 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : A Study of Stomatal Behaviour of Avocado ( Persea ameicana Mill. ) Leaves) ผู้เขียน: W. Pongsomboon, A.W. Whiley, S. Subhadrabandhu, R.A. Stephenson สื่อสิ่งพิมพ์:pdf AbstractImmature expanding avocado leaves are relatively sensitive to water loss under highly evaporative environments due to the lack of stomatal control. Stomatal conductance (gs) was determined on young expanding leaves of one-year-old avocado trees cv Hass growing in the glasshouse. The gs measurement was made in controlled air temperature room of 25oC both in the dark and light during leaf growing. Fully expanded leaf size was reached by about 30 days after emergence. Similar behaviours of stomata both in the dark and light were observed, suggesting to be due to an overriding effects of low vapour pressure deficit (VPD) on gs. |
