Abstract Lisianthus (Eustoma grandiflorum) is an ornamental species used as a potted plant or cut flower, its popularity due to the diversity of colors, number flower buds, and shelf life. Nevertheless, during first phases development, problems such foliar chlorosis root diseases affects most cultivars, causing poor growth, thin stems, few flowers. The use growth-promoting rhizobacteria (PGPR) ...

Caesalpinia platyloba was evaluated as an alternative for the retention of atmospheric carbon and as a feasible and viable economic activity in terms of income for tropical deciduous forest (TDF) peasants in the carbon markets. A total of 110 trees of C. platyloba from plantations and a TDF in the Northwest of Mexico were sampled. Growth (increase in height, diameter, and volume curves) was adj...

High-resolution airborne laser scanner data offer the possibility to detect and measure individual trees. In this study, an algorithm which estimated position, height, and crown diameter of individual trees was validated with field measurements. Because all the trees in this study were measured on the ground with high accuracy, their positions could be linked with laser measurements, making val...

It has been possible to modify the sampler module of the AutoAnalyzer to enable laboratoriespossessingadditional recorder and colorimeter units to analyse two sets of specimens simultaneously. Basically the device consists of a circular plastic channel of rectangular cross-section which fits on top of the normal sample plate and carries a second ring of cups (Fig. 1). The external diameter is 1...

this study was carried out to investigate the effect of crown canopy of ziziphus spina-christi on seed bank characteristics (density and similarity with above ground flora) in two sites with saline-alkaline and alkaline soils. in each soil, forty plots were established, half in and half outside of z. spina-christi cover. in each plot, soil sampling was done from 0-5 and 5-10 cm depths. paired a...

The architecture of spray cut chrysanthemum is crucial for the quality and quantity flower production. However, mechanism underlying plant still needs to be clarified. In this study, we measured nine architecture-related traits 195 varieties during a two-year period. results showed that number upper primary branches, lateral buds branch length widely varied. Additionally, height had significant...

Recent studies of highly branched mutants of pea, Arabidopsis and rice have demonstrated that strigolactones (SLs) act as hormones that inhibit shoot branching. The identification of genes that work downstream of SLs is required for a better understanding of how SLs control the growth of axillary buds. We found that the increased tillering phenotype of fine culm1 (fc1) mutants of rice is not re...

Hundreds of cankers caused by Ceratocystis smalleyi are associated with hickory bark beetle-attacked bitternut hickory exhibiting rapid crown decline in the north-central and northeastern United States. Discolored sapwood colonized by the fungus commonly underlies the cankers. Field studies were conducted to test the hypothesis that C. smalleyi infections cause vascular system dysfunction in in...
