摘要

大麻(大麻sativa L.)是一种对外源生长调节剂影响敏感的物种,无论是在营养植物组织的处理还是在离体培养中。外源1-萘乙酸、吲哚-3-乙酸、2,4-二氯苯氧乙酸、动素、6-苄基氨基嘌呤(BAP)、赤霉素酸(GA3)、抗坏血酸和烟酸的浓度和剂量引起了USO 31植物中大麻素含量的变化。抗坏血酸、生长素和GA3显著降低大麻素含量,而烟酸和细胞分裂素显著增加大麻素含量。在烟酸和BAP的影响下,大麻素类化合物的含量在每三年的加工中都稳定地表现出较高的水平,并且至少遗传了一代后代。增加非精神类大麻素水平的另一种方法可能是用细胞分裂素BAP(浓度为40 mg/l,消耗速率为30 ml/m2,生长发育阶段为BBCH 51)处理营养植物组织,与高浓度烟酸相比,这显著增加了大麻二酚的含量,并且在较小程度上增加了四氢大麻酚的含量。处理显著提高了麻茎总长度、质量和纤维含量、种子产量和性别决定等选择性状。外源植物激素在调节大麻素积累、大麻植物形态发生及其生产力方面具有广泛的可能性。不同的大麻基因型可能对植物生长调节剂和浓度有不同的反应,这应该在每种情况下建立。

The influence of exogenous growth regulators on the cannabinoid content and the main selection traits of hemp (Cannabis sativa L. ssp. Sativa)
Hemp (Cannabis sativa L.) is a species sensitive to the influence of exogenous growth regulators, both in the treatment of vegetative plant tissues and in vitro culture. 1-naphthylacetic acid, indole-3-acetic acid, 2,4-dichlorophenoxyacetic acid, kinetin, 6-benzylaminopurine (BAP), gibberellic acid (GA3), ascorbic acid and nicotinic acid of exogenous origin in the studied concentrations and doses caused a change in the content of cannabinoids in plants of the variety USO 31. Ascorbic acid, auxins and GA3 significantly reduced the content of cannabinoids, whereas nicotinic acid and cytokinins increased it. Under the influence of nicotinic acid and BAP, a higher content of cannabinoid compounds was stably manifested during each of the three years of processing and it is inherited by at least one generation of descendants. An additional method to increase the level of non-psychotropic cannabinoids may be the treatment of vegetative plant tissues with cytokinin BAP (the concentration of 40 mg/l, the consumption rate of 30 ml/m2, the phase of growth and development BBCH 51), which, in contrast to high concentrations of nicotinic acid, significantly increased the content of cannabidiol, and, to a lesser extent, tetrahydrocannabinol. The selection traits of the hemp - stem total length, mass and fiber content, seed productivity and sex determination significantly increased under treatment. A wide range of possibilities for phytohormones of exogenous origin in regulating cannabinoid accumulation, morphogenesis of hemp plants and their productivity was confirmed. Different hemp genotypes may have different responses to plant growth regulators and concentrations, which should be established in each case.
