Animals and fruiting plants are involved in a complex set of interactions, with animals relying on fruiting trees as food resources, and fruiting trees relying on animals for seed dispersal. This interdependence shapes fruit signals such as colour and odour, to increase fruit detectability, and animal sensory systems, such as colour vision and olfaction to facilitate food identification and sel...

a study of two years was carried out on apples, red delicious cv. in comeh of semirom region. the objective of this research was to assess the effect of pre-harvest calcium phosphate (seniphos) spraying and summer pruning on the skin color and quality characteristics of the fruit. study was carried out using a complete randomized block design with 3 replications. trees were subjected to pre-har...

Annual yields per tree for ‘Starkspur Supreme Delicious’ apple (Malus domestica Borkh.) trees on nine size-controlling rootstock were related linearly to number of fruit per tree at harvest each year, independent of rootstock. Mean fruit weight was inversely and less closely related to number of fruit per tree when adjusted for tree size (fruit load). Annual yield-fruit count data for 9 years a...

Ten-year-old 'Tai So' lychee (Litchi chinensis Sonn.) trees growing on a sandy loam soil in subtropical South Africa (latitude 25 degrees S) were watered weekly (well-watered treatment) or droughted from late July until January (drought treatment). After 16 weeks, at which time the trees obtained most of their water from below 150 cm, average soil water content at 0 to 150 cm depth was 14.5 +/-...

A 2-yr study was conducted in a citrus orchard (Citrus sinensis L. Osbeck cultivar Valencia) todetermine the inßuenceofplantwater stresson thepopulationdynamicsofglassy-winged sharpshooter,Homalodisca vitripennis (Germar). Experimental treatments included irrigation at 100% of the crop evapotranspiration rate (ETc) and continuous deÞcit-irrigation regimens at 80 and 60% ETc. Microclimate and pl...

The oil content in olive fruits of different sizes from irrigated high (‘on’) and low (‘off’) yielding olive trees of cvs. Barnea and Manzanillo were determined at different stages of fruit maturation. The fruit size range at all stages of maturation is significantly higher on low yielding ‘off’ trees than on high yielding ‘on’ trees. The oil content in the mesocarp of olive fruits is not yield...

Extraordinary importance of Date-Palm, Phoenix dactylifera especially ‘Piarom’ variety and also undeniable effect of nitrogen and phosphorus on yield and quality of this product, caused this research to be accomplished. The research was performed during two years on 72 (4*3*3*2=72 trees) fruitful, 12 years old trees in Hormozgan province. Treatments were consisted of four levels of nitrogen (0,...

Shi, Biying. M.S., Purdue University, May 2015. Growth Parameters for 'Golden Delicious' Apple Trees (Malus × domestica Borkh.). Major Professor: Peter Hirst. High yield and high quality of tree fruit result from appropriate orchard design and management practices. This requires an accurate knowledge of vegetative growth, branching, and flowering processes of fruit trees. Tree development knowl...

A large collection of Botryosphaeriaceae isolates obtained from fruit and forest trees with fruit rot, canker and dieback disease symptoms in northern provinces of the country were examined in this study. Based on morphology and sequence data (ITS and EF1-α), two species, Diplodia mutila and Spencermartinsia viticola are illustrated and described as new records for Iran mycobiota. Furthermore, ...
