研究盆栽试验条件下采摘1次、2次处理及0、0.3、0.6、0.9 g/kg NaCl 4个胁迫水平(分别以S_0,S_1,S_2,S_3表示)对中华枸杞和黑枸杞幼苗生物量、维生素C、还原糖和氨基酸含量的影响。结果发现,不同采摘措施下,中华枸杞均以S_0、S_1水平下幼苗生物量较高、品质较优。采摘2次与采摘1次中华枸杞幼苗生物量均以S_0、S_1处理显著高于S_2、S_3处理,增加量分别为0.97~2.91,0.91~1.42、3.85~6.07 g/盆;维生素C含量都以S_1处理最高,分别为456、366、371 mg/kg;还原糖含量则分别以S_1、S_0处理最高,为3.16%、2.81%、4.41%;氨基酸含量均以处理S_2﹥S_1﹥S_0﹥S_3。黑枸杞采摘2次处理幼苗生物量分别以S_1、S_3处理最高,为6.24、6.02 g/盆;采摘1次处理仍以S_1处理生物量较高,为9.32 g/盆;其幼苗维生素C、氨基酸含量均以S_2﹥S_1﹥S_0﹥S_3或S_3﹥S_2﹥S_1﹥S_0;还原糖含量分别以S_0和S_3水平下最高,为3.35%、4.25%、4.02%。结果表明,采摘期与盐胁迫对黑枸杞幼苗生物量及品质的影响规律性不明显,但总体而言,高盐胁迫(S_2、S_3水平)对二者的影响要小于中华枸杞。
The effects of 1, 2 treatments and 4 stress levels of 0, 0.3, 0.6, 0.9 g / kg NaCl (S_0, S_1, S_2 and S_3 respectively) on the biomass and biomass of seedlings of Lycium barbarum and Lycium barbarum were studied. Vitamin C, reducing sugar and amino acid content. The results showed that, under different picking measures, the Chinese wolfberry S0, S_1 level higher biomass, better quality. The biomass of Chinese wolfberry seedlings picked twice and picked once were significantly higher than that of S 2 and S 3 treatments, respectively, with the increase of 0.97 ~ 2.91, 0.91 ~ 1.42 and 3.85 ~ 6.07 g / The highest content of S 1 was 456,366,371 mg / kg, while the content of reducing sugar was highest at S 1 and S 0, 3.16%, 2.81% and 4.41%, respectively. The contents of amino acids were all S 2> S 1> S 0> S 3. The biomass of seedlings treated twice with black medlar was the highest with S 1 and S 3 treatments, 6.24 and 6.02 g / pot, respectively. The biomass of the seedlings treated with S 1 was 9.32 g / S_0> S_3 or S_3> S_2> S_1> S_0. The contents of reducing sugars were highest at the levels of S_0 and S_3, which were 3.35%, 4.25% and 4.02%, respectively. The results showed that there was no significant effect on the biomass and quality of Black Wolfberry seedlings during the picking stage and salt stress. However, the effect of high salt stress (S 2 and S 3) on them was less than that of Chinese Wolfberry.
