摘要

本文研究了壳聚糖对水培木薯营养器官生长和过氧化物酶活性的影响。实验是在生态研究中心(Côte d’ivoire)的自然光照明的温室下进行的。在4个木薯品种(Yace、9620A、TMS4(2)1425和TMS30572)的培养基中添加了6种浓度的壳聚糖(0、25、50、75、100和125 mg L -1)。这些培养基每15天更新一次,植株的生长持续了两个月。结果表明,壳聚糖对不同品种和不同器官的生长有1.1 ~ 1.4的促进作用。壳聚糖浓度为75或100 mg L -1时,不同品种的叶片和根系过氧化物酶活性提高1.5 ~ 2.6倍。该活性在紫花苜蓿叶片和根部分别乘以2.3 ~ 2.6,TMS30572乘以2.6和1.5,TMS4(2)1425乘以1.9和2.2。在9620A中,这个因子小于2。这些结果表明,壳聚糖可以作为木薯的生物刺激剂。

Effects of chitosan on vegetative organs growth and peroxidases activities in cassava (Manihot esculenta Crantz) cultivars YACE, 9620A, TMS4(2)1425 and TMS30572
In this work, the influence of chitosan on vegetative organs growth and peroxidases activities in cassava (Manihot esculenta, Euphorbiaceae) plants grown in hydroponic was studied. The experiment was carried out under a greenhouse lit by natural light at the Ecology Research Center (Côte d’Ivoire). Six concentrations of chitosan (0, 25, 50, 75, 100 and 125 mg L -1 ) added to the culture media were tested on four cassava cultivars (Yace, 9620A, TMS4(2)1425 and TMS30572). These media are renewed every 15 days and growth of the plants lasted two months. The results showed that chitosan stimulated the growth of 1.1 to 1.4 according to cultivars and organs. Peroxidases activities were 1.5 to 2.6 times higher in leaves and roots in presence of 75 or 100 mg L -1 of chitosan depending on the cultivars. This activity is multiplied by 2.3 to 2.6 respectively in leaves and roots of Yacé, 2.6 and 1.5 of TMS30572, 1.9 and 2.2 of TMS4(2)1425. In 9620A, this factor was less than 2. These results show that chitosan could be a biostimulator in cassava.
