BACKGROUND Carbon assimilation and leaf-to-fruit sugar transport are, along with plant water status, the driving mechanisms for fruit growth. An integrated comprehension of the plant water and carbon relationships is therefore essential to better understand water and dry matter accumulation. Variations in stem diameter result from an integrated response to plant water and carbon status and are ...

Architectural analyses of temperate tree species using a chronological approach suggest that the expression of epicormic branches is closely related to low growth rates in the axes that make up the branching system. Therefore, sole consideration of epicormic criteria may be sufficient to identify trees with low secondary growth levels or with both low primary and secondary growth levels. In a t...

Stem/branch maintenance respiration for a stand of Japanese red pine (Pinus densiflora) during the dormant season was examined using an open flow system. The stem/branch respiration rates per unit of volume were closely related to the thickness of the stems and branches, e.g. it decreased with increasing diameter (p<0.0001). When the respiration rates on the various positions were regressed aga...

abstract application of salicylic acid (sa) as a phytohormone has been increased due to its role in plant tolerance to environmental stresses such as drought. the main goal of this experiment was to evaluate the effects of sa on morphological and physiological characteristics of cucumber seedlings under drought stress. a factorial experiment based on completely randomized block design was condu...
