 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Total Nonstructural Carbohydrate and Total Nitrogen Content in Leaves and Terminal Shoots of Mango (Mangifera indica L.) var. Nam Dok Mai throughout the Year) ผู้เขียน: Sirichai Kanlayanarat,  ดร.สุรนันต์ สุภัทรพันธุ์, ศาสตราจารย์ , Chalongchai Baabprasert สื่อสิ่งพิมพ์:pdf AbstractSeasonal changes in total nonstructural carbohydrates and total nitrogen contents in leaves and terminal shoots of mango (Mangifera indica L.) var ‘Nam Dok Mai’ were studied at every 4 weeks interval during June 1978 to May 1979. Total nonstructural carbohydrates in leaves and terminal shoots were found increased at two peaks, first in June, before the flush of new shoots and second in January, before flowering. The nitrogen contents in leaves and terminal shoots were high during the period from June to December, then decreased rapidly. In early January, total nonstructural carbohydrates were increased with the decreased in total nitrogen this phenomena was at the same period of flower initiation. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Seasonal Changes of Nitrogen, Phosphorus and Potassium Contents in Leaves and Terminal Shoots of Mango (Mangifera indica L.) var. 'Nam Dokmai') ผู้เขียน:Sirichai Kanlayanarat, ดร.สุรนันต์ สุภัทรพันธุ์, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe variations of nitrogen, phosphorus and potassium contents in leaves and terminal shoots of mango (Mangifera indica L.) var 'Nam Dok Mai' were studied in every 28 days interval at Pakchong Research Station, Kasetsart University, Changwat Nakhon Ratchasirna during 1978-1979. Nitrogen and phosphorus contents in leaves and terminal shoots were high before flowering and low during flowering and fruit growth periods. The levels of nitrogen and phosphorus decreased with the increase in age of leaves and terminal shoots. The changes of potassium content in leaves and terminal shoots did not relate to any particular pattern. |
