为了研究生长素在水稻根负向光性反应中的作用 ,用含有IAA的琼脂块贴附在种子根的根尖表面观测IAA对根的生长效应 ,用ELISA法测定根尖的IAA含量 ,并对种子根弯曲部分进行半薄切片 ,结果表明 :(1)种子根的生长方向既受光的调控也受外施的IAA的调控 ,根尖向贴有含IAA琼脂块的一侧弯曲生长 ;(2 )不定根在光照 1。
In optical mineralogy, the relative magnitude of ( N g- N m) and ( N m- N p) are often used to the discrimination of optically positive biaxial crystals from optically negative ones.
它们之间的关系如果是Ｎｇ－Ｎｍ＞Ｎｍ－Ｎｐ时，矿物为正光性；反之，则为负光性。
