This paper reported that the explants of bacteria-free cotyledons of Xinjiang muskmelon was trans-geneted treatment through Agrobacterium tumefaciens. Be directed against the yellowing leaves of adventitious buds after trangenic treatment

we engaged explorations from strain variance and conditions of genetic transformation and contents of mineral nutritious and intensity of illumination as well as temperation. The results indicated that the adventitious buds

from the explants of transgenic treatment

are yellowing universally by contrast. We took them respectively on the improve mediums of bud-growth which added Fe or Mg or B or K salt. After a period of time

the results indicated from morphological observation that the adventitious buds grew on the medium added Fe salt became green and green evidently

and so did the bud on the medium added Mg salt. The results indicated from micro and super-micro structures that the palisade cells of adventitious buds from medium added Fe salt contain many more chloroplasts

and also there are a lot of photosynthetic lamellaes are rich in the chloroplast.
