在一个低温年分,我们在玉米田发现大量幼苗变成紫红色,持续二十余日,秋季亩产仅462.3斤(通常可达700—800斤)。我们对此进行了初步的调查研究。一、紫苗与绿苗(正常苗)在形态上的差异紫苗,苗色紫红,叶片直立,茎圆叶窄;健壮苗却是叶色浓绿,茎扁叶宽。紫苗的生长发育明显地落后于正常苗,其苗龄和株高都低于正常苗,干重仅为正常苗的53.8％。紫苗的根系发育也比正常苗弱,根系的排水量和干重
In a year of low temperature, we found that a large amount of seedlings in maize fields turned into fuchsia for more than 20 days. In the autumn, only 462.3 kg (usually up to 700-800 kg) were produced per mu. We conducted a preliminary investigation of this. First, the purple seedlings and green seedlings (normal seedlings) in the morphological differences Purple seedlings, seedling purple, leaves erect, stems round leaves narrow; healthy seedling is dark green leaves, stems flat leaf width. The growth and development of the purple seedling obviously lag behind the normal seedling, its seedling age and plant height are lower than the normal seedling, the dry weight is only 53.8% of the normal seedling. Purple seedling root development than normal seedlings, root drainage and dry weight
