In 2013 , the genus Phalaenopsis source pod that have traveled in infinite for 15 days on the " Shenzhou-10 spacecraft " were take ad cover by technical experts for 7 years after the spacecraft landing place . 15 excellent individual plant support out from more than these 6000 “ space phalaenopsis ” . " After four stage of selection , these individuals , in general , showed strong disease resistor and light sustainment cycle . " Mrs. Zhang Aixia , deputy general manager of Zhenxing Agricultural Technology Co. , Ltd ( Hereinafter relate to as Zhenxing Co. , Ltd ) . , introduced that after further compare , the city will apply for new plant potpourri rights of these “ space genus Phalaenopsis ” and further can be consider as the main kind of high - end flowers exported abroad .
On June 11 , 2013 , a phalaenopsis seed seedcase pick out and sent by Zhenxing Co. , Ltd participate space together with the " Shenzhou-10 spacecraft " and was bathed in cosmic rays for 15 day under weightless conditions . After returning to the earth , the pod was taken back to the sterile inoculation room of Zhenxing Co. , Ltd for culture . In the preceding 7 years , the phalaenopsis seeds combed out of that pod have undergo maternal selection , sterile culture , cultivation , and selection of flowering materialisation . A total of 15 plants were selected based on indicators such as flower type , flower coloring , flowering , pedicel height , and flower turn .
In the intelligent nursery of Zhenxing Co. , Ltd , three “ blank space genus Phalaenopsis ” are blossom brightly , and the pinkish petals are scatter out . " The flower diameter is large , broadly speaking between 12 and 14 cm , and they are all of the same colors . " Mrs. Zhang introduced that the biggest technical problem in phalaenopsis cultivation is the appropriate control and change of anthesis period , bloom type , and color . It only consume 10 month from culture to unfolding , which is two or three month short than established strains , and the seedling are full-bodied and scarcely get sick .
The reporter has learned that the scientific research and cultivation of these 15 phalaenopsis tenor has now enter the fifth stage , which is the leg of selecting single plant tissue polish and testing . At present , in addition to 3 song that are in the flowering point , 2 line are in the sustainment microscope stage , and the other 9 strains are in the tissue civilisation level . Compared with the ordinary phalaenopsis , the “ space phalaenopsis ” has a respectable appearing , with more heyday bud , and the flower diameter is about 1 curium longer than the average ones , and they are neatly arranged .
" In the next step , we be after to select one or two of these 15 strains and declare Modern variety rights . " Mrs. Zhang said that the successful cultivation of the “ quad phalaenopsis ” is a major breakthrough in the city ’s blank space training technology . It is foreseeable that the comprehensive output price required for genus Phalaenopsis cultivation will be greatly reduced , thereby achieving both increases in economic benefits and market place productiveness . As a raw line of merchandise of genus Phalaenopsis independently cultivated by Lianyungang City , the “ space genus Phalaenopsis ” will be " outstanding " in domestic and foreign prime securities industry .
