Distribution of mineral nutrients, dry matter and moisture contents and their correlations in different tissues and organs of wild Cerasus humilis during fruit development stages.

[Objective]The experiment was conducted to explicate the relationship and distribution of mineral nutrients, dry matter and moisture content during fruit development stages of Cerasus humilis, and to elucidate the mechanism of calcium accumulation in its fruits. [Method]The distribution of mineral nutrients (Cu,Zn,Fe,Mn,Ca,Mg and K) in fruiting bearing branches during the period of fruit development stages (young, hardening and maturity stages) was studied, and its relationship with dry matters accumulation and moisture content in wild Cerasus humilis tissues and organs was analyzed. [Result]The results showed the similar trend of distribution of Cu, Zn, Fe, Mn and Mg in different tissues and organs was analyzed by the dry matter. The descending order of nutrient distribution was as follows: young tipfruitphloemxylem. The distribution trend of K was found similar to the moisture accumulation trend, and the descending order was fruityoung tipphloemxylem. Ca was mainly found distributed in the younger tips followed by the phloem. The correlation of mineral nutrients distribution with dry matter and moisture content differed in different tissues and organs of Cerasus humili. A noticeable correlation was found in K accumulation. [Conclusion]The accumulation of dry matter and moisture content influenced the uptake and accumulation of mineral nutrients in different tissues and organs of Cerasus humilis. The potassium uptake and accumulation was found greatly correlated with the calcium uptake and accumulation in the fruits.
