This study is conducted to discover the relationship between the growth ta xanh coconut fruit and lipid accumulation in its endosperm. During the fruit development period, several criteria are determined, such as the fresh and dry weight of the crustal or seed, the amount of glucose, protein and lipid in the liquid and solid endosperm. The growth period of ta xanh coconut fruit is 12 months and is divided into four stages, lasting from fruit set to harvest. Each stage lasts about three months: (1) young fruit stage, (2) the growth fruit stage, (3) the growth solid endosperm stage (coconut meat), (4) the maturation and ripening stage. In particular, the young fruit period is the slow growth period of the fruit, followed by the second stage that is marked by a rapid growth of fruit in crustal and liquid endosperm (coconut milk). At the end of this stage, the liquid endosperm not only reaches the maximum size and weight but also contains the highest level of glucose and starch. During the third stage (7th - 9th month), the volume and content (glucose and starch) of the liquid endosperm remain stable. In this stage, the solid endosperm is formed from the liquid endosperm. The final stage is that of reducing the volume of the liquid endosperm whereas the embryo and solid endosperm grow significantly. Additionally, maximum lipid accumulation occurred in both liquid and solid endosperm.
The growth of Ta Xanh coconut fruit is divided into four stages: slow growth, rapid growth, mature and ripening. In the mature and ripening stages, lipid accumulation increased at the strongest level in the endosperm. This study was conducted with the purpose of studying the effects of plant growth regulators on the growth and lipid accumulation in copra (solid endosperm) from the mature to ripening stage in Ta Xanh coconut fruit. Fresh weight, dry weight and lipid content in solid endosperm after treatments with 1 mg/L NAA, 10 mg/L BA and 20 mg/L GA3 individually or in combination with ethrel were determined. Results showed that the treatment of 20 mg/L GA3 on the 8-month-old fruits increased the copra fresh weight and dry weight. Treatments of 1 mg/L NAA, 20 mg/l GA3 or 200-250 mg/L ethrel on the 10-month-old fruits increased the ratio of lipid in the copra of each fruit. Treatment of 200 mg/L ethrel had a positive effect on increasing of the fresh weight, dry weight and lipid concent in the solid endosperm of the 10-month-old Ta Xanh coconut after 1 or 2 weeks of combinated treatment of 1 mg/L NAA, 10 mg/L BA and 20 mg/L GA3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
