Abstract


In western Henan province Apple optimum growth area, the cultivation area and production accounting for apple cultivation area in Henan Province, and 38.6% and 40.7% of the total production, but too large proportion of late-maturing varieties, harvest concentration, affecting the production of apples benefits. This test is designed to filter out a few for the development of the region as early as mid-maturing high-quality varieties, can make full use of the advantage of \In this paper, Apple (Malus pumila Mill) as the object of study, from screening in many domestic and foreign apple new varieties introduced the precocious high quality early McNair, Bella, Feng Yan Meng Fujimaki, Anna, Royal Gala , Early Red, Italy, the United States on the 8th, Red Tsugaru, Arima, Liaoning volts, cloud early as crown, Yun Fu, New Jonagold Jonagold, Golden Delicious, cloud Xu, Tin Wang No. 1 Starkrimson Red Chief , Warri spur 22 as test materials, the growth of climatic conditions, biological characteristics, the appearance of the fruit quality, internal quality fruit anatomical structures of the investigation and research, the results are as follows: 1. By Luoning County, the climatic conditions of the investigation, the results show that the region's climatic conditions suitable for growing apples, Apple's suitable area. Ecological adaptability through appropriate investigation and observation of three years, the results showed that: 22 varieties of normal growth and development in the region, growth with good results, five varieties bear fruit in the first year after planting, 15 varieties flowering results in the second year after planting, 22 varieties in all three years to bear fruit, Fujimaki No. 1, Royal Gala yields reached 2658.13 kg/666.7 m ~~ 2,2898.42 kg/666.7 m to 2 with early and high yield characteristics and off-season supply market advantage. Liaoning Province, fruit maturity ahead of 15 ~ 20 d, short growth period in only 50 d. Saplings vigorous vegetative growth and long sticks are more characteristic of multiple growth results mainly in the spur, continuous pick fruit ability, strong axillary flower buds results, these constitute the structure of the early and high yield foundation. From the quality of the fruit appearance point of view, observational study found that the ecological environment of the region, the smaller fruit shape index, fruit partial round; the most varieties coloring and finish high, with a high value of the goods. 4 on the internal quality of the fruit, fruit hardness tester, sugar meter, Mok Shu-Hsun total sugar assay, titration acidity, such as methods of all varieties of internal quality, the results show that: the hardness presented in maturing varieties early maturing varieties of law; soluble solids content compared with other major apple producing areas is not very different; sugar content close to or more than the apple sugar content of Liaoning Province. Pericarp structure from the point of view, in western Henan province tested 22 varieties, the lenticels density presents medium maturing variety is greater than the law of early maturing varieties; law in the lenticels size presents early maturing varieties than mid-maturing varieties; the thickness of the wax layer presents a medium maturing variety is greater than the law of early maturing varieties. 22 varieties of fruit appearance and shape, internal quality, storage, stress resistance and adaptability, market competitiveness, physiological, ecological, morphological index test analysis. Think Fujiki, precocious, early in the familiar Royal Gala in western Henan province cultivars suitable for the preferred varieties, cooked medium supplemented with a small amount of early U.S. 8 and precocious Early McNair. And on the basis of this study, put forward several suggestions to improve the production quality.
