杂交榛开花结实特性观察试验研究

以引进27个品系的杂交榛为试验材料,系统观察各品系生长物候、花期物候和结实特性。结果表明:杂交榛在伊犁河谷的霍城试点于3月上中旬进入开花期,花期持续20 d左右;不同品系间花期存在差异,大多数品系雌花盛花期均比雄花盛花期晚1~6 d。受气温等因素的影响,在天山北坡的玛纳斯试点开花期比霍城试点晚10 d左右,花期短5 d左右。不同品系在不同试点的结实性能有所不同,霍城试点多数品系平均株产量比玛纳斯试点高。这为选择确定伊犁河谷及天山北坡经济带适宜种植的杂交榛优良品种,提供了科学依据。

Observation Test of Blooming and Bearing Characters of Hybrid Hazel

The experiment was conducted to study the blooming and bearing characters of hybrid hazel from the introduced 27 strains,which were used as test materials.The resutls indicated that the hybrid hazel in Ili River Valley began to flower in the middke ten days of Mar.which continued for about 20 days.It was found that there were differences of flowering period among the above strains.The full bloom stage of the female flower was late for 1-6 days,compared with that of male flower under the most conditions.The flowering period in Manas county test site was later about 10 days than that of Huocheng county.The average yield per plant in the test site of Huocheng county was higher than that of Manas county.Therefore it provided a scientific basis for selecting fine varieties of hybrid hazel which are adaptable to be planted in Ili River Valley and in the northern slope of Tianshan Mountains.
