Regular seeds are a type of cannabis seed that contains both male and female genetic information. This means that they can produce either male or female plants, depending on a number of factors.
This means that they are ideal for breeders and those looking to preserve plant genetics in a vegetative state or develop new strains. They are also more stable than feminized seeds, making them suitable for asexual reproduction (taking cuttings).
The price of regular seed is determined by a number of factors. These include the quality of the genetics, supply and demand, the amount of THC in the strain, and legality in your location.
Expensive seeds are usually the best, and have undergone a more intensive development and research process. They are also more likely to have higher THC concentrations.
A seed lot consists of inert material such as dust, chaff, and seed coating; weed and other crop seed; and Pure Live Seed (PLS) of the desired species. Using PLS allows a more accurate price comparison between seed lots, and adjustment of seeding rate if necessary.
Gender is a social construct that is based on the roles, behaviours and attributes of women, men, girls and boys. This includes their beliefs, values and attitudes.
This social construction is influenced by many factors, including family, education and the media. It is learned and internalised by people from an early age, and can change over time.
While it is generally accepted that biological sex determines gender, research also points to other factors which may influence the way in which humans form their identities. This is known as the nature versus nurture debate, and it is often contested by both researchers and theorists.
For cannabis growers, the best way to separate male and female plants is by looking for sex changes as soon as the seeds start to grow. It will typically take between four to six weeks for these changes to show, and they can be spotted by checking nodes or growth points.
Typically, flowering time is determined by the length of daily exposure a plant receives to the sun (with the exception of Cannabis ruderalis species, which automatically flower). The actual flowering time of any given strain will vary significantly depending on your local conditions and growing method.
In other cultivated plants, flowering time plasticity has evolved in relation to biotic and abiotic changes to maximize reproductive success across a wide range of climates and seasons. Variations in key flowering time genes have also played an important role in the domestication of crops like wheat.
To elucidate the molecular mechanisms that control flowering time, we performed an RNA-seq screen on lines “4004” and “50” from the divergent selection experiment at generations G7 and G11. The compared expression levels of the C/L/P pathway flowering enhancers and repressors BrCIR1, BrTEM1, BrCRY2 and BrPRR5, as well as the V pathway flowering gene BrVRN1 were measured on shoot samples collected before vernalization. The results were mapped to an expression map and classified according to flowering enhancer/repressor criteria.
The yield of regular seed is determined by how much each plant produces in a given crop season. A variety of factors influence yield potential, including seed size and shape, environmental conditions, planting date and soil fertility.
Yield estimates are based on sampling and observation, and these measurements are subject to error. Even when excellent care is taken to select areas and plants for sampling, errors are common.
However, when used with careful attention, yield estimates are very useful in making crop management decisions. The most popular pre-harvest method is the Yield Component Method (Nielsen, 2019).
Seed sizes and shapes vary based on ear size, and kernels at the tip of the ear may not contribute to total yield as they have undergone stress during pollination. This can be especially true for small rounds from the ear tip, which can have lower quality than larger rounds. They are also subject to higher levels of stress when exposed to cold weather during their production.
