Despite problems of low fruit set, small fruit size and alternate bearing, the Hass cultivar dominates commercial avocado production worldwide. To increase yield and fruit size, gibberellic acid (GA3) (25 mg L−1) was applied at different stages of ‘Hass’ avocado tree phenology: (i) mid–late April (flower abscission), end of June–beginning of July (fruit abscission and beginning of the exponenti...

– Introduction. Fruit ripening is the process resulting in changes in color, taste and texture, which make the fruit acceptable for consumption. Since a wide spectrum of physiological, biochemical and organoleptic changes are involved in the development of a soft, edible, ripe fruit, we studied theses changes in an underutilized fruit, khirni [Manilkara hexandra (Roxb.) Dubard]. Materials and m...

deficit irrigation is an essential optimization method for water consumption in irrigated lands. in order to investigate the effects of deficit irrigation on growth, yield and quality traits of two tomato (lycopersicon esculentum mill.) cultivars a factorial layout based on randomized complete block design with three replications was conducted in agricultural research station of miandoab during...

Supplementary lighting is frequently applied in the winter season for crop production in greenhouses. The effect of supplementary lighting on plant growth depends on the balance between assimilate production in source leaves and the overall capacity of the plants to use assimilates. This study aims at quantifying the source-sink balance and carbohydrate content of three tomato cultivars differi...

The development of fleshy fruits involves complex physiological and biochemical changes. After fertilization, fruit growth usually begins with cell division, continues with both cell division and expansion, allowing fruit set to occur, and ends with cell expansion only. In spite of the economical importance of grapevine, the molecular mechanisms controlling berry growth are not fully understood...

The effects of elevated O2 alone or in combination with elevated CO2 atmospheres for postharvest decay control on strawberry fruit (Fragaria×ananassa Duch.) were assessed. In vitro and in vivo growth of Botrytis cinerea Pers.:Fr. and the effects on fruit quality were determined under eight atmospheres: air, 40, 60, 80, 90 and 100 kPa O2, 40 kPa O2+15 kPa CO2 and air+15 kPa CO2. The commercially...

The efforts were made to study the impact of vermicomposted and composted farmyard manure (FYM) along with some combination of NPK fertilizers, on field crop of garlic (Allium stivum L.). A total of six experimental plots were prepared: T1 (recommended doze of NPK), T2 (vermicompost @ 15t/ha), T3 (20 t/ha vermicompost), T4 (15t/ha vermicompost + 50 % NPK), T5 (15t/ha farmyard manure), and T6 (f...

BACKGROUND AND AIMS The xylem in fruit of a number of species becomes dysfunctional as the fruit develops, resulting in a reduction of xylem inflow to the fruit. Such a reduction may have consequential effects on the mineral balance of the fruit. The aim of this study was to elucidate the dynamics and nature of xylem failure in developing apples (Malus domestica) showing differing susceptibilit...

Preclimacteric 'Rocha' pears stored under chilling conditions, had a larger increase of ACO (1-aminocyclopropane-1-carboxylate oxidase) activity and softened faster than those treated with ethylene. Non-treated fruit did not ripen or soften, acquired a rubbery texture, and showed barely detectable levels of ACO activity. The transcript accumulation of seven genes encoding cell wall modifying en...

fruit yoghurt is frequently made with fermented milk products; however, the use of fruit and its products may cause changes in the viscoelastic properties, syneresis and sensory properties of fruit yoghurt. one approach to improve these properties in fruit yoghurt is the use of thickening agents. this study investigated the effect of carboxymethyl cellulose and guar thickening agents on the pro...
