　　为了探明钼对小麦种子萌发及幼苗生长的生理和结构效应，以不同专用小麦品种为材料，研究了不同浓度钼对小麦种子淀粉酶活性、发芽势、发芽率、根系活力、根尖结构、幼苗生长的影响。结果表明：低浓度钼处理液对小麦种子发芽势和发芽率有促进作用，其中以10 mg/L促进效果最佳，高浓度有明显的抑制作用，这与钼影响种子淀粉酶活力相一致；小麦根系活力、根长、芽长、根重和芽重随钼浓度的升高呈现先促进后抑制变化趋势，但根比芽对钼敏感；一定钼浓度能促进根尖分生区细胞体积变大和数量的增多，但分生区不同部位对浓度响应有差异；不同专用小麦对不同钼浓度响应有别，品种对钼反应敏感表现为中筋小麦‘扬麦16’>弱筋小麦‘扬麦19’>强筋小麦‘罗麦8号’。

To prove up the physiological and structural effects of molybdenum on wheat seed germination and seedling growth, the wheat varieties for different uses were chosen to study the effect of the different molybdenum concentration on the activities of amylase, bud potentials, germination rate, activities of roots, structure of root tip and seedling growth. The results were as followings, low concentrations (10 mg/L) accelerated bud potential and germination rate, while high concentrations restrained them, this was corresponding to activities of amylase in wheat under the same molybdenum treatments. The activities of roots, root length, bud length, root weight and bud weight took on a trend of increase first and then decreased, root length and weight were more sensitive to molybdenum than bud. A certain molybdenum concentrations could advance volumes and quantities of meristematic cells in root tip. The different wheat varieties for different uses were different response to molybdenum as follows:‘Yangmai 16’with medium gluten >‘Yangmai19’with weak gluten>‘Luomai8’with strong gluten.
