吸附类2种藤本植物对攀附面和干旱胁迫的生长响应
Effects of Drought Stress and Climbing Surfaces on Growth of 2 Adhering Vines
摘要
Abstract
To study the growth differences and adaptation strategies of grass and woody vines under drought stress and different climbing surfaces,the potted seedlings of Piper hancei and Syngonium podophyllum were used as experimental materials,and 3 kinds of climbing surfaces were set up without support for climbing,and the climbing growth status and variation of plants on different climbing surfaces under normal watering and drought stress were analyzed.The results showed that in terms of aboveground morphology,the aerial root growth of 2 li-ana species was significantly affected by water under drought stress,and the length and number of aerial roots were the smallest in drought and no support treatment;compared with the treatment without support,the stem length of P.hancei showed a significantly higher on the brick wall surface,and the aerial root length of the S.podophyllum was significantly higher than that on the other climbing surfaces.In terms of root morphology,both species had higher root length and root tip number in the normal watering concrete surface treatment;in the non-support treatment,the root morphological indexes of P.hancei were the smallest.In terms of biomass,the aerial biomass and total biomass of 2 plants also showed different degrees of decline during drought stress,the root bio-mass was improved.And the stem and petiole biomass of S.podophyllum had significantly higher in the normal watering brick wall treatment.Under normal moisture,both lianas had higher above-ground biomass.But in the absence of supports,the investment in underground root system was increased to promote growth,and the total biomass of P.hancei on the concrete surface was twice that of the non-supports.关键词
