- 摘要:
- 为促进西兰花废弃茎叶汁液的资源化利用,以小青菜为供试材料,分别以培养皿培养和基质栽培的方法,研究不同稀释倍数下西兰花茎叶汁液发酵液对青菜种子萌发、幼苗生长、叶绿素相对含量、叶绿素荧光和光合作用的影响。结果表明,稀释10倍的西兰花茎叶汁液发酵液对青菜种子的发芽势、发芽率和根长等有明显的抑制作用,随着稀释倍数的增加,抑制作用解除,稀释50倍及以上的西兰花茎叶汁液发酵液对小青菜种子的萌发具有促进作用。盆栽试验结果表明,稀释50倍至100倍的西兰花茎叶汁液发酵液可促进叶绿素的合成,增加ETR(光合电子传递速率)、qP(光化学淬灭)、Y(Ⅱ)值(光合量子产量),从而促进小青菜光合速率以及植物生长,鲜重平均提高25.07%,其中稀释50倍处理下干重较对照增加了11.89%。因此,西兰花茎叶汁液发酵液在稀释50倍至100倍能够促进种子萌发和小青菜生长,尤其是50倍效果较好。
- Abstract:
- In order to promote the resource utilization of discarded stem and leaf juice from broccoli, the effects of fermentated juice of broccoli stem and leaf on seed germination, seedling growth, chlorophyll relative content, chlorophyll fluorescence and photosynthesis were examined by petri dish culture and substrate culture respectively. Brassica chinensis was used as the test material. The results showed that ten times dilution of the fermentated juice had obvious inhibitory effects on the germination potential, germination rate and root growth of Brassica chinensis. With the increase of dilution multiple, the inhibitory effect was removed, and 50 or more times of dilution of the fermentated juice could promote the germination of Brassica chinensis seeds. The pot experiment with substrate cultivation showed that 50 to 100 times of dilution of the fermentated juice could promote the synthesis of chlorophyll, increase ETR (photosynthetic electron transfer rate), qP (photochemical quenching) and photosynthetic quantum yield (Y(Ⅱ) value), thus promote the photosynthetic rate and plant growth. The fresh plant weight increased by 25.07% on average for 50 times to 100 times of dilution treatments compared with CK (treated with distilled water), and an increment of 11.89% in dry weight was observed with 50 times of dilution treatment. Therefore, the fermentated juice of broccoli stem and leaf can promote seed germination and the growth of Brassica chinensis when diluted to 50-100 times, especially 50 times.
