硅对水培大蒜生长和生理特性的影响
Effects of Silicon in Nutrient Solution on Garlic Growth and Its Physiological Characteristics
摘要
Abstract
‘Jinxiangbaipisuan’ was taken as experiment material investigate the effects of silicon on root growth,photosynthetic characteristics and yield of hydroponics cultured garlic(Allium sativum L.). Five different silicon levels (0,0.75,1.50,2.25,3.00 mmol·L-1) were designed. The results showed that the root system growth,fresh weights of garlic plant,bolt and bulb,and root system activity all rose with the increase of silicon concentration from 0 to 1.50 mmol·L-1,but fell while the silicon content reached 1.50 mmol·L-1. At the same time,the pigment content,net photosynthetic rate and stomatal conductance of leaves also increased first and then decreased with the increase of silicon content from 0 to 3.00 mmol·L-1.They reached the highest when silicon concentration was 1.50 mmol·L-1. While the change trend of transpiration was just the opposite. It reached the minimum value at Si 1.50 mmol·L-1 and was reduced by 17.78% compared with the treatment without silicon.关键词
