Abstract

Growth plant is the result of transfer of solar radiation in to the photosynthetic processes of green leaf and transmission of photosynthates into increased biomass. Recently, many researchers have manipulated plant row-spacing and direction as well as plant populations within the row, to increase crop production through more efficient use of solar energy. A field experiment was conducted in North Kordofan State of Sudan, to investigate the effect of intra - row spacing (10, 20, 30 and 40cm) and planting stand (two and three plants per stand) on yield and yield components of Hibiscus sab- dariffa L. The results showed that, plant population had a significant effect on most of the attributes measured. Closer spacing increased the number of branches per plant, days to 50% flowering, days to 95% physiological maturity, number of calyces per plant, calyces yield (g/plant) and decreased final calyces yield (t/ha). Spacing of 20 cm and three plants per stand gave highest calyces yield (t/ha).

苏丹干旱热带雨养条件下植物种群对芙蓉生长和产量的影响

植物的生长是将太阳辐射转移到绿叶的光合过程中，并将光合产物转化为增加的生物量的结果。最近，许多研究人员通过控制植物行距和方向以及行内植物种群，通过更有效地利用太阳能来提高作物产量。在苏丹北科尔多凡州进行了大田试验，研究了行距(10、20、30和40cm)和种植林分(2株和3株)对木槿产量和产量成分的影响。结果表明，植物种群对测量的大部分属性有显著影响。较近的间距增加了单株分枝数、开花至50%的天数、生理成熟至95%的天数、单株萼数、萼产量(g/株)和最终萼产量(t/ha)。株距为20cm、单株3株时，花萼产量最高(t/ hm2)。
