Methyl jasmonate (MeJA) can induce flowering habits. In order to further elucidate the regulatory role of MeJA on the flowering habits, lodicule morhpology, and outcrossing seed setting rate of photo-thermo sensitive male sterile lines of wheat, this study immersed the wheat line BS141 with 4 mmol·L-1 MeJA at 2 days post-anthesis, using water-immersed spikes as a control. The effects of MeJA on the daily anthesis rate, temporal variations in flowering, the glume opening rate, anthesis angle, lemma morphology, and outcrossing seed setting were investigated. The results demonstrated that upon treatment with MeJA, the glume opening rate of the BS141 peaked on the day of treatment, showing an increase of 31.45 percentage points compared to the control group. However, starting from the second day, this number was significantly lower than that of the control. From the fourth to the fifth day, there was no significant difference compared with the control. Pollination at the time when the glume opening rate was the highest increased the outcrossing seed setting rate of BS141 by 24.77 percentage points compared with the control. The peak flowering period of the MeJA-treated BS141 was predominantly concentrated at 13:00, whereas the control was more dispersed. The stigma exsertion rate of BS141 was statistically analyzed at 10:00 a.m. It was found that the stigma exsertion rate of BS141 treated with MeJA was lower than that of the control within 5 days. The overall maximum daily opening angle of BS141 treated with MeJA was lower than that of the control group. Therefore, by spraying exogenous MeJA, the glume opening rate of wheat photo-thermo sensitive male sterile line could be maximized on the day of spraying, and the flowering peak was relatively concentrated. At this time, pollination could significantly increase the outcrossing seed setting rate. However, spraying MeJA had no significant effect on the stigma exsertion rate and the maximum opening angle.

茉莉酸甲酯(MeJA)可以诱导作物开花习性。为进一步明确MeJA对小麦光温敏雄性不育系开花习性、浆片及异交结实的调控作用,于花后第2天对小麦光温敏雄性不育系BS141进行4 mmol·L-1MeJA浸穗处理,同时以浸水穗作为对照,研究MeJA对不育系每日开颖率、日不同时间开花变化、柱头外露率、开颖角度、浆片形态及异交结实的影响。结果表明,MeJA处理后,BS141开颖率当天达到最大,比对照高出31.45个百分点,第2天开始显著低于对照,第4天-第5天与对照没有显著差异。在开颖率最大的时候授粉,可使BS141异交结实率比对照提高24.77个百分点。MeJA处理后BS141的日开花高峰期主要集中在13:00,而对照较分散。上午10:00统计BS141柱头外露率,发现MeJA处理的BS141柱头外露率在5 d内均低于对照。MeJA处理的BS141每日最大开颖角度整体低于对照。由此说明通过喷施外源MeJA,可使小麦光温雄性不育系开颖率在喷施当天达到最大,且开花高峰较集中,此时授粉可显著提高异交结实率,但喷施MeJA对柱头外露率和最大开颖角度作用不显著。

茉莉酸甲酯(MeJA)可以诱导作物开花习性。为进一步明确MeJA对小麦光温敏雄性不育系开花习性、浆片及异交结实的调控作用,于花后第2天对小麦光温敏雄性不育系BS141进行4 mmol·L-1MeJA浸穗处理,同时以浸水穗作为对照,研究MeJA对不育系每日开颖率、日不同时间开花变化、柱头外露率、开颖角度、浆片形态及异交结实的影响。结果表明,MeJA处理后,BS141开颖率当天达到最大,比对照高出31.45个百分点,第2天开始显著低于对照,第4天-第5天与对照没有显著差异。在开颖率最大的时候授粉,可使BS141异交结实率比对照提高24.77个百分点。MeJA处理后BS141的日开花高峰期主要集中在13:00,而对照较分散。上午10:00统计BS141柱头外露率,发现MeJA处理的BS141柱头外露率在5 d内均低于对照。MeJA处理的BS141每日最大开颖角度整体低于对照。由此说明通过喷施外源MeJA,可使小麦光温雄性不育系开颖率在喷施当天达到最大,且开花高峰较集中,此时授粉可显著提高异交结实率,但喷施MeJA对柱头外露率和最大开颖角度作用不显著。

Methyl jasmonate (MeJA) can induce flowering habits. In order to further elucidate the regulatory role of MeJA on the flowering habits, lodicule morhpology, and outcrossing seed setting rate of photo-thermo sensitive male sterile lines of wheat, this study immersed the wheat line BS141 with 4 mmol·L-1 MeJA at 2 days post-anthesis, using water-immersed spikes as a control. The effects of MeJA on the daily anthesis rate, temporal variations in flowering, the glume opening rate, anthesis angle, lemma morphology, and outcrossing seed setting were investigated. The results demonstrated that upon treatment with MeJA, the glume opening rate of the BS141 peaked on the day of treatment, showing an increase of 31.45 percentage points compared to the control group. However, starting from the second day, this number was significantly lower than that of the control. From the fourth to the fifth day, there was no significant difference compared with the control. Pollination at the time when the glume opening rate was the highest increased the outcrossing seed setting rate of BS141 by 24.77 percentage points compared with the control. The peak flowering period of the MeJA-treated BS141 was predominantly concentrated at 13:00, whereas the control was more dispersed. The stigma exsertion rate of BS141 was statistically analyzed at 10:00 a.m. It was found that the stigma exsertion rate of BS141 treated with MeJA was lower than that of the control within 5 days. The overall maximum daily opening angle of BS141 treated with MeJA was lower than that of the control group. Therefore, by spraying exogenous MeJA, the glume opening rate of wheat photo-thermo sensitive male sterile line could be maximized on the day of spraying, and the flowering peak was relatively concentrated. At this time, pollination could significantly increase the outcrossing seed setting rate. However, spraying MeJA had no significant effect on the stigma exsertion rate and the maximum opening angle.
