我们研究了原丰早幼穗发育和植株形态的相关生长,并作了总结,以期为制定栽培技术提供依据。试验于八○年进行。四月二十日播种,五月二十八日单本移栽300株,以第六叶为基数,每株点漆观察叶龄。从穗分化开始前夕起,每隔一日拔取一定数量的稻苗,采取单株从外到内分层剥查观测的方法,首先测定主茎叶龄余数,节间数及每节间长度、叶鞘等伸长状况并摄影,随后用不同仪器和不同方法观察穗的发育。在花粉母细胞形成前各发育时期,用双目解剖显微镜和配套解剖显微镜剥查观察并摄影。从花粉母细胞形成期开始至花粉充实完成期,先用固定液固定材料,然后取幼穗中上部花药用醋酸洋红染色制片,并用石腊封存,再用高倍显微镜(1500
We studied the correlation between the growth of panicle and panicle morphology in early harvest, and summarized the results in order to provide the basis for the development of cultivation techniques. The test was carried out in 1980. April 20 planting, May 28 single transplanting 300, the sixth leaf as the base, each plant point to observe the leaf lacquer. From the beginning of spike differentiation, a certain amount of rice seedlings were taken every other day, and the stratified stripping observation was conducted from the outside to the inside of the plant. The remnants of leaves, the number of internodes and the length of each node were measured. Leaf sheath and other elongation and photography, followed by different instruments and different methods to observe the development of the ear. Pollen mother cells before the formation of each developmental period, with a bi-directional anatomical microscope dissection microscope and stripped observation and photography. From the beginning of the formation of pollen mother cells to the completion of pollen enrichment, the material was first fixed with a fixing solution, and then the upper anthers of young ears were taken and dyed with paraffin, and then photographed with high magnification microscope (1500
