(2)In general the root length of wheat and root/shoot ratio(R/S) arose when the Pi supply was deprived, however, the change models differed among different wheat genotypes: In tested varieties, Chinese spring and Zhou-mai 18 respond to phosphate stress more slowly, Tai-kong 6hao、Yu-nong 202、Yan-zhan 4110
(2)在水培条件下,不同基因型小麦对磷饥饿胁迫的反应总体上表现在根系长度和根冠比所提高,但不同基因型小麦的反应特点有差异即在供试品种中,中国春和周麦18对磷饥饿做出的反应较为迟缓,而太空6号、豫农202和偃展4110则在较早时间对磷饥饿做出发育水平反应,随后呈现平台趋势;值得注意的是郑麦9023在对磷饥饿较早做出形态适应反应后出现明显恢复,暗示其可能存在某种显著的补偿机制。

05mg/g时,玉米幼苗的根长、根冠比(R/S)、WUE呈升高趋势;当钇用量在干土中的浓度为0。
3) root shoot ratio
根冠比
1.
The root shoot ratio of the treated seedlings was raised to 109%-157%, the combined water content was enhanced, the free water content in leaf tissue was lowered and thus increased the ratio of the above two to 0.
结果表明 ,在大十字期喷施S330 7可以抑制烟苗节间的伸长 ,降低烟苗株高 ;烟苗的根冠比提高10 9%～ 15 7% ;降低烟苗叶组织中自由水含量 ,提高束缚水含量 ,束缚水与自由水的比值增加0 。

通过对不同水份条件下防风幼苗的根冠比、根粗和根重三项形态指标及幼苗中丙二醛、可溶性糖及叶绿素含量三项生理指标的测定,证明了在以甘南县为代表的黑龙江省西部半干旱气候条件下,防风幼苗在降水量超过40mm情况下可以正常生长。
6) R/S
根/冠比
1.
The results of the trial indicated that rape fresh weight and root weight have been enhanced markedly by applied city sludge, applied city sludge was beneficial to optimize rape R/S; and rape uptake of N,P,K were increased by applied city sludge.
结果发现:适宜的污泥用量可显著提高盆栽油菜的生物量和根重,并有助于盆栽油菜根/冠比指标的优化;同时,污泥施用比化肥更能促进盆栽油菜对N、P、K元素的吸收,能有效提高这些营养元素的利用效率;但当污泥用量达到6g/kg土时,污泥对盆栽油菜产量提高的促进作用会明显降低。
