Regularity in Variation of Leaf Color and Nitrogen Distribution in Half-Leaf Blades by Leaf Position on the Stems of Rice Plants:II. Uneven translocation of nitrogen between outside and inside half-leaves
Chlorophyll meter value Distribution Half-leaf blade Leaf blade width Nodal root Translocation

We have reported in a previous paper that the outside half-leaf had a smaller volume and deeper leaf color than the inside half-leaf. The half-leaf color was not dependent only on the difference in le...

摘要
利用细胞学、染色体C分带和原位杂交方法,对八倍体小黑麦劲松49与八倍体小滨麦杂种后代选育的稳定遗传材料山农030-1进行了鉴定。染色体观察结果表明,山农030-1根尖染色体数目为42,花粉母细胞减数分裂中期I(PMC MI)染色体构型为2n=21Ⅱ。分别以黑麦、滨麦草基因组DNA为探针进行原位杂交,表明山农030-1含有一对黑麦和小麦的整臂易位染色体,不含有来自滨麦草的遗传物质。染色体C分...
