1. In the anther of the rice of male fertility, between two anther chambers that lie at the connective bilateral edge, two "tissue spaces between two anther chambers" are formed beneath the epidermis at the bottom of the concave places. They both get through the bilateral edge of the anther longitudinally. The mature anther has a fibrous layer of cells.

1. In the anther of the rice of male fertility, between two anther chambers that lie at the connective bilateral edge, two "tissue spaces between two anther chambers" are formed beneath the epidermis at the bottom of the concave places. They both get through the bilateral edge of the anther longitudinally. The mature anther has a fibrous layer of cells. On the two ends of the anther and between the two anther chambers in the concave places, the cell walls of the fibrous layer produce strong annular secondary thickened strips which are oriented perpendicularly to the circumference, and which connet transversally with each other, thus making up respectively a "spring" on the partial walls (circumference) of the two anther chambers. The same end of the two "springs" respectively connects with the two lateral edges of the "tissue space between two anther chambers". The strong "spring" and the "tissue space between two anther chambers", when they exist simultaneously, are the inner factors of the opening of the anther.2. The failure for the anther of male sterile lines in rice to open is due either to the non-existence of the "tissue space between two anther chambers", or to the formation of very weak "springs".3. Secondary thickened indensity on the cell walls of the fibrous layer of the concave places between the two anther chambers, become weaker and weaker from the two ends of the anther to its central parts and in the central place no secondary thickness is formed. This tissue structure has decided the orders of the longitudinal slits of the anther, which begin at the two ends and then the slits extend to each others central parts till their complete opening.4. When conditions are not suitable, there will appear a part of anthers of male sterilily in some hybrids of rice.

1.雄性能育水稻的花药,位于药隔两侧的各两药室间凹陷部位底部的表皮细胞下形成两个“药室间组织间隙”,它们纵贯花药两侧。成熟花药具纤维层细胞;在花药两端两药室间凹陷部位上的那些纤维层细胞壁,沿垂周方向产生强烈的环状次生增厚条纹,它们横向地互相连接而分别在两药室的那段壁(圆周)上各自形成一条“弹簧”,两条“弹簧”的同一端分别和“药室间组织间隙”的两侧边相连;强劲的“弹簧”与“药室间组织间隙”二者同时存在是水稻花药开裂的内因。 2.雄性不育水稻花药不开裂,或者是由于无“药室间组织间隙”的存在,或者是由于形成很微弱的“弹簧”。 3.在两药室间凹陷部位上的那些纤维层细胞壁上次生增厚的强度,由花药两端向中部逐渐减弱,终至中部不产生次生增厚。这种组织结构决定了水稻花药开裂的顺序是两端先开裂,裂缝由两端向中部延伸,直至完全开裂。 4.当条件不适宜时,某些杂种水稻会出现部分雄性不育的花药。

Within prper sowing date,the coleoptile nede began to tiiler following 20 d petorior to barleyseedling emergence. The tillering time of semi-winter varieties(included weak spring varieties)Iastad about 66~75d. Tillering time and offective tillering time amounted for 37%~42%and 13%~19% of life span respective-ly ,Among rates of the fertile ear number of various levels of tillers versus the total fertile ear number, the mainears amounted for 26%~27%,the primary tillering ears amounted for 39%~60%,of whicb both lst and 2ndtillering ears amounted for 33%~58%. The variety, whose tillering ability was intermediate and fertile ear ratewas high, shoule be choosed to realize the high-yielding obju=ective. In cultivation, it was necessary to apply basefertilizers sufficiently, stimulate vigorous seedling to germinate early, inhibit the secondary and tertiary ears to mul-tiply,coordinate the favorable development relation between the individual plant and population.

在适宜播期范围内,大麦出苗后20d左右,芽鞘节就开始分蘖。半冬性品种(包括弱春性品种).其分蘖期约66~75d,占全生育期的37%~42%,其中有效分蘖期占13%~19%。各级分蘖的成穗数占总成穗数的比值,主穗占26%~27%,一级蘖穗占39%~60%,其中Ⅰ和Ⅱ蘖成穗占33%~58%。为了实现丰产目标,应须选育分蘖力中等,成穗率高的品种。栽培上要求施足底肥,促壮苗早发,控制二、三级分蘖滋生,办调好个体与群体问的发育关系。
