an increasing world population and the competitive nature of the stone fruit market, particularly nectarines [(prunus persica var. nectarine)], demand the selection of fruit with high quality attributes, flavor, and a wide range of maturity. information on this subject is limited at the present time. in search of superior nectarines, a trial was conducted to study growing degree days (gdd), ful...

this experiment was carried out in 2003-2004 to determine fruit set patterns in four pistachio cultivars (akbari, ahmad aghaie, kalle ghouchi and ohadi) to find out the correlation between final fruit set and embryonic sac development, and as well between primary fertility and final fruit set. in a field experiment, inflorescence schematic shape and position of flowers (on inflorescence on the ...

iran, with a long history of apricot cultivation is one of the most important apricot producers in the world. centuries of sexual reproduction via seed, have developed many divergent variations of apricots in iran. however, unfortunately there is no comprehensive report available concerning its diversity and genetic make-up. in this study, 39 iranian apricot cultivars as well as accessions, nat...

Scatter-hoarding rodents can act as both predators and dispersers for many large-seeded plants because they cache seeds for future use, but occasionally forget them in sites with high survival and establishment probabilities. The most important fruit or seed trait influencing rodent foraging behavior is seed size; rodents prefer large seeds because they have higher nutritional content, but this...

Seed size is a key functional trait that affects plant fitness at the seedling stage and may vary greatly with species fruit size, growth form and fecundity. Using structural equation modelling (SEM) and correlated trait evolution analysis, we investigated the interaction network between seed size and fecundity, postfire regeneration strategy, fruit size, plant height and serotiny (on-plant see...

Many quantitative trait loci (QTLs) for quality traits have been located on the tomato genetic map, but introgression of favourable wild alleles into large fruited species is hampered by co-localizations of QTLs with antagonist effects. The aim of this study was to assess the growth processes controlled by the main QTLs for fruit size and composition. Four nearly isogenic lines (NILs) derived f...

HE linear order of four genes in chromosome I of the tomato has T been well established, principally from data obtained by LINDSTROM (1932) and MCARTHUR (1934). LESLEY (1931) has shown one of the genes in this linkage group to be related to resistance to the curly top virus disease, and LINDSTROM (1932) has demonstrated a decided relationship between fruit size and the genes in this pair of chr...

Grading and classification of fruits is based on observations and through experiences. The system utilizes image-processing techniques to classify and grade quality of fruits. Two dimensional fruit images are classified on shape and colour based analysis methods. However, different fruit images may have similar or identical colour and shape values. Hence, using colour or shape features analysis...

Studies on the effect of fruit size on endogenous ABA and isopentenyladenine (iP) in developing avocado (Persea americana Mill. cv. Hass) fruit revealed that ABA content was negatively correlated with fruit size whilst the iP/ABA ratio showed a linear relationship with increasing size of fruit harvested 226 d after full bloom. The effect of this change in hormone balance on the relationship bet...
