Growing potato starting with true seed On this page I'm going to report my progress with growing potato vines, and producing tubers, starting with true seed. The nature of the potato flower and seed is such that the sexual pollination produces seed with very different features, even if no cross-pollination of a different cultivar is allowed.
This fact explains why farmers prefer to "clone" potato tubers, that is replant the tubers, rather than start vines with true seed TPS.
Starting vines with TPS is a gamble No time to grow TPS in For I'm planning to grow out Morada Ojuda and Dheera. Watch this YouTube documentary Many thanks to Jeff Baas, a Water potential of potato tissue videographerwho donated his time to document the Kenosha Potato Project in the summer of See for yourself what I learned about growing potato during a season of extreme drought, without access to water for irrigation.
The video runs for a full hour, starting in June and ending with the harvesting of late varieties in October.
About half way [31 min] I show you seed berries of the variety Dheera. Seed berries produce potato botanical seed [aka TPS]. Growing potato from seed produces new tuber varieties. YouTube Documentary This page has been updated May 13, with pictures of TPS started on Feb 26 - please scroll to the bottom to see the latest updates.
In his book Michael suggests to always let potato vines go to flower and develop the fruit. After trying for several years, finally I have some that have self-germinated. At the end of the season I'll add pictures of tubers grown from self-germinated TPS - these are vines that I recognize in my garden area where potato were growing last year - you can clearly tell if any potato vine has a tuber in the ground versus a vine that has germinated from seed.
I have records of which varieties were growing where this self-germinated vines are growing now. Alaska Red True Seed I have been growing potatoes since but in for the first time I found seed pods - what a wonderful surprise.
Well, in the spring I have started the Kenosha Potato Projectand I have planted several varieties that have set true seed pods about 10 out of 30 cultivars- see list below.
Perhaps the plants that are setting true seed pods are telling me that they are very happy with my biodynamically improved soil. Not all cultivars will produce True Seed for you! According to Will Bonsall the original SSE potato collection curator vines will produce seed pods depending on soil quality, day length and other unknown factors.
In my opinion the production of seed pods is the affirmation that the selection of a particular cultivar is correct for a particular garden. For the opposite, if the vines don't produce seed, perhaps they are NOT supposed to be grown in your region.
The seed pods look like cherry tomatoes and contain between and seeds similar to a tomato. The seed is removed from the pods in the kitchen with a food processor in a bowl of water.
The seed will drop to the bottom of the bowl, dried and stored like tomato seed. Storage in the freezer for a few weeks helps to accelerate the natural dormancy period. Three seed pods of Blue of Sweden - on the half inch background grid you observe a pod size of almost one inch across.
These are the largest seed pods of my collection, and the only pods that turn purple - all other seed pods range from light green to dark green. This is the seed I have harvested from a few dozen pods harvested from Russian Blue potato vines. If you have a green house you can start the seed earlier and grow the vines under lights See seed starting reports at the bottom of this page.
On a half inch background pattern observe mini tubers grown from seed started in December. In addition to the mini tubers, potato vine seedlings started from TPS in December are repotted in April for transplating outdoors in June.The objective of this lab is to measure the water potential of potato tuber tissues.
We will monitor water uptake or loss by tissues in different sucrose solutions to identify an isotonic solution with water potential equal to that of the tissue. Determination of the Water Potential of plant tissue This practicdal assessment is designed to determine the water porential of potato tissue or any suitable plant tissue.
Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects such as capillary action.
Plant body See diagram Parts of a plant You will need some small plants that have flowers, branches and roots. Bring them to the classroom.
Give one plant to each pair of students. Organization of the vascular tissue. Vascular tissue is organized into discrete strands called vascular bundles, each containing xylem and alphabetnyc.com stems, the vascular tissue is organized into many discrete vascular bundles.
On January 12, , a year old Californian wife and mother of three children died from drinking too much water. Her body was found in her home shortly after she took part in a water-drinking contest that was sponsored by a local radio show.
