Phloem Loading in Squash [PDF]
Squash (Cucurbita pepo L. var. melopepo torticalis, Bailey) leaves were supplied with (14)C-sucrose, then specific radioactivities of the glucose and galactose moieties of translocated stachyose were determined. In every case, the specific radioactivity of the galactose moiety was greater than that of the glucose moiety.

Model-Based Design of Long-Distance Tracer Transport Experiments in Plants
Studies of long-distance transport of tracer isotopes in plants offer a high potential for functional phenotyping, but so far measurement time is a bottleneck because continuous time series of at least 1 h are required to obtain reliable estimates of ...

The Puzzle of Phloem Pressure [PDF]
Although transport of organic nutrients and regulatory molecules in the phloem underlies all aspects of growth and development, we still cannot say with confidence that we adequately understand how it is motivated. A major problem is that it is difficult to reconcile the theory of pressure flow,

Plant responses to abiotic stresses entail adaptive processes that integrate both physiological and developmental cues. However, the adaptive traits that are involved in the responses to a high soil salinity during reproductive growth are still poorly ...

Phelipanche aegyptiaca parasitizes a wide range of plants, including important crops, and causes serious damage to their production. P. aegyptiaca develops a specialized intrusive organ called a haustorium that establishes connections to the host’s xylem

The present study focuses on the cambium and the anatomy of secondary tissues (xylem – wood and phloem) of Siberian poplar (Populus sibirica) and Siberian elm (Ulmus pumila) grown in a plantation in the semi-arid Mongolian steppe.

Phloem transport and drought [PDF]
Drought challenges plant water uptake and the vascular system. In the xylem it causes embolism that impairs water transport from the soil to the leaves and, if uncontrolled, may even lead to plant mortality via hydraulic failure. What happens in the phloem, however, is less clear because measuring phloem transport is still a significant challenge to ...

Solution-Flow in the Phloem [PDF]
Translocation profiles along the path were studied using a modified flap-feeding technique for the simultaneous application of THO and (14)C-sucrose. A re-evaluation of a mathematical model for phloem transport with reversible lateral exchange of tracer along the path indicates that lower apparent velocities for THO as compared to labeled carbohydrate ...

Determination of physical characteristics of root vegetables with puncture test [PDF]
The aim of this research was to analyze the physical characteristics of root vegetables: carrot, parsley, parsnip and celery. These root vegetables are sold fresh on the market which is why it is important to specify its shape, structure and root texture.
