The present invention provides methods for generating doubled haploid and/or haploid plants from microspores. In a presently preferred embodiment of the methods of the present invention, plant material is selected that bears reproductive organs containing microspores at a developmental stage that is amenable to androgenic induction. The microspores are treated by contacting the selected plant material with water and subjecting the selected plant material to temperature stress, and optionally to nutrient stress. Preferabl y the selected plant material is contacted with an effective amount of a sporophytic development inducer and an effective amount of an auxin and/or cell spindle inhibiting agent. Optionally, the selected plant material is contacted with an effective amount of a cytokinin and/or an effective amount of a gibberellin. The treated microspores are isolated, preferably by densit y centrifugation utilizing a solution of 0.3 M mannitol layered over a higher density solution of a sugar, preferably maltose. The isolated, treated micropsores are then cultured in a liquid nutrient suspension medium supplemented with at least one plant ovary or with an aliquot of plant ovary conditioned medium, until the microspores develop into embryoids. The embryoids are transferred to a regenerationmedium and incubated therein unti l the embryoids develop into plants. The resulting plants may be haploid or doubled haploid and may also be genetically transformed.

System for flue-gas hydrate-based desalination using LNG cold energy

A system for flue-gas hydrate-based desalination using LNG cold energy belongs to the field of hydrate technology application. The CO 2 in the flue-gas is captured based on the hydrate formation. Two stage formation chambers are set to improve the hydrate formation. The two steps to purify the hydrates respectively are the gas separation and the liquid separation. The two methods of hydrate dissociation to realize the recycling of the waste heat of flue-gas and the CO 2 are the heat-exchanged and the exhausted. The present invention realizes the integrated CO 2 capture and seawater desalination with a proper structure and a subtle system and solves the cold energy source for hydrate-based desalination by means of using LNG cold energy. The two stage formation chambers solve the capture of CO 2 in the flue-gas and guarantee the hydrate formation amounts. The two types of dissociation chambers decrease the heat emission by using the waste heat of flue-gas and realize the recycling and storage of CO 2 . The system will not be affected by the changes of seasons and environments and has a strong carrying capacity for the flue-gas source change. It is a system with great application value realistic.
