Study On Burline Behaviour Of Parthenocarpy,Physiological Mechanism And Heredity Laws Of Eggplant

Parthenocarpy eggplant has the high applicant value on the breeding high quality variety,fitting to plant on safeguard, and solving fruits tend to bad. But so far there is no report about appliance on the parthenocarpy eggplant, and there is less study on the parthenocarpy eggplant behaviour,heredity rule and physidogical mechanism, in ordor to provide the theory thereunder for the breeding of parthenocarpy eggplant.This dissertation draw on the parthenocarpy strain and non-parthenocarpy strain to mensurate fruit setting behaviour,nutritional ingredient and hybridize. Main results showed as follows:1. The characteristic of parthenocarpy eggplant has been affected by environment and heredity. On the low temperature, the parthenocarpy eggplant has the well behaviour on fruit setting. But non-parthenocarpy eggplant has high shatter percentage and low fruit setting percentage. Compared to the non-parthenocarpy eggplant, the parthenocarpy eggplant has less seeds or no seeds.2. The best temperature is 25℃to 30℃about germination percentage of farina. The lowest temperature is about 15℃and the highest temperature is about 35℃. In the same condition, the parthenocarpy eggplant is better than non-parthenocarpy eggplant about the germination percentage of farina.3. Unmonpod is more weight than monpod the during parthenocarpy eggplant; parthenocarpy eggplant is smaller than non-parthenocarpy eggplant.4. Content of main components of non-structural-carbohydrare (NSC) decreased collectively but increased at anaphase in the fruit's growth. There has the different between parthenocarpy eggplant and non-parthenocarpy eggplant on the contents of soluble sugar,reduced sugar,dextrose,and dissolubility protein. And the contents on parthenocarpy eggplant are more than contents on non-parthenocarpy eggplant. That's show that parthenocarpy eggplantis has accumulated more nutritive substance than non-parthenocarpy eggplant on the period of ovary. 5.The parthenocarpy eggplant has more contents of IAA,ZR,IPA,ABA than the non-parthenocarpy eggplant on the different parts. That's show that IAA,ZR,IPA,ABA have the important affect in the fruit's growth.6. The heredity of parthenocarpy is correspondent with the additive- dominance-epistasis model and belongs to the recessive heredity.
