A seed is a plant part that can grow into a new plant. It contains three basic parts: the embryo, a supply of nutrients for the embryo, and the seed coat.

A seed also has a number of other features that allow it to spread and colonize new areas. Some seeds have fleshy appendages that entice animal dispersers to eat them; others have hooks, barbs, or sticky hairs that attach to animal fur or feathers.

The Ovule

The ovule is the reproductive organ of flowering plants that contains an egg cell that develops into a seed. It is found inside the ovary in angiosperms and attached to the inner surface of a female cone in gymnosperms.

Ovules consist of a megasporangium surrounded by one or two layers of tissue called integuments. The haploid female gametophyte or megagametophyte within the ovule produces spores that grow into embryo cells and eventually become a seed (Figure 1).

There are many different types of ovules, including orthotropous, anatropous, hemi-anatropous, campylotropous, amphitropous and circinotropous. In the orthotropous type, the chalaza, nucellus and micropyle are all aligned to the funicle.

In anatropous and hemi-anatropous ovules, the ovule body is straight while in the amphitropous and campylotropous ovules, the body is curved around. Finally, in the circinotropous ovule, the micropyle points upwards. This is the most common ovule orientation in flowers. It is also the only orientation that allows fertilization to occur, since sperm enter through the micropyle.

The Seed Coat

In higher plants, after fertilization, the ovule develops into a seed that is enclosed in a protective layer. This layer, called the seed coat, protects the embryo and endosperm.

During embryonic development, the two parts of the seed, the embryo and the endosperm, must communicate with each other. This coordination is essential for the success of a successful seed.

The development of the embryo involves one cotyledon in monocots and two cotyledons in dicots (see Chapter 2, Section 5). Both are positioned closely against the upper endosperm which provides food for the growing embryo.

The embryo and endosperm are surrounded by the seed coat which acts as a channel for transmitting environmental cues to the interior of the seed. This is an important function as an impenetrable seed coat would exclude the sensing of external environmental cues.

The Embryo

The embryo is a tiny, undeveloped part of an organism. It is distinct from the other parts of a body and has the genetic and epigenetic disposition to develop itself to the next mature stage along the path of human development.

The development of a human embryo starts at fertilization, when an egg is paired with sperm cells. The zygote divides several times to form a ball of cells that travels down the fallopian tubes into the uterus, where it eventually implants.

Once implanted, the embryo develops through a series of critical stages of growth and development: gastrulation, neurulation, and organogenesis.

Embryology is an important component of medical education. The content and presentation of this subject depends on the curricular objectives and goals of individual schools.

The Seedling

Seeds are the most common method of plant propagation and reproduction. They contain genetic material from the parents and are dispersed through a variety of mechanisms, such as wind, animals, insects, and water.

When a seed is germinated in the soil, it undergoes a series of developmental and growth events that lead to the development of a plant. These events include the germination of the seed coat, the initial opening of the cotyledons and the formation of photosynthesis.

Once the cotyledons open, they provide an opportunity for the first light-induced photosynthetic events. These events are regulated by complex molecular and biochemical processes, involving profound reprogramming of the genome.

During this early stage, the seedling uses the reserves stored within the seed to support its early growth. These reserves may be in the form of starch grains, protein granules, or lipid droplets.

There are many different kinds of cannabis seeds available on the market. But the two most popular varieties are feminized and regular.

Feminized seeds lack male chromosomes, whereas regular seeds contain full complements of both sexes. This makes them ideal for breeding purposes and ensuring superior clones.

Stable Genetics

When a breeder creates a new strain, they have to work very hard to stabilize the genetics of the ideal phenotype. This process can take years. It requires a lot of patience and hard work, but the end result is a high-quality strain with some of the most desirable cannabis traits.

Stable seed varieties are often made with a variety of techniques, such as backcrossing (BX1 or S1 seeds). This technique selects a parent plant that has the desired trait and then crosses it with a male plant. It can be repeated as many times as needed to produce an offspring that is similar to the original clone.

This process can be expensive and time-consuming, but it is well worth the effort. In the long run, it will make the resulting strains more stable and a better source of new options for growers and consumers alike. It is also more likely to produce a consistent strain with the traits the breeder sought out.

Less Expensive

If you’re looking for high-quality cannabis seeds, it pays to pay a bit more. These higher prices are worth it, as they reflect the breeder’s years of experimentation in creating stable genetics that produce excellent clones.

If a cultivator can afford to do so, it’s often wise to buy organic seeds for their garden or lawn. They’ll typically cost more than conventional seeds, but they’re better for the environment and are a smart way to cut down on your environmental impact.

If you’re just starting out, feminized seeds may be the way to go. They’ll make cultivation easier, allowing you to practise and perfect your skills before moving on to regular seeds and breeding new strains.

More Vigorous

There is a long-standing tradition among growers to value the vigour, variety and purity offered by regular seed. The ability of these seeds to produce heavy harvests on a consistent basis is key to the success of many growers.

The vigor of seeds is affected by several factors, including germination, maturation, storage and aging. These conditions, in turn, can be influenced by moisture stress, nutrient deficiency and temperature.

This means that seeds grown under certain circumstances may not germinate properly or result in weak seedlings, collectively known as ‘poor-vigor seed’. The vigor of seeds also depends on their genetics.

Cannabis seeds are a great way to get your daily protein and fibre. They also have a number of other nutrients that help to keep your body in tip-top shape, including vitamins and minerals.

These seeds are a great choice for people on a low-calorie diet. They contain high levels of Omega- 3 fatty acids, which can improve the health of your heart and reduce the risk of blood clots.

Feminized

Feminized cannabis seed is a type of marijuana seed that has been bred to produce only female plants. It is a very valuable asset for commercial growers, as it eliminates the need to worry about accidental pollination from male plants.

It is also a good choice for those new to growing cannabis. The only drawback is that feminized seeds take a longer time to germinate than regular seeds, so you will need to be patient.

You should keep your feminized seeds at an ambient temperature during the sprouting process. As with regular seeds, high-intensity light is not recommended for this stage as the plant is not yet able to process it.

The optimal growing temperature for feminized cannabis is between 21degC and 25degC. This is because extremes can cause stunted growth and other problems.

Regular

Regular cannabis seeds are seeds that have been crossed between male and female marijuana plants. While they look identical to feminized seeds on the outside, they aren’t.

This is a key difference between the two, and it’s important for beginner growers to understand this. They’ll need to know how to tell a plant whether it’s male or female in order to make the best possible decision for their growing needs.

Generally, regular seed strains are more resistant to pests and fluctuating conditions than feminized seeds. They are also more likely to produce stable phenotypes and cultivars.

There are many reasons why some cannabis growers choose to use regular seeds over feminized ones, but ultimately, it’s up to the grower to decide which kind of seed is most suitable for their needs.

With the right knowledge, you can start enjoying a better crop of your favorite strains!

Autoflowering

Autoflowering cannabis seed is a strain that begins flowering after a predetermined period of time. This is unlike their photoperiod-dependent counterparts, which flower in response to the hours of daylight.

Typically, autoflowering seeds are hybrids containing either sativa or indica genetics with a species called ruderalis, which is native to Siberia and surrounding areas. Ruderalis plants naturally flower according to their internal clock, rather than in response to the hours of sunlight.

These hybrids are often easy to grow and require minimal attention, making them the perfect choice for beginners in marijuana cultivation. However, they are also popular with experienced growers who want easy-to-maintain, robust plants.

Since autoflowering seeds don’t rely on the hours of light to start flowering, they can be grown indoors and outdoors all year round. This allows cultivators to fit several harvests into one season, and it can be a great choice for those who have limited space or want discreet growing operations.

CBD

Cannabis seeds are an excellent source of CBD. They also contain omega-3 and omega-6 fatty acids, antioxidants, fiber, chlorophyll, and immune-stimulating secondary plant compounds.

Hemp seed oil is a type of cannabinoid extract derived from the hemp plant. It contains less than 0.3% THC, which means it won’t get you high.

Although hemp seed oil doesn’t contain significant amounts of CBD, it is still a good source of this powerful cannabinoid. Hemp oil can be used for a number of health benefits, including to boost heart health and fight cancer.

CBD can be ingested orally, applied to the skin, or inhaled. It can also be used in conjunction with other supplements or medicines to treat a variety of conditions.

However, some people may experience adverse reactions to CBD-based products. This is especially true if they are taking certain medications, have a history of gastrointestinal issues, or are pregnant or breastfeeding. Always consult your physician before trying any new dietary supplement or medication.
