Many have faced the problem of carrot seed germination. You wait almost a month for germination, and the results are zero or single sprouts. Time is lost, deadlines are running out, we have to do reseeding. It is not a fact that the second attempt will be more successful than the first. What are the ways to increase the germination rate? Bitterness often appears in root crops. Where does solanine come from in finished products?
Why are carrots bitter?
The root vegetable is bitter for three main reasons:
• diseases manifested during storage;
• greening of "heads" in the beds
• damage from a carrot fly.
Let's take a closer look at each item.
During storage, various types of rot appear on carrots. Pathogens actively feed on sugars, releasing their metabolic products into the tissues of the root crop. This is where bitterness arises.
During watering or weeding in the beds, the tops of the roots are exposed. When exposed to sunlight, they turn green, accumulating solanine. Subsequently, from the surface, the alkaloid penetrates into the root crop, spreading bitterness.
Agrotechnical techniques
Proper care prevents the causes of bitterness. To do this, the following agrotechnical methods must be observed:
1. When processing carrot beds, carefully monitor the ground level. If necessary, huddle the rows or add soil to the roots, protecting them from exposure.
2. Harvest in dry weather, without waiting for the autumn lingering rains. Trim the tops, leaving hemp 1-1.5 cm without damaging the heads.
3. Sick, cracked, damaged, green specimens should be sent for recycling. They are not suitable for storage.
4. Acquire relatively resistant varieties to diseases: Losinoostrovskaya, Queen of Autumn, Vitamin, Moscow late.
5. Before laying in the cellar, dust the roots with ash or chalk. Store in dry sand, at a humidity of 80-90%, at a temperature not exceeding 2 degrees. A layer of sand will separate the roots, localize the foci of the disease.
6. During the growing season, the fight against carrot fly with the drug "Iskra" at the rate of 1 tablet per 10 liters of liquid. Repulsive solutions of bitter pepper, marigolds, wormwood disorient the pest, beat off the smell of the main culture.
How to accelerate seed germination?
Nature conceived to insure the carrots from adverse factors, saturated the grains with essential oils. They delay the flow of moisture inside. Therefore, under normal conditions, sprouts appear in 21-25 days.
To increase the percentage of germination, reduce the waiting time, several methods are used:
1. Soaking in a solution of growth stimulants "Energin", "Biohumus". The norm is according to the instructions. The peasants used ash in the old days. Two tablespoons are infused in a liter of liquid for a day. Planting material is added. Withstand 2-3 days. Filter through a sieve. Dry.
2. Digging in. Dry seeds are packed in a linen bag. A hole 15 cm deep is dug in the garden. The "bundle" is lowered, buried in soil. They put a pole to mark the place. The moist earth allows the grains to swell in natural conditions. After 2 weeks, a bag is taken out, the planting material is slightly dried on paper. Sowed on a garden bed in moistened rows. Sprouts appear in 1-1, 5 weeks.
3. Bubbling. Oxygenation takes place through the use of an aquarium aerator. Air activates growth energy, increasing germination. The seeds are poured into a jar, water is added. The device is lowered for 2 days. Change the water twice a day for fresh water. Clean liquid can be replaced with micronutrient nutrient solution. The processed grains are filtered through a sieve.
4. Cold procedure. Soak the seeds in a cloth. Put away in a plastic bag. Placed on the top shelf of the refrigerator for 4 days. Then incubated at room temperature for 2 days.
5. Hot water treatment. Liquid with a temperature of 50 degrees is poured into a thermos. Pour dry seeds. Close with a lid. Shake occasionally. Hold for 35-40 minutes. Strain through cheesecloth.
By performing simple techniques, you can avoid the accumulation of bitterness in root crops, accelerate the germination of tough-like carrot seeds to a minimum period. Free your time from repeated reseeding.

How To Accelerate Seed Germination?
Sometimes summer residents are faced with the need to germinate seeds as quickly as possible, and there can be a great many reasons for this. But not everyone knows how to do this. In fact, the modern summer resident has a lot of assistants in this important matter: some of them can always be found in the pharmacy, and another part - in his garden or even on the windowsill. The main thing is to choose the most suitable and most effective option

In the middle lane, root celery has to be grown through seedlings. In order for a vegetable to grow and ripen, it takes up to six months. And if you don't want to waste time, you need to have time to sow before the end of February - the first days of March
April Crops Of Early Crops
Many vegetable crops have already been sown for seedlings in the winter in early spring. And what to do with yourself in April, while eggplants and peppers with tomatoes are waiting for relocation to the beds? Is it really worthless to lose a whole month? Experienced gardeners know that this is one of the most important months of the year when you need to lay the foundation for getting your first vitamins from your garden. While vegetables with a long period of development are waiting for their turn, their free areas should be used for obtaining early crops. Sown
Beet Root Aphid - A Thunderstorm Of Root Crops
Beet root aphid is an ubiquitous pest that attacks quinoa and other swan plants in addition to beets. It is considered especially dangerous because in a relatively short period of time from May to October, it is capable of giving from eight to ten generations. As a rule, the number of these parasites increases markedly in July and August. The vegetation attacked by them withers and dies, which adversely affects the harvest of long-awaited root crops
Carrot Why. Non-standard Root Vegetables
Even experienced gardeners are faced with common phenomena on carrots, like cracking, having many twisted roots on one plant instead of one. The pictures of the seed packs show smooth, even roots. Why do ugly people grow up in real conditions, not like the "handsome" from the cover? Consider the causes and measures to prevent negative processes
