increasing product marketability and introduction of new cultivars for fresh consumption of apple is the world's most important breeding objectives. in this study, the qualitative and quantitative characteristics of the genotypes from cross between red spur and golab-e-kohanz apple cultivars were evaluated. a total of 19 traits including fruit attributes (firmness, fruit weight,...) and th...

GRAS genes encode plant-specific transcription factors that play important roles in plant growth and development. However, little is known about the GRAS gene family in apple. In this study, 127 GRAS genes were identified in the apple (Malus domestica Borkh.) genome and named MdGRAS1 to MdGRAS127 according to their chromosomal locations. The chemical characteristics, gene structures and evoluti...

effect of foliar spraying by humic acid on mineral leaf composition, yield and fruit quality of apple (malus domestica l. cv. ‘granny smith’) was studied. an experiment based on randomized complete design was conducted in khorramdare city of zanjan province. spraying of humic acid was conducted in four levels 0, 5, 10 and 15 mg/l on eight year-old ‘granny smith’ apples grafted on mm106 rootstoc...

To study the induced resistance in apple against Valsa mali var. mali (Vmm), a Vmm-apple callus interaction system was developed to evaluate the induced resistance of an attenuated Vmm strain LXS081501 against further infection by a virulent Vmm strain LXS080601. The infection index was up to 97.32 for apple calli inoculated with LXS080601 alone at 15 days after inoculation whereas it was only ...

Apple concentrate juice industry generates a flavored coproduct (apple aroma) recovered in the evaporation process, which is poorly valuated due to lack of chemical characterization and standardization. In this study, apple aroma was characterized, allowing for identification 37 compounds, majority esters (20), alcohols (7), aldehydes (4). The storage temperature did not affect its volatile com...

The aim of the present study was to investigate the importance of the preculture conditions on the survival of apple (Malus domestica Borkh., cv. Romus4 and rootstock M106) shoot tips cryopreserved using a combined droplet vitrification procedure. Preculture was critical for the survival of apple shoot tips after cryopreservation. Among the different tested sugars and sugar alcohols (glucose, s...

High temperature is one of the most important environmental factors that affect the successful cultivation of apple (Malus × domestica Borkh). The expression of genes related with anthocyanin synthesis and sugar accumulation by high temperature treatment was investigated in the fruits of “Fuji” apple at different developmental stages in different temperature conditions through realtime PCR. In ...

A polygalacturonase (PGase) was purified from Trichoderma harzianum , grown on citrus peel, by anion exchange and size exclusion chromatographies. The enzyme had molecular mass of 29 kDa. The extent of hydrolysis by PGase was decreased with increasing of pectin esterification degree. m m ax K and V , using polygalacturonic acid as substrate, were 1.42 mg and 0.66 ìmol reducing sugar, respective...

This study represents the first paper of the effects of growth regulators on the physiochemical and phytochemical properties of the wax apple fruit, a widely cultivated fruit tree in southeast Asia. Net photosynthesis, sucrose phosphate synthase (SPS) activity, peel color, fruit firmness, juice content, pH value, total soluble solids (TSSs), and the sugar acid ratio were all significantly incre...

Apple farming cultivation is expanding in Balochistan. But there is no scientific study present on this subject which apple genus is beneficial according to nutritional point of view. This is the main object of this study to evaluate the nutritive composition of different Genus of apples. Keeping this objective in mind two different genus of apples were selected i.e. Malus Sylvestris and Malusd...
