Abstract
Effects of seed soaking with alkaloid extracts from Peganum multisectum Bobr on seed germination, seedling growth and some physiological characteristics of wheat (Triticum aestivum L.) under the condition of indoor culture and soil culture in flowerpot were investigated. The results showed that when wheat seeds were soaked with extracts of total alkaloid, water-soluble alkaloid and fat-soluble alkaloid from P. multisectum, the respiratory rate, activities of amylase and proteinase during seed germination and germination rate were inhibited significantly, germination rate reduced with concentration of alkaloid extract increased. However, they significantly increased the root vigor, chlorophyll content and the activities of nitrate reductase (NR), superox- ide dismutase (SOD) and peroxidase (POD) in leaves of wheat seedlings during seedling growth, but inhibited catalase (CAT) activity, the root volume, shoot height and dry weights of root and shoot increased. The effects of alkaloid extract from P. multisectum on the germination and seedling growth of wheat were: total alkaloid water-soluble alkaloid fat-soluble alkaloid.
