不同LED光谱和辐照度耦合对刺参生长及生理功能的影响
Effects of different LED spectra and irradiance on the growth and physiological function of Apostichopus japonicas
摘要
Abstract
In order to explore the suitable light conditions of Apostichopus japonicus in indoor culture,1 680 juvenile sea cucumber(weight 0.185±0.014 g)were placed in three irradiance(1 000 mW/m2,2 500 mW/m2,4 000 mW/m2)in the environment of red(R)、full spectrum(W)and dark(D)for 35 days.The results showed that different spectra and irradiance could significantly affect the growth and physiological function of juvenile sea cucumber.The body weight of the red light 4 000 mW/m2 group was significantly higher than that of the full spectrum 4 000 mW/m2 group(P＜0.05).The body length of the red light 1 000 mW/m2 group was significantly higher than that of the full spectrum 4 000 mW/m2 group(P＜0.05).The specific body weight growth rate of the red light 1 000 mW/m2 group was significantly higher than that of the full spectrum 4 000 mW/m2 group(P＜0.05).The survival rate of the red light 4 000 mW/m2 group was significantly higher than that of the full spectrum 4 000 mW/m2 group(P＜0.05).For enzyme activity,amylase(AMS)activity was the highest in the red light 4 000 mW/m2 group and lipase(LPS)activity in the red light 2 500 mW/m2 group.The activities of acid phosphatase(ACP)and alkaline phosphatase(AKP)in the red light 4 000 mW/m2 group were significantly higher than those in the red light 1 000 mW/m2 group(P＜0.05).The catalase(CAT)activity was the highest in the full spectrum 2 500 mW/m2 group.The activity of superoxide dismutase(SOD)was the highest in the red light 4 000 mW/m2 group,which was significantly higher than that in the full spectrum 1 000 mW/m2 group(P＜0.05).In summary,it is recommended to use red light to cultivate juvenile sea cucumber in an indoor culture environment and control the irradiance at 1 000-4 000 mW/m2.In this study,the effects of three irradiance degrees on the juvenile sea cucumber were studied,and the results showed that the growth performance of the juvenile sea cucumber with red light of 1 000-4 000 mW/m2 was better.In order to accurately and optimally determine the most appropriate irradiance,a fine irradiance gradient was recommended to further evaluate the effect of irradiance on the juvenile sea cucumber.关键词
