SUMMARY
The m~st important genu~ of t~e F~ily Lillacea~ for
the garden is probab1S L~llum.
”
These true Lilies have leng bee~ known as nGarden
Aristocarta~ or Noble plants- They add dignified glory t~
so many g~r’enB and when the, grown in pots or used as cut
flowers, the same dignified beauty prevails.
The present work wa~ undertaken at the farm of the
Faculty of Agriculture Sci~nces at Moshtohour, Zagazlg
University in three auccesa1ve season 1977/1978, 1978/1979,
8nd 1979/1980.
The present work. waB com ueted to investigate the
effect of media~ nutrition and growth regulators on propgetion
and growth of Li11um lengiflorum tb~b.
’rne first experiment was a prellm.in2,rystudy to
investigate the effects of two different media And nutrition
on the growth of the new formed bl~lb1ets of L111um
long1florum Than.a. The first medium (A) consisteo of:
1Selld:: 1,eat mass vlv, where9.s the second one wa.s 1 Sand ’:
1 peat moss: I 1 loam v/v. The bulblets alsu wera subjected
to three different levels of nut~ition as 81 and 53’ On
account of tne previouslY obtained results the first medium
w~s exolud6d and the levols of nutrition were modified to
bo 3
, The new formed bulblets of 1978
wore graded and subj·octe<lto modified nutrient solution
’ Toe same practices were repeated in 1979/
The second exprei.~nt was propag~tion frmu cuttings b,
usi~g lAA ~t 0.00. 100, i50, Z0 p.p,m. and lBA at OO.t, 100,
ZOO I 250 P.1’ .m. Rootone 00.0 and 2000 P.P .m. for both cutt.inS
and scaleS propagation whicn were pre-treated at differ<.mt
tempera tuxes tllen treatod witn the s””,e concentrations of
lAA. IBA and Rootone besides wounding treatments.
The third experiment concerned the effects of nutrition
0[1 the growth and flowering of the me.ture bulbs of
~ilium ~ong1flour~.Thunb.
The important results can Ou summcri~cd as follows:
l. The high.est nubmer of BUrv’ived and ilealthy plo.nts wM
noticed in medium (B) wh.icn conaists of 1 Sand I l 108m :
1 pc~t mosS when supp~ied with tno nign lGvel of nutrition.
Th~ intcract1onof M x N waS signifioant.
2. Bulbleta grown in mcdiwn (B) ai~ificactlY gB~e more
numbur and he,wier leaves as oompared wUIl medium (A). AlsO
using medium (B) significantl,y incre”sed tb8 w~ignts of
bulbleta.
3. Tbe nignest percentages of drY matter were those in
lc,avcS, flower st”lk and f~owers of the plants wnich received
the highest ~evel nutrition (85), The medium lavel of nutrit

In all different org~ns nutrition did not affect

6. The percentage of aurviv”l cuttings norizontnlly p~~nted
were nearly twice tt~D6€ of t hQ vertioe.l ODes.
7. The number of new formed bulblets on a b.orizon~~l cutting
wes m>illY time s as mucn as t b.OOe carried on e. v e rt teal one.
The concentration of IAA in this respect was 100 F.F.m.
8. The heaviest weight of new formed bulblets was obt~ined
from horizontal cuttings tre~ted with IAA ~s 200 F.~.m.
9. IBA had more influence on the development of new
bulblets on the vertically pl~nted cuttings. The suit~blG
concdntration wa.s 100 and 200 p.p.m.
10. Pre-treAtment of cuttings with rootone aur,t st s concentrgt10n
of 2000 F.F.m. remarkably increased the percentagos
of the survival cuttings of both vertioal ~d hDrizont~l
planting.
11. Rootone application inereased the number ~f bulblets
par cutting, their weights and diamuters espocially ’,~ith
vertical cutting-
12. Wounding significantly 1ncre~so. tho percentage of
survival Bea.les, number, weights and diamoter of bulblota
form~d on the scale.
13. Storing the bulbs at 100e, before wound trG~tment was
effective for better qu~lityof bulbs butt if qu~ntity of
bulbs is the 80im , storing at room temperature is :i.deal.
14. For higher produ0tion ;)f bu1.blets, IAA may be appliod

15. The ti’eF-~tment of lBA is depcn6ant on the pr-ovd cu a
