1) individual fertility
单株育性
1.
Peiai64S,AnnongS-1and 5460S were used to observe the individual fertility,The results showed that except AnnongS-1,the highly significant difference of fertility among florets of a plant was found in other seven male sterile lines.
以农垦58S,7001S,5047S,W6154S,KS-9,培矮64S,安农S-1和5460S等不同类型的水稻光温敏核不育系为材料,对单株育性的表现进行了观察,结果表明:除安农S-1外,其它7个不育系株内颖花间育性均存在显著差异,连续套袋自交对降低颖花间的育性差异效果不大;不育期间有少量自交结实,结实粒在穗上的分布是随机的,它们具有与相应不育系一致的光温敏核不育特性。
3) individual plant propagation
单株繁育

5) yield of individual plant
单株性状
6) male sterile plant
雄性不育株
1.
Studies on the change of callose and spro pollenin during the development of microsporangium cells of the male sterile plant and male fertile plant in Cunninghamia lanceolata .
对杉木雄性不育株与可育株在小孢子发生和发育过程中的小孢子囊内各种细胞的胼胝质和孢粉素的变化进行研究,结果表明:杉木雄性不育株的小孢子囊发育迟缓,其败育可分为:无小孢子囊型、减数分裂Ⅰ前中层细胞增生型和减数分裂Ⅰ后中层细胞增生型等3种;其细胞壁厚薄不均,在其小孢子囊发育过程中,细胞内淀粉粒缺乏或异常;在早期,其胼胝质壁较可育株的薄,发出的荧光较弱;发育后期,则具有胼胝质壁,直至细胞解体。

茶树单株选择
individual selection of tea plant
茶树单株选择(individual seleetion oftea Plant)茶树选择育种法之一。又称茶树系统选择或茶树个体选择,即从现有茶树群体品种或育种材料中,根据育种目标.选出一定数量的优良个体,分别进行扦插繁殖,然后通过品比试验,从而育成新的茶树品种的方法。单株选择方法简单,效果显著,是最常用的茶树育种方法。国内外许多茶树新品种,多数都是采用此法育成的。OQQ皿命。户。喊只 ,协.,、护口,才,尸、 I矛尚画┌────┐│乡礴黔 │└────┘ ┌──┐ │‘奋│ │命 │ │Q │ │石户│ │Q │ │戈奋│ └──┘ 尹 ︸碗.︸‘l咬峨心嵘叹< r..﹄L‘ 护l由回回图┌─────┐│户.产产, ││严产严 ││严产,尸 ││严严严 ││尹.加尹, ││声.产,产.│└─────┘┌──────┐│l。尸尸 ││声,产,产,││产,严声, ││声,严户 ││户严尸 ││产,尸尸 │└──────┘ 茶树单株选择图式 由上至下:1.第l年从原始群体中选择优良植株2.第2~3年分株初步繁值,并继.续鉴定入选单株3.第3~10年比较试脸(右第1行为对照品种),同时进行区城性试脸4.第10年以后良种繁殖推广 (刘祖生)
