Effects Of S3307 On Tomato Seedling Growth, Bud Formation

Tomato seeds were soaked with S₃₃₀₇ in this experiment. The purpose was to study the effects of S₃₃₀₇ to the germination of seed and the growth of seedling. Meanwhile, the forming of alabasturum, the tolerance of seedlings and the node order of flowers were also researched. The result indicated:One. The germinating potentiality and germinating rate were differently extent inhibited by the use of S₃₃₀₇.Two. Because the contents of chlorophyll, soluble sugar were increased and photosynthesis and photosynthetic rate were enhanced, cultivating robust seedling and increasing output had a good basis .At the same time, S₃₃₀₇ could lowered the node order of first flower and shortened the presented stage of alabasturum. The above phenomena suggested that S₃₃₀₇ was contributed to the formation and maturity of flowers and the increasing of prophase yield.Three.The sprout height was notably lowered, the stem-thickness was increased and the ratio of shoot was risen. The test showed that it was preferable to cultivate robust seedling and improved the lodging-resistant capability in soaked S₃₃₀₇.Four. In dry condition, the contents of free proline vitamin C and soluble sugar were also increased by way of S₃₃₀₇ soaking. On the other hand, the MDA content and the electrolytic leakage of leaves were remarkably decreased and the resistance of seedlings was strengthened.Five. 5ug/g S₃₃₀₇ was the favorite choice to cultivate robust seedling and improve the tolerance based on the total effects .
