Abstract
The present investigation was conducted in the experimental area in Faculty
of Agriculture, Fayoum. Cairo UniverSity in two successive seasons of 2003/2004 and
2004/2005 The objective of this study IS to investigate the effect of paclobutrazol
(PP333l spraying at the rates of 10, 20 and 30 mg L' on growth, flowering and some
chemical constituents of sweet pea (Lathyms odoratus Li) plants, Appreciable effects
of various treatments were observed on all the studied parameters during the two
growmg seasons Spraying plants with Pn; at all rates decreased plant height, leaf
area leaf . leaf area plant' . fresh and dry weight of leaves and branches plant“, floral
stalk length, fresh and dry weight inflorescence; and flower" On the other hand. No
of branches, leaves and inflorescences plant" were increased in response to the
treatment of PPmThe flowering date as affected by Png spraying was delayed With
respect to chemical constituents: leaf pigments (chlorophyll a. b and total as well as
carotenOids). total soluble carbohydrates in leaves and flowers as well as anthocyanln
concentration in flowers were increased. However, total free amino acids and total
indoles in leaves were decreased by PP333 application Additionally. the pronounced
effect in the vegetative growth and flowering characters as well chemical constituents
were obtained when the plants were sprayed With 30 mg L‘. Final/y, in the light of
these results. it could be concluded that to produce showy flowering pot plants from
sweet pea. the plants must be sprayed with paclobutrazol at the rate of 30 mg L'l
