A pot experiment was carried out during two successive seasons of
200212003 and 200312004 on cherrygotd plant (Chrysanthemum carinatum) at the
Experimental Station of Ornamental Plants. Fac. of Agric .. Mansoura Univ., This work
aimed to study the tolerance of cherrygold plants to salinity stress using 4 levels of
salinity (0.0, 2.5, 5 and 10% of sea water) as well as treating with some micro-
elements (Fe. Mn, and Zn) 0.15% either solely and/or in combination (2:1:1) as a foliar
application added three times to improve the growth, yield and its components, as well
as chemical constituents. Relevant data revealed that there were steadily significant
reductions in vegetative growth characteristics, inflorescences, yield. and content of N
and P while K content was increased due to higher salinity levels. As (or micro-
elements, concerned results indicated significant increase of plant growth characters
due to foliar application with either single and/or in combinations of micro-elements in
both seasons.
In addition. relevant results suggested successfully the possibility of foliar
application with microelements to improve salinity tolerance of the pot cherrygold
plants whereas, salinity caused an alteration of nutrient uptake under salinity
conditions. Therefore, the combined treatment of lower level of saline water and
spraying with micro-elements may be recommended tor improving growth, yield and
chemical constituents of cherrygold plants.
