已知,在小麦灌浆期叶片不仅向穗输送光合产物,而且将氮、磷、钾等无机成分再运转到籽粒中。一般认为,这些无机成分与光合产物一起由叶经筛管输送的。但有报道,无机成分未必通过筛管流入籽粒。为研究小麦无机成

It is known that during the grain filling stage of wheat, photosynthetic products are not only transported to the ear, but also inorganic components such as nitrogen, phosphorus and potassium are re-run into the grain. It is generally believed that these inorganic components are transported with the photosynthate by the leaf screens. However, it has been reported that inorganic components do not necessarily flow through the sieve tube into the grain. In order to study inorganic wheat into
