Indica vs. Sativa: What’s The Difference?

This selection draws on a huge gene pool and the possible F2 combinations are tremendous. Further independent selection and inbreeding of the best plants for several generations will establish two strains which are true-breeding for all the originally selected traits.

However, if it is important to preserve unique imported genetics, hybridizing may be inadvisable.

Types Of Marijuana - Sativa, Indica and Ruderalis

This is known as gene linkage, These genes are spaced along the same chromosome and may or may not control the same trait. It is readily apparent that in the wild this is not a likely possibility. Aneuploid Cannabis is characterized by extremely small seeds.

A cross using pollen from these flowers also produces feminized seeds. The intense green of chlorophyll usually masks the color of accessory pigments, Chlorophyll tends to break down late in the season and anthocyanin pigments also contained in the tissues are unmasked and allowed to show through.

The F2 generation is a great source of variation and recessive expression. If seeds result, they will produce hybrid offspring exhibiting some characteristics from each parent. Indoor lighting or greenhouses can be used to protect breeding stock from winter weather. The hypothetical cultivator began well by selecting the best seeds available and growing them properly.

Assume that we separate two true-breeding populations of Cannabis, one with webbed and one with compound-pinnate leaf shapes.

Pistils in Hindu Kush strains are quite often magenta or pink in color when they first appear. Indica strains tend to have a lot more myrcene than sativa strains, which is why they often produce body relaxation.

Despite some utility, this product has serious drawbacks, including its cost. Finally, in Cunningham v.

Sativa vs Indica; Know the Major Differences

The F1 offspring may have a slight tendency to produce a few staminate flowers under further environmental stress and these are used to produce F2 seed.

Seedling plants take up much less space than adults. What happened to the genes for webbed leaves contained in the webbed leaf parent? He submitted that the failure of the certificate of analysis to specify the level of THC found in the plant substance renders the certificate deficient in properly identifying a prohibited narcotic.

Additionally, very little bud grows towards the stalk of the marijuana plant, with the majority, if not all the useable plant material beginning to grow almost half way up the stalk of the plant.

I could find no authority for that proposition and in any event I believe I have amply demonstrated that the consumption of marijuana does cause harm, albeit and perhaps not as much harm as was first believed.

It grows up to 2 metres and its leaves are dark green, especially when compared to sativa. These environmental factors influence the phenotypic image of genotype, but the genotype of the individual is responsible for overall variations in gross morphology, including size.

Some use hormones instead to achieve the same result.37th ECDD () Agenda item Cannabis Page 3 of 41 Preface This update of cannabis and its medical use was commissioned by the Secretariat of the Expert Committee on Drug Dependence, Department of Essential Medicines and Health Products, World Health.
