A field experiment was carried out during two
successive seasons of 2018/2019 and 2019/2020 in Floriculture farm
of Horticulture Department, Faculty of Agriculture, Benha
University to study the effects of spraying some growth substances of
kinetin, Salicylic acid, Calcium Thiosulfate and potassium Silicate as
well as, chemical fertilization (N.P.K) on vegetative growth and
chemical composition of Matthiola incana plants to increase and
improve the quality of this plant to bed gardens ornamentation.
Obtained results showed that the tallest plants and the thickest plant
stem were recorded by 100 ppm kinetin combined with NPK
fertilization at the high level treatment in both seasons. The heaviest
fresh and dry weights of leaves/ plant were recorded by 100 ppm
kinetin-sprayed plants enriched with NPK fertilization at the high in
both seasons. The highest number of branches and leaves / plant were
recorded by 100 ppm kinetin-sprayed plants combined with NPK
fertilization at the high level in both seasons. The highest leaf N and
total carbohydrates content were recorded by 100 ppm kinetinsprayed plants provided with NPK fertilization at the high level,
whereas the richest leaf P content was registered by 200 ppm
salicylic-sprayed plants combined with NPK fertilization at the high
level. While, the greatest leaf K content was scored by 6 cm
potassium silicate-sprayed plants supplemented with NPK
fertilization at the high level in both seasons. Conclusively, spraying
Matthiola incann plants with kinetin at 100 ppm and fertilized them
with chemical fertilizer at 100N: 200P; 200K kg/fed. produced the
best vegetative growth and quality of this plant. |
