摘要
研究了不同基质配比对"珍珠"南瓜的叶绿素含量,硝酸还原酶活性及过氧化物酶的活性的影响。结果表明:在植株生长中期,每个处理的叶绿素的含量都是最高的,其中处理B(珍珠岩∶蛭石∶菇渣=2∶1∶3)和处理D(炉渣∶蛭石∶泥炭=2∶1∶3)的南瓜植株的叶绿素含量较多;硝酸还原酶的活性也是在植株的生长中期出现了最高值,其中处理B(珍珠岩∶蛭石∶菇渣=2∶1∶3和处理D(炉渣∶蛭石∶泥炭=2∶1∶3)的南瓜植株的硝酸还原酶活性较高;过氧化物酶的活性在植株的生长中期最低,其中处理A的活性最低。因此处理D、处理B的基质配比较适合观赏南瓜"珍珠"的生长。
This experimental studied the effects of different proportion of substrates on chlorophyll content,NR and POD activity of Pearl pumpkin.The results indicated that during the middle growth stage,the chlorophyll content of all treatments was high,of which treatment B(Pearlite∶Vermiculite∶Mushroom Residue=2∶1∶3)and treatment D(Slag∶Vermiculite∶Peat=2∶1∶3)were highest.During the middle growth stage,NR activity was maximum,of which treatment B and treatment D were higher and the POD activity was lowest,of which treatment A was lowest.So the treatment B and D,were suitable to the pearl pumpkin.
