不同栽植处理对梭梭幼苗气孔形态及解剖结构的影响
The Effects of Different Planting Treatments on Stomatal Morphology and Anatomical Structure of Haloxylon ammodendron Seedlings
摘要
Abstract
Haloxylon ammodendrom is an excellent tree species in northwest China for windproof/prevention,sand fixation,and ecological balance protection.However,the dry climate and high summer temperatures in the arid desert areas of northwest China severely affect the growth and development of H.ammodendrom seed-lings.To explore the suitable planting methods for the growth of the seedlings,this study used 1-year-old H.ammodendron seedlings as experimental subjects and set up 5 different doses of super absorbent polymers(0 g,1,2,3,4 g)and 4 planting depths(20,40,60,80 cm)for combination treatments.The changes in stomatal morphology and anatomical structure of H.ammodendron after different planting treatments were studied.The results showed that with the increase of water retaining agent dosage and planting depth,the stomatal length,stomatal width,stomatal area,and thickness of various anatomical structures of the seedlings showed a trend of first increasing and then decreasing.The pore density shows a trend of first decreasing and then increasing.Sto-matal length,stomatal width,stomatal area,diameter of assimilating branch,stratum corneum,palisade tissue,water storage tissue,vascular column thickness,and duct aperture were all the largest,while stomatal density was the smallest when treated with 3g super absorbent polymer and 60cm planting depth.The applica-tion of suitable planting treatments can create a better growth environment for H.ammodendron.When facing environmental stress,it can improve plant stress resistance and effectively alleviate the impact of stress on plants.关键词
