龙眼在我省南部地区花期一般都在4月下旬～5月中旬左右,这段期间经常遇到阴雨,对人工授粉育种工作很不利。为此,特进行本试验,观察龙眼花粉生活力及貯藏性与外界条件的关系,找出花粉的适当貯藏方法,为育种及人工授粉提高产量提供科学依据。现将试验经过与结果简述如下。 Longan in the southern region of our province are generally flowering in late April ~ around mid-May, during this period often encounter rainy weather, artificial pollination breeding is very detrimental. Therefore, we carried out this experiment to observe the relationship between pollen viability and storage conditions of longan and the external conditions, and find out the proper storage method for pollen, which provides a scientific basis for breeding and artificial pollination to increase yield. Now the test results and the following summary.
