比较了三种由雌性单株建立蓖麻雌性系方法：（１）利用环境高温处理 ＮＥＳ型雌性单株诱导雄花建立雌性系，是比较成熟的方法，但对日均温要求较高。 （２）利用植物生长调节剂处理 ＮＥＳ型雌性单株诱导雄花建立雌性系，该法成功的 可能性较大，对环境条件要求也不高，如积极探索有望早日成为比较成熟的方法， 目前已有一定的进展。（３）利用组织培养无性繁殖Ｎ型雌性单株建立雌性系，该 法也有一定的可能性，值得进一步探索。
Three methods of establishing castor line from female plants were compared: (1) The establishment of female line by inducing male flowers with NES type under high temperature environment is more mature method, but the daily average temperature is more demanding. (2) The use of plant growth regulators in the treatment of NES-type female plants to induce female flowers to establish female lines is more likely to be successful and less demanding on environmental conditions, such as positive exploration is expected to become a relatively mature method as soon as possible There is some progress. (3) The establishment of female lines through tissue culture of N type female plantlets is also a possibility that is worth further exploration.
