Dry Matter Partitioning in Four Potato Varieties

Abstract

Abstract

An experiment was conducted at the research field of the department of horticulture, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, during the potato growing season of 2013–14 with four potato varieties viz. Asterix, Cardinal, Diamant and Granola to study the pattern of partitioning dry matter at different days after planting (DAP). Results revealed that at 30 DAP; maximum dry mass was partitioned to leaves and minimum to tubers, in all varieties. At 40 DAP, maximum dry mass was found to be partitioned to leaves followed by tuber, stem and roots. But at 50 DAP and onwards, higher dry matter was partitioned to tubers followed by leaf, stem and roots. Dry matter distribution to the tubers was found maximum between 40 and 60 days in all the varieties. More than 80% dry matter was partitioned to tubers at 80 DAP in all varieties. Granola distributed the highest (more than 75%) dry matter to tubers at 70 DAP but it obtained the lowest dry matter accumulation per plant. In other varieties, about or more than 80% dry matter was partitioned to tuber at 80 DAP. The variety Granola may be harvested within 70–80 days after planting and the other varieties after 80 days of planting.
