post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. sungun, nw iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. in this study, simple directional vario...

The effect of ethylene on the growth rate of pollen tubes in styles of Petunia hybrida was examined. Apart from its strong inhibition of pollination-induced ethylene synthesis, aminoethoxyvinylglycine, placed on the stigma, did not impede tube growth. The inhibitors of the action of ethylene, silver thiosulfate and 2,5-norbornadiene, were similarly ineffective. Application of the ethylene precu...

the work described here is unique since the low seeded (0-6 seeds per fruit) kinnow (citrus reticulata) germplasm was grown in dense plantation (p p: 1foot and l l: 2 feet) in the niab (nuclear institute for agriculture and biology, faisalabad, pakistan) field. growth and development patterns of the fruits were studied. the low seeded germ-plasm contains 3,500 plants developed through natural a...

background : wilson disease (wd) is an autosomal recessive progressive degeneration of hepatolenticular tissue that causes the increase of copper deposition in the liver and other organs, with resultant hepatic, neurologic and psychological manifestations. wd is fatal if left untreated. the aim of the current study was to evaluate the clinical and para-clinical findings in children with wd in s...

Neck shrivel is a fruit disorder of european plum ( Prunus domestica L.). We investigate whether an asymmetrical distribution osmolytes might explain the observations turgid stylar end and flaccid stem end, in selection 17 cultivars sourced from two sites. The osmotic potential (Ψ Π ) juices expressed or samples decreased (became more negative) during development. cell turgor P slightly increas...
