Seasonal Changes in the Inorganic Constituents of vine shoots

ABSTRACT

The subject of study is t he shoot of t he

Vitia Vintera, Alphonse Le Vallee . And the general

envi ronment of' the plant is l iable to play a v ry

i mportant role in influencing the ch ~mi c a l changes

conditions, cultural pr ~ctic e s, soil compositions

and rootstocks, produce profound differenc.es in the
