 (Spirurida: Gnathostomatidae) from Pelophylax nigromac…

2014

Gnathostomatid nematodes identified morphologically as Spiroxys japonica Morishita, 1926 were collected from the dark-spotted frog Pelophylax nigromaculatus (Hallowell) (Amphibia: Ranidae) in China. Light and scanning electron microscopy were used to study the morphology of this species in detail. Previously unreported morphological features are revealed and others corrected. In addition, adult nematodes of S. japonica collected from P. nigromaculatus and Spiroxys hanzaki Hasegawa, Miyata & Doi, 1998 collected from Andrias japonicus (Temminck) (Caudata: Cryptobranchidae) in China and Japan, respectively, and the third-stage larva of S. japonica collected from Lithobates catesbeianus (Shaw) …

FIRST STAGES OF MICROSPORE REPROGRAMMING TO EMBRYOGENESIS THROUGH ISOLATED MICROSPORE CULTURE IN LOQUAT

2011

The current experiments were undertaken to develop a method for regenerating doubled haploid (DH) plants of Eriobotrya japonica (Thunb.), Rosaceae, subfamily Maloideae through isolated microspore culture of nine loquat cultivars. Protocols were developed for isolation and culture of loquat microspores. Isolated microspores in vitro cultured started dividing and developing multicellular, globular and irregular structures. After 4 weeks of culture, the responding microspores produced yellowish/white callus. The embryogenic response of microspores was highly dependent on the cultivar and on the medium composition.

CHEMICAL AND SENSORY CHARACTERISTICS OF FIVE LOQUAT CULTIVARS

2015

Fruit quality can be evaluated by combining chemical-physical and sensory analyses. In this trial, both instrumental and sensory analyses were carried out on fruit of 5 loquat cultivars (‘Nespolone di Trabia’, ‘Sanfilippara’, ‘Virticchiara’, ‘MarcenA²â€™ and ‘Golden Nugget’), with the aim of assessing their commercial quality. Fruit weight, transversal and longitudinal diameter, total soluble solid content (TSS), and titratable acidity (TA) were measured. In addition, a sensory profile of each cultivar was defined by a trained panel, which generated 16 attributes. The highest fruit weight was found in ‘Golden Nugget’ and ‘Sanfilippara’; the latter exhibited also th…

Growth, Yield and Fruit Quality of 'Peluche' Loquat under Windbreak Nets.

2011

The advantages of protecting 6-year-old ‘Peluche’ loquat trees (Eriobotrya japonica Lindl.) with nets were investigated in Sicily. Vegetative and reproductive growth were measured on 20 trees under net protection and 20 in open field conditions. A neutral, 50% windbreak net (yielding 70% of light penetration) was positioned around the field and above trees to cut down wind action and other occasional extreme atmospheric phenomena. Side openings were left on the nets to provide the entrance for pollinators. Compared to trees in the open field, trees under nets showed increased vigor (trunk cross-sectional area) and fruit growth (relative growth rate), and higher yields due also to larger fru…

Influence of Cactus Pear Mucilage-Based Edible Coating on Marketability and Edibility Parameters of Minimally Processed Loquat Fruits

2022

Loquat fruit, popular all over the world for its mild, subacid, and sweet taste, has been classified as a non-climacteric fruit with a very short postharvest life. The fruit decays quickly after harvest, and losses in titratable acidity, taste, and juiciness, and internal browning occurs rapidly during shelf life. The aim of our study was to assess the effects of cactus pear mucilage-based coating on quality, nutraceutical value, microbiological growth, and sensorial parameters of minimally processed white-flesh Martorana and orange-red-flesh Gigante Rossa loquat fruits during cold storage. The effect of mucilage edible coating on the postharvest life, qualitative attributes, and nutraceuti…

GROWTH AND BIOMASS PARTITIONING OF YOUNG LOQUAT PLANTS UNDER WATER DEFICIT

2015

Water scarcity in the Mediterranean areas is very common and understanding responses to drought is important for loquat management and production. The objective of this study was to evaluate the effect of water deficit on growth and biomass partitioning of loquat. Ninety 1-year-old plants of 'Marchetto' loquat (Eriobotrya japonica Lindl.) grafted on quince were grown in the greenhouse in 12-liter pots and three water regimes were imposed starting on 11 May and until 27 July, 2013. One-third of the plants was irrigated to reintegrate 100% of the water consumed (CTR); a second group of plants was irrigated with 66% of the water consumed by CTR plants (MD); a third group was irrigated with 33%…
