ABSTRACT

A pot experiments was carried out at National Research Center,
Dokki, Cairo, Egypt, to investigate the effect of IAA (100, 200 and 400 mg∙dcm^-3),
NAA (10, 20 and 40 mg∙dcm^-3) and kinetin (25, 50 and 100 mg∙dcm^-3)
on Lupinus termis plant
growth, yield and seed chemical composition as well as hormones contents compared
with untreated plants. The obtained results indicated that the highest number
of branches was obtained with kinetin treatment, especially at 100 mg∙dcm^-3.
While, the maximum values of both number and dry weight of pods were obtained
as a result of foliar application with kinetin at 50 mg∙dcm^-3.
Spraying the lupine plants with bioregulators increased significantly the seed
number per pod and per plant, and seed yield/plant except those plants treated
with IAA at 100 mg∙dcm^-3. Applications of IAA, NAA and kinetin
treatments had no significant effect on crop index, harvest index and shelling
percentage. The maximum seed yield was recorded with the application of kinetin
at 50 mg∙dcm^-3 followed by kinetin at 100 mg∙dcm^-3 as well as
IAA at 100 mg∙dcm^-3. High levels of GA and IAA were observed
in seeds produced from plants treated by IAA relative to those treated by NAA
or kinetin. Spraying the lupine plants with the bioregulators IAA, NAA and kinetin
caused an increase in protein content and total carbohydrates and decrease of
oil percent in the lupine seeds

Key words: lupine, IAA, NAA, kinetin, endogenous hormones, seed yield.
