请教lz，新千年的花期和什么是相同的可以互相授粉？（我看一个佐治亚州的资料说新千年自花不实，可用珠宝和绿宝石授粉）
另外明星的冷量需求好像比新千年还高，表现如何？
----------------------------------------------
(Pat.) Millennia has a chilling requirement of about 300 hours, so it blooms early in the spring. However, flowers on vigorous shoots may bloom much later in the spring. Approximate ripening date in lower south Georgia should be late April and early May. Millennia berry size is large to very large on well-leafed bushes that are not overloaded. The berries are grey-blue in color, but may lack firmness. Picking scar is good to excellent. Flavor is good, although it can be somewhat bland on overloaded bushes. Bush vigor is medium to high with a spreading bush habit. Millennia often sets an excessive number of flower buds so winter pruning may be needed for good leaf development in the spring. Leaf spot resistance is above average for southern highbush, but stem blight and root rot resistance is to poor. Because of fruit softnesss problems and disease problems it is not recommended for Georgia. Millennia is not self-fertile, so at least two other southern highbush cultivars with a similar chilling requirement should be planted in alternate rows with Millennia. Good choices might be Jewel and Emerald. Released from Florida in 2000.
*(Pat.) Star has a chilling requirement of about 400-500 hours so it blooms late enough to avoid some freezes. However, overhead irrigation is recommended for consistent production. Approximate ripening date in south Georgia is late April to mid May. Fruit are large to very large, and are fairly firm. Flavor is very good. Fruit may exhibit some cracking in wet weather. Bushes are fairly vigorous and upright-spreading in habit. Star usually has good spring leaf development. It requires cross pollination from other southern highbush cultivars for best production. O'Neal, Santa Fe, and Emerald should serve as good pollinizers. Star does not shed pollen well under high humidity conditions, so it should not be the sole pollinizer for other southern highbush cultivars. Star is susceptible to Septoria leaf spot. Recommended for south Georgia. Released by Florida in 1996.
