摘要

摘要在1983 ~ 84年花开花80%的季节,以100 mg l / 1的4-氯苯氧乙酸(4-CPA)喷施于径流中。4-CPA处理对收获产量无影响。果实的大小显著增加,因为果实中有更多的小核果。无论昆虫授粉水平如何,4-CPA均能增加小核果数。4-CPA喷施植株的果实成熟时间比未喷施植株晚一周,但收获期长度不变。

Boysenberry: Effect of 4-chlorophenoxyacetic acid on yield components and maturity
Abstract Boysenberry (Rubus hybrid) plants were sprayed to run-off with 4-chlorophenoxyacetic acid (4-CPA) at 100 mg litre-1, in the 1983–84 season, when 80% of flowers had reached anthesis. Harvested yield was not affected by 4-CPA treatment. Berry size was significantly increased because of greater numbers of drupelets in the berries. Drupelet numbers were always increased by 4-CPA, irrespective of the level of insect pollination. Fruit from plants sprayed with 4-CPA ripened one week later than fruit from unsprayed plants, but length of harvest period remained unaltered.
