叶片是制造碳水化合物的主要器官,向日葵生长及结实所需要的有机质主要靠叶片制造供给。了解叶片生长的一般规律及其对产量的影响,在生产实践上具有很大意义。因此,我们以油用型品种派列多维克为材料,进行了这方面的初步研究。于7月8日播种,行株距80cm×30cm,分别在三对真叶期、花原基形成期、现蕾期、四分体期、开花期、终花期及成熟期对可见叶进行度量统计。可见叶系指叶柄长出
Leaf is the main organ for the manufacture of carbohydrates, sunflower growth and strong organic matter required mainly by the blade manufacturing supply. Understanding of the general rules of leaf growth and its impact on the yield, in the production of great practical significance. Therefore, we use the oil-based variety Pievic to make a preliminary study in this area. Were planted on July 8, and the row spacing was 80 cm × 30 cm. The leaf segments were observed in three pairs of true leaf stage, flower primordium formation stage, bud stage, tetrad stage, flowering stage, terminal flowering stage and mature stage respectively . Visible leaf refers to the petiole grows
