Furthermore, these results suggest that sap flow and transport of other phloem-mobile nutrients and signalling molecules could be regulated independently of sugar loading into the phloem, potentially influencing carbon鈥搉utrient homoeostasis and the distribution of signalling molecules in plants ...
Transpiration and Plant Water Balance Theodore T. Kozlowski, Stephen G. Pallardy, in Physiology of Woody Plants (Second Edition), 1997 Velocity of Sap Flow Several investigators have attempted to estimate the rate of sap flow through tree stems. Two general approaches have been employed: (1) ...
On the other hand, DASTUR and DESAI (10) founid that in the respiration of rice the carbon dioxide evolved exceeded the utilization of sugar and they believe that acids formed durino the synthesis of protein form the source of the... FC Steward,PR Stout,C Preston - 《Plant Physiology》 ...
the recruitment and the selection of host-adapted microorganisms is of importance for crop health and nutrition7,8. It has even been suggested that plants and their associated microbiome are collectively forming holobionts and therefore should no longer...
in daily sap flow whereas trees with only partial sapwood severed (PAR; estimated 2–5 % sapwood remaining) and no sapwood severed (CON; phloem girdled control) experienced average reductions of 74.3 % and 4.6%, respectively. Sapwood severing in TOT trees resulted in declining midday shoot ...
The plant wilt pathogenRalstoniasolanacearumthrives in the water-transporting xylem vessels of its host plants. Xylem is a relatively nutrient-poor, high-flow environment butR. solanacearumsucceeds there by tuning its own metabolism and alteringxylem sapbiochemistry. Flow influences many traits that the...
The higher expression of asparaginase also suggests the flow of nitrogen source into the sap. Divol et al. (2005) [11] reported that several genes which were involved in nitrate and sugar remobilization in celery, including glutamine synthase, were induced by aphid infestation. Our study also ...
Maple sap is a complex nutrient matrix collected during spring to produce maple syrup. The characteristics of sap change over the production period and its composition directly impacts syrup quality. This variability could in part be attributed to change
Mycoheterotrophic plants (MHPs) are leafless, achlorophyllous, and completely dependent on mycorrhizal fungi for their carbon supply. Mycorrhizal symbiosis
The growth of saplings20can be encouraged by cutting or genetic selection so that they grow in a multi-stemmed manner, such as shown in FIG. 3. A different stem21can be cut each spring to generate good sap flow and to encourage the development and growth of new stems while maintaining ...
