almond is one of the most important prunus species. most almond cultivars and genotypes are self-incompatible and some others are cross-incompatible. however, recently self-incompatible cultivars developed by breeding are available. therefore self-incompatible cultivars for pollination, fertilization and production require compatible pollen of other cultivars. in this regard the study of pollen...

Abstract Effect of coating with calcium nitrate in three concentrations (0.0, 0.5, and 1.0 wt%) on chemical mechanical properties, impact behaviour two apple cultivars (Golden Delicious (GD) Red (RD)) during time (0, 2, 4 months) was studied. Moisture content, pH, titratable acidity, °Brix, organoleptic modulus elasticity (E), yield stress, strain, toughness were measured. The effect loads dete...

extended abstractbackground and objectives: loquats have formed different ecological types during their cultivation and adaptation in different parts of the world. the first step in the breeding operation is the identifying of the spread center accompanied the studying of the variation between genotypes. in this research, 20 loquat genotypes were evaluated using fruit morphological markers to i...

The usefulness of nondestructive methods for measuring chlorophyll content in skin of ‘Golden Delicious’ apples and for evaluating quality parameters and fruit maturity using optical reflectance spectrometry was studied. The fruit weight, firmness, total soluble solids content and titratable acidity during vegetation period and short-term storage at 10°C of ‘Golden Delicious’ apples were measur...

to evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. in this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...

abstract- the evaluation of leaf area and leaf nutritional value is important for crop growth modeling and estimations of its performance. the purpose of this study was to use image processing techniques to develop an economical method to ease the assessment of nutrient status and leaf area (la) of plants and to compare the outcomes of this method with linear models. leaf area and leaf chloroph...

The ripening of climacteric fruits, such as apple, is represented by a series genetically programmed events orchestrated the action several hormones. In this study, we investigated existence hormonal crosstalk between ethylene and auxin during post-harvest three internationally known apple cultivars: 'Golden Delicious', 'Granny Smith' 'Fuji'. normal was impaired exogenous application 1-methylcy...

The sequence of events which occurs during the ripening of the Passe-Crassane pear fruit have been previously studied. In this work, we have investigated the ripening of another climacteric fruit (Pyrus malus L. cv Golden Delicious) and of a nonclimacteric fruit (Prunus avium L. cv Bigarreau Napoléon). We show that both climacteric fruits exhibit the same preclimacteric sequence of events. Diff...
