The Study of Stem Recutting and Aluminum-sulphate Application on the Some Morphophysiologic Traits in Rosa (Rosa hybrida cv.illona)

Abstract

This reasear ch was conducted in agricultural f aculty of Tehran University in 2005 for evalu ation the effect of
application aluminum-sulphate levels in preserva tion solution with stem recutting on longevity of rosa hybrida cv.Illona
cut flower.Cut stems of rosa th at produced in greenhouse from biennial mother stocks was placed under treatment of
aluminum-sulphate solution with concentrations (100- 150- 200 ppm) and stem recutting in 2 levels (by cutting / without
cutting).Then in th is treated flowers, measured this tr ait include (longevity / a, b chlorophyll / water absorption content /
relative water content / tot al protein / ac tivity of peroxidase and catalase enzymes in petals .The results showed that the
different levels of aluminum-s ulphate had significant effect on senescence percent, chlorophyll content, relative water
content and activity of an ti- oxidant en zymes.Also, stem recutting levels had si gnificant effect on senescence percent,
chlorophyll content, water absorption, relative water content, total protein, activity of anti- oxidant enzymes.
Obtained results from interaction effect of between application of aluminum-sulphate and stem recutting showed that
application of alumi num-sulphate with 150 p pm together with stem recutting caused significan t incr easing in b
chlorophyll, tot al chloroph yll, water re lative con tent and activity of peroxidase and cat alase en zymes, from this wa y
caused decreasing in flower senescence percent.
