Systematics and Botanical Characteristics of Industrial Hemp Cannabis Sativa L

ABSTRACT

The systematic affiliation of Cannabis has been controversial for many years. Without a doubt, today we know that they belong to the order Rosales, family Cannabaceae, genus Cannabis, species – C. sativa L., with both industrial hemp (C. sativa L. var. sativa) and narcotic C. sativa L. var. indica. Hemp can be divided into several groups according to their genetic plasticity, allowing them to adapt to changing geographical and climatic conditions, and to almost any substrate and the division can be made using different criteria. The most important are: origin, length of vegetation period, content of cannabinoids (THC and CBD), mono- and dioequivalence.

A natural feature is the phenomenon of sexual dimorphism, which is common in the world of other plants. Dioeciousness is natural, and the monoecious forms of hemp grown are unstable.

Although the pharmaceutical use of hemp has been known for more than 5 000 years, new bioactive compounds are still being discovered. So the potential of this species is still inexhaustible and unfathomable.

摘要

大麻的系统性联系多年来一直存在争议. 毫无疑问，今天我们知道它们属于蔷薇目，美人蕉科，大麻属（De Backer等人，2009年，Rajput和Kumar 2018年），物种-C.sativa L.，同时具有工业大麻（C.sativa L.var.sativa）和麻醉性C.sativa L.var.indica（Grotenhermen 2002年，Tipparat等人，2012年，McPartland 2018年）. 根据其遗传可塑性，大麻可分为若干组，使其能够适应不断变化的地理和气候条件（Horne 2020），并且可以使用不同的标准对几乎任何基质进行划分. 最重要的是:;起源，植被期的长度，大麻素（THC和CBD）的含量，单体和单体等效性. 一个自然的特征是两性异形现象，这在其他植物中很常见. 雌雄异株是自然的，大麻的雌雄同株形式是不稳定的. 尽管大麻在医药上的应用已有5000多年的历史，但新的生物活性化合物仍在被发现. 所以这个物种的潜力仍然是取之不尽、用之不竭的.
