| two types of matter economy for the wintering of evergreen shrubs in regions of heavy snowfall. | plant adaptation to an environment subject to heavy snowfalls was investigated in four species of evergreen shrubs growing in a fagus crenata forest in an area of honshu on the sea of japan. these shrubs stored carbohydrates in some organs before the snowy season and were covered with snow for 4-5 months. aucuba japonica var. borealis, camellia rusticana, and ilex crenata var. paludosa maintained a reserve of carbohydrates during the snowy season. in daphniphyllum macropodum var. humile, the res ... | 2003 | 12750947 |
| hydraulic conductivity, photosynthesis and leaf water balance in six evergreen woody species from fall to winter. | to confirm that freeze-thaw embolism is a primary stress for evergreen woody species in winter, hydraulic conductivity, photosynthesis and leaf water potential were measured during fall and winter in trees growing in a cool temperate zone (nikko) and in a warm temperate zone (tokyo). we examined two evergreen conifers that naturally occur in the cool temperate zone (abies firma siebold & zucc. and abies homolepis siebold & zucc.), and four evergreen broad-leaved woody species that are restricted ... | 2005 | 15631978 |
| meloidogyne incognita and m. arenaria reproduction on dwarf hollies and lantana. | meloidogyne incognita and m. arenaria reproduction and host plant tolerance were assessed in field and greenhouse experiments on seven holly cultivars including ilex glabra 'shamrock', i. vomitoria 'schelling's dwarf', i. cornuta 'carissa', red holly hybrid (ilex little red), and i. crenata 'compacta', 'green luster', and 'helleri' as well as japanese boxwood (buxus microphylla) and two lantana cultivars (lantana camara 'miss huff' and 'new gold'). boxwood had the highest m. arenaria and m. inco ... | 2001 | 19265898 |
| japanese hollies: intolerant hosts of meloidogyne arenaria in microplots. | japanese hollies were itttolerant of meloidogyne arenaria in field microplot experiments. ilex crenata var. rotundifolia was relatively more tolerant than i. crenata var. convexa or i. crenata var. helleri. when m. arenaria was added at various itfitial population densities to soil containing plants of "helleri," "convexa," and "rotundifolia," respectively, 91, 75, and 25% were killed by the end of the third growing season. no control plants died during the same period. initial numbers of m. are ... | 1977 | 19305618 |
| susceptibility of japanese holly to criconemoides xenoplax, tylenchorhynchus claytoni, and certain other plant-parasitic nematodes. | three cultivars of ilex crenata: 'helleri', 'convexa', and 'rotundifolia' were inoculated with either criconemoides xenoplax, helicotylenchus dihystera, hoplolaimus galeatus, trichodorus cltristiei, or tylenchorhynchus claytoni at 0, 200 (low), or 2,000 (high) nematodes/ 15-cm diam pot. plants were kept in the greenhouse 10 mo prior to transplanting into 2.25 m(2) field plots. helleri was severely stunted by c. xenoplax. criconemoides xenoplax and t. claytoni caused lower plant vigor and top wei ... | 1976 | 19308191 |
| first report of xiphinema brevicolle lordello et costa, 1961 (nematoda, longidoridae) in japan. | mixed populations of xiphinema americanum-group species were detected from a root zone soil sample of japanese holly, ilex crenata, during a survey for plant-parasitic nematodes of commercial ornamental plant nurseries in chiba prefecture, japan. from the result of the morphological study, the species were identified as xiphinema brevicolle and xiphinema sp. this is the first record of xiphinema brevicolle in japan. morphometrics of xiphinema brevicolle generally agree with those of the type spe ... | 2011 | 22259299 |
