Abstract

Pregerminated seeds comprising desiccation tolerant emerged radicles, processes for their production, and plants produced from such seeds.

Claims

1. Pregerminated seeds comprising desiccation tolerant emerged radicles wherein the emerged radicles contain elevated levels of sucrose relative to non-desiccation tolerant emerged radicles of the same plant species and wherein said desiccation tolerant seeds have an overall moisture content in the range of about 35% to about 55% by weight of the seeds and are capable of resuming growth when planted.

2. Pregerminated seeds according to claim 1 wherein said seeds have been stored at ambient storage conditions.

4. Pregerminated seeds according to claim 1 wherein the seeds are selected from plants of the group consisting of Alliums, Antirrhinums, Begonias, Brassicaceae, Capsicums, Cucurbitaceae, Lycopersicons, Cyclamens, Betas, Dianthuses, Gazanias, Gerberas, Impatiens, Lobelias, Nicotianas, Pelargoniums, Petunias, Phloxes, Primulas, Raphanuses, Salvias, Solanums, Tagetes, Verbenas, Vincas, Violas, Apiums, Chicoriums, Daucuses and Zinnias.

5. Pregerminated seeds according to claim 1 further comprising a seed coating.

6. Pregerminated seeds according to claim 1 wherein the desiccation tolerance is located in the hypocotyl region of the radicle.

15. Pregerminated seeds according to claim 1 wherein the seeds are Impatiens seeds.

3. Pregerminated seeds comprising desiccation tolerant emerged radicles wherein the emerged radicles contain elevated levels of sucrose relative to non-desiccation tolerant emerged radicles of the same plant species and the moisture content of said desiccation tolerant seeds lies in the range of about 4% to about 12% by weight of the seeds and are capable of resuming growth when planted.

7. Pregerminated seeds according to claim 3 wherein the seeds are selected from the group consisting of, Allium, Antirrhinums, Begonias, Brassicaceeae, Capsicums, Cucurbitaceae, Lycopersicons, Cyclamens, Betas, Dianthuses, Gazanias, Gerberas, Impatiens, Lobelias, Nicotianas, Pelargoniums, Petunias, Phloxes, Primulas, Raphanuses. Salvias, Solanums, Tagetas, Verbenas, Vincas, Apiums, Chicoriums, Daucuses, and Violas.

8. Pregerminated seeds according to claim 3 further comprising a seed coating.

9. Pregerminated seeds according to claim 3 wherein the seeds are Impatiens seeds.

10. Pregerminated seeds according to claim 3 wherein the seeds are Pansy seeds.

16. Pregerminated seeds according to claim 3 wherein said seeds have been stored at ambient storage conditions.

17. Pregerminated seeds according to claim 3 wherein the desiccation tolerance is located in the hypocotyl region of the radicle.

11. Pregerminated seeds comprising desiccation tolerant emerged radicles and having an overall moisture content in the range of about 35% to about 55% by weight of the seed wherein the embryos of the seed have an elevated sucrose level relative to the embryos of pregerminated seeds with non-desiccation tolerant emerged radicles of the same plant species.

13. Pregerminated seeds according to claim 11 wherein the seeds are salaried from the group of seeds consisting of Impatiens, Viola, Pansy and Cyclamen.

12. Pregerminated seeds comprising desiccation tolerant emerged radicles wherein the moisture content of said seeds is in the range of about 4% to about 12% wherein the embryos of the desiccation tolerant seeds have an elevated sucrose level relative to the embryos of pregerminated seeds with non-desiccation tolerant emerged radicles of the same plant species.

14. Pregerminated seeds according to claim 12 wherein the seeds are selected from the group of seeds consisting of Impatiens, Viola, Pansy and Cyclamen.
