In Japanese pear, the application of GA3+4 during the period of rapid fruit growth resulted in a marked increase in pedicel diameter and bigger fruit at harvest. To elucidate the relationship between pedicel capacity and fruit growth and to determine the main factor responsible for larger fruit size at harvest, fruit growth and pedicel vascularization after GA application were examined and the ...

We consider completely invariant subsets A of weakly expanding piecewise monotonic transformations T on [0, 1]. It is shown that the upper box dimension of A is bounded by the minimum tA of all parameters t for which a t-conformal measure with support A exists. In particular, this implies equality of box dimension and Hausdorff dimension of A.

Mechanical fruit grading and automatic fruit grading have been detailed in this paper. The studies and applications of mechanical fruit grading, and computer visual and automatic fruit grading were also particularized. Computer vision technology for detecting fruit size, color, bruise and surface defects and evaluation of fruit overall quality were discussed. The primary problems and developmen...

A multi-component systems approach is proposed to reduce the risk of oriental fruit fly infestation in ‘Sharwil’ avocados exported from Hawaii into the United States to an acceptable level. This systems approach is based on poor host status, limited distribution and low prevalence. Recent surveys suggest oriental fruit fly populations are naturally low in Hawaii’s small avocado orchards. Mainta...

the effects of rootstocks such as 'sour orange' (citrus aurantium l. var. ‘yerli’), 'carrizo' and 'troyer citranges' (citrus sinensis osb. x poncirus trifoliata raf), 'smooth flat seville sour orange' (citrus spp. hybrid of uncertain origin), 'brazilian sour orange' (citrus aurantiam l. var. ‘brasilian’), 'volkameriana' (citrus volkameriana tan. and pasq.) and 'calamondin' (possibly citrus reti...

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...

fruit productivity and quality of eight years peach and nectarine cultivars (rich lady, ryan sun, ruby diamond and venus) grafted onto cadaman-avimag, viking, atlas, gxn 15, gf 677, mrs 2/5 and nemaguard (control) rootstocks were evaluated. a split plot experimental design was used, with each rootstock/scion combination as an experimental unit. total yield, fruit size distribution, number of fr...
