Abstract

Pollen viability and in vitro pollen germination was examined in single and double types of Nerium cultivars. Maximum pollen viability per cent was recorded in the cultivar UHSBN-6 (97.90%) followed by the cultivar UHSBN-14 (95.68%) and least per cent was recorded in the cultivar UHSBN-24 (89.58) when methyl blue was used as a dying agent. Potassium iodide showed the maximum per cent pollen viability in the cultivar UHSBN-12 (95.66%). Further, maximum in vitro pollen germination was recorded in the cultivar UHSBN-19 (68.69%) in 15% sucrose with 100 ppm boric acid which was on par with the cultivar UHSBN-17 and UHSBN-29 (67.18 and 66.90% respectively). The cultivar UHSBN-12 recorded maximum in vitro pollen germination (77.12%) under Brew baker and Kwack medium which was on par with cultivars UHSBN-19 and UHSBN-30 (74.80 and 74.72% respectively). The results obtained from the present investigation can aid in planning crosses and establishment of Nerium hybridization programs using compatible cultivars.
夹竹桃Nerium (Nerium oleander L.)品种花粉活力及离体萌发评价
对单型和双型Nerium品种的花粉活力和离体萌发率进行了研究。用甲基蓝处理时,花粉活力最高的品种为UHSBN-6(97.90%),其次为UHSBN-14(95.68%),最低的品种为UHSBN-24(89.58%)。UHSBN-12的花粉活力以碘化钾最高(95.66%)。在15%蔗糖加100 ppm硼酸的条件下,UHSBN-19的花粉萌发率最高(68.69%),与UHSBN-17和UHSBN-29相当(分别为67.18%和66.90%)。品种UHSBN-12在Brew baker和Kwack培养基上的花粉萌发率最高,为77.12%,与品种UHSBN-19和UHSBN-30的萌发率分别为74.80%和74.72%。本研究结果可为拟合品种的杂交规划和拟合品种的建立提供参考。
