(南京农业大学杂草研究室, 南京 210095)
摘 要: 在实验室和温室条件下, 用从石菖蒲根茎中提取的挥发油经减压蒸馏获得的组分四, 对稗草、鳢肠和水稻
的萌发与生长进行了生物学效应测试。结果表明, 在低浓度时促进供试植物的萌发和生长, 而在高浓度时则抑制萌
发和生长。实验室培养皿条件下, 50~ 400 m göL 浓度抑制作用产生并逐渐增加, 400 m göL 以上达到 90% 或更高。
但是, 温室盆钵条件下, 3 000 m göL 时才出现抑制作用, 在 1 000 m göL 以下均表现促进作用。

2 Results and D iscussion
A t the concen tra t ion of 50 m göL , the ex tract
p romo ted germ inat ion of the seeds of rice, barn2
yardgrass and eclip ta. T here w ere tw o peak s oc2
cu rred at 50 m göL and 300 m göL in the germ ina2

steep change occu rred tw o t im es in the cu rves of
a ll of th ree tested species betw een 50 m göL
and 100 m göL and betw een 300 and 400 m göL
(F ig11). How ever, barnyardgrass on ly had one
peak at 50 m göL and as concen tra t ion of ex tract in2
creased to greater than 50 m göL , germ inat ion of
the seeds w as inh ib ited. T here w as a fla t cu rve fo r
barnyardgrass betw een 100 m göL and 300 m göL
(F ig. 1). Ex tract so lu t ion at 500 m göL reduced the
ra te of germ inat ion dow n to abou t 50% fo r all test2
ed p lan ts.
F ig11 T he effect of ex tract on germ ination rate of
the seeds of tested w eeds and rice
How ever, there w ere differences in b io logica l
act ivity on germ inat ion of th ree species of seeds.
Betw een 100 m göL and 300 m göL , the germ inat ion
ra te of rice seeds w as no t m arkedly influenced by
the ex tract, w h ile that of eclip ta go t h igh po in t a t
300 m göL.
Since the essen t ia l o il ex tracted from roo ts of
A corus ta ta rinow ii can be u sed as repellen t again st

W hen concen tra t ion w as 500 m göL grow th w as
comp letely inh ib ited. T he steep cu rves occu rred
betw een 50 m göL and 100 m göL. T he sm all peak
appeared at 50 m göL in rice (F ig. 2). T he ex tract
retarded the roo t grow th m uch mo re than stem

increased to 400 m göL , the roo t grow th nearly
stopped ( F ig. 3 ). T herefo re, the resu lt show ed
that the inh ib it ion of ex tract to roo t grow th w as

w h ich ex tract shou ld be studied fu rther to deter2

F ig14 T he effect of ex tract on the grow th of seedlings
of tested w eeds and rice
T he num ber of roo ts w as no t sign if ican t ly in2
f luenced at concen tra t ion of less than 400 m göL
(P > 0. 05) (F ig. 5). A t 400 m göL , the num ber of
roo ts reduced to the low est percen tage. How ever,
there w ere differences in b ioact ivity betw een tho se
th ree species of p lan ts since there w ere m arked
differences betw een rice and barnyard grass a t
concen tra t ion of betw een 400 m göL o r h igher and
300 m göL o r low er fo r (P < 0. 01). A lthough the

under the trea tm en t of 300 m göL ex tract w ere

on ly had bud sheath ou t of seeds ( F ig. 5 ). It
appears that bud sheath cou ld no t be inh ib ited by
the ex tract. T he elongat ion of bud sheath cou ld be
even p romo ted at 300 m göL o r h igher concen tra2
t ion.
T he grow th of tested p lan ts w as p romo ted at

h igher, the grow th of p lan ts w as in h ib ited. T he
inh ib it ion effect of the ex tract on the grow th of
barnyardgrass and eclip ta w as greater than that on
rice.
F ig16 T he effect of ex tract on grow th of the w eeds

T he inh ib it ion effect of ex tract on tw o w eed
