据国外报道,印度旁遮普农业大学用茎节繁殖水稻成功。这种无性繁殖新方法的成功,引起了农业工作者的极大兴趣。茎节繁殖采用印度栽培品种PR106的50个分蘖。在枝节抽穗期间,截取其较上四个茎节的一部分,每个节两端留3厘米,垂直插在湿润的泥盆里。结果看出,所有与土壤接触部分都能长出根来,并再生出有根系 According to foreign reports, India’s Punjab Agricultural University successfully breed rice with stems. The success of this new approach to asexual reproduction has drawn great interest among agricultural workers. Stems were propagated using 50 tillers of Indian cultivar PR106. During the heading of a branch, cut its part from the upper four stems, leaving 3 cm at each end of each node, plunged vertically into a moist clay pot. The result shows that all the parts in contact with the soil can grow roots and regenerate the root system
