Variability in seedling emergence for European and North American populations ofAbutilon theophrasti
Some local cultivars and wilds of Iwateyamanashi (Pyrus ussuriensis var. aromatica) that grows wild in Northern Tohoku, Japan have good aromatic fruit. Iwateyamanashi may be valuable germplasms as a donor of odor compounds in breeding of Japanese pear (Pyrus pyrifolia), because almost all Japanese pear cultivars have faint odor. Fruits odors from a local cultivar 'Sanenashi', a wild accession (...
Chenopodium album seedling emergence studies were conducted at nine European and two North American locations comparing local populations with a common population from Denmark (DEN-COM). Mortality risk. Weedy plant life history conforms to the time of mortality risk from either the environment (e.g. frozen soil in the winter) or cropping systems practices (e.g. herbicide use). C. album life his...
In order to elucidate the role of maleic hydrazide (MH, 1,2-dihydro-3,6-pyridazinedione; coline salt) in increasing ̄ower bud formation on the Japanese pear, the effect of MH on cytokinin contents in the lateral buds of Japanese pear shoots were investigated. Foliar application of MH at 2600 mg lÿ1 increased zeatin, zeatinriboside, and isopentenyladenine levels in lateral buds though isopenteny...
It is previously known that under inflation alone a spherical rubber membrane balloon may bifurcate into a pear shape when the tension in the membrane reaches a maximum, but the existence of such a maximum depends on the material model used: the maximum exists for the Ogden model, but does not exist for the neoHookean, Mooney-Rivlin or Gent model. This paper discusses how such a situation is ch...
