Phenology can directly reflect the characteristics of rubber seedling, people determine agricultural time arrangements seedling germination, cut back, tending management and nursery operation. In this study, phenological period top leaf hevea tree seedlings was divided into four treatments, back carried out in sprout period, bronze stage, light green stage stable respectively. The effects sawin...

safflower oil seed has high adaptability to different kinds of abiotic stresses such as drought and salinity. the aim of this study was to evaluate the effects of drought stress at different phenological stages on relative water content (rwc), leaf canopy temperature, seed yield and its components in spring types of safflower. the study was carried out in east azarbaijan research center for agr...

A refined hybrid polarimetric decomposition and inversion method for soil moisture estimation under vegetation is investigated for its potential to retrieve soil moisture from vegetated soils in TERENO observatories. The refined algorithm is applied on Lband fully polarimetric data acquired by DLR’s novel F-SAR sensor. Two flight and field measurement campaigns were conducted in 2011 and 2012 f...

We tested the hypothesis that intensity and duration of Macrosiphum euphorbiae infestations in tomato depend on both age (phenological stage) host plant initial number aphids present colony. compared effects three levels infestation two phenological stages (pre-flowering flowering stages) curves. The position peak over time was significantly affected by phase. Populations M. reached highest abu...

Reproductive phenology is likely to vary spatially with environmental conditions that alter microclimate, in particular temperature. We hypothesized that within the same plant community type, environmental changes produced by recent burning would alter plant phenological patterns and temporal structure of the plant community. Specifically, we predicted accelerated flowering and fruiting dates i...

Low larkspurs (Delphinium nuttalliunum Pritz., Delphinium andersonii Gray) and plains larkspur (Delphinium geyeri Greene) often poison cattle grazing on western North American rangelands. The dominant toxic alkaloid in larkspur is methyllycaconitine (MLA); other very toxic alkaloids in low and plains larkspurs are nudicauline and geyerline. Toxic alkaloid concentrations in larkspur near or abov...

Abstract. Agricultural production is largely determined by weather conditions during the crop growing season. An important aspect of yield estimation concerns growth development. The occurrence meteorological events such as frosts, droughts or heat stress life cycle certain phenological stages helps explain fluctuations common arable crops. We developed a methodology and visualisation tool for ...

Plant architecture is commonly defined by the adjacency of organs within the structure and their properties. Few studies consider the effect of endogenous temporal factors, namely phenological factors, on the establishment of plant architecture. This study hypothesized that, in addition to the effect of environmental factors, the observed plant architecture results from both endogenous structur...
