摘要

目的

研究接种不同根际促生菌剂（PGPR）对滇重楼幼苗的生长发育和入药品质的影响，为培育优质滇重楼药材提供参考。

方法

通过室温盆栽接种试验方法，采用单因素完全随机设计，研究了5种不同PGPR对滇重楼生理特性及无机元素的影响。

结果

接种外源不同PGPR可以不同程度地促进滇重楼的生长发育，延缓叶片的衰老，提高新根茎和老根茎的药用价值。其中，与未接种空白相比，外源接种复合微生物菌肥（FH）和三炬灌金液（SJ）可以增加根系活力及叶片内光合色素含量，增强叶片内的抗氧化酶活性［超氧化物歧化酶（SOD），过氧化氢酶（CAT）和过氧化物酶（POD）］，减少叶片中丙二醛（MDA）的产生，其减少幅度依次为10.46%~39.62%和20.99%~53.12%，随着生育进程的推进，MDA的抑制率逐渐增加，这有效地延缓了滇重楼叶片的衰老。此外，外源接种不同PGPR可以不同程度地增加新根茎和老根茎内营养元素含量，降低重金属元素含量，提高了滇重楼根茎的药用价值。

结论

FH和SJ对滇重楼幼苗生长的促进作用及根茎药用价值的调控效果最佳，为PGPR在滇重楼上的应用推广提供了参考依据。

Abstract

Objective

To study the effects of different plant growth-promoting rhizobacteria （PGPR） on the growth of

Paris polyphylla

var.

yunnanensis

seedlings and the quality of its medicinal parts， in order to provide reference for the cultivation of high-quality

P. polyphylla

var.

yunnanensis

Method

The pot culture experiment at room temperature and the single-factor completely random design were employed for exploring the effects of five PGPR on physiological characteristics and inorganic elements of

P. polyphylla

var.

yunnanensis

Result

The results showed that the exogenous inoculation of different PGPR promoted the growth and development of

P. polyphylla

var.

yunnanensis

to varying degrees， delayed the senescence of leaves， and improved the medicinal value of new and old rhizomes. Compared with the non-inoculated control， the exogenous inoculation of compound microbial fertilizer （FH） and microbial agent Sanju Guanjin liquid （SJ） enhanced the root vigor， increased the content of photosynthetic pigments and the activities of anti-oxidant enzymes ［superoxide dismutase （SOD）， catalase （CAT）， and peroxidase （POD）］， and reduced the content of malondialdehyde （MDA） in leaves. Their inhibition rates against MDA were 10.46%-39.62% and 20.99%-53.12%， respectively. With the growth of

P. polyphylla

var.

yunnanensis

， the inhibition rate against MDA gradually increased， which effectively delayed the senescence of

P. polyphylla

var.

yunnanensis

leaves. In addition， the exogenous inoculation of different PGPR promoted the accumulation of nutrient elements in new and old rhizomes， lowered the heavy metal content to varying degrees， and improved the medicinal value of

P. polyphylla

var.

yunnanensis

rhizomes.

Conclusion

FH and SJ have exhibited the best promoting effect on the growth of

P. polyphylla

var.

yunnanensis

seedlings and also the best regulatory effect on the medicinal value of

P. polyphylla

var.

yunnanensis

rhizomes， which has provided reference for the application and promotion of PGPR in the growth of

P. polyphylla

var.

yunnanensis
