Use of Chlorophyll Fluorescence Parameters to Assess Drought Tolerance of Coconut Varieties

An investigation on the possibility of use of chlorophyll fluorescence to study the stomatal behaviour in plants under drought stress

Stomata play a key role in the control of plant water relations and photosynthesis. A rapid non-destructive method to study the stomatal behaviour in aerial parts of plants is important for researchers in plant sciences and agricultural fields. Stomata close in response to drought stress. Stomatal closure causes lower availability of CO2 inside the leaf and thus a decrease in the rate of carbox...

possibility of using chlorophyll fluorescence to assess the tolerance of a number of citrus rootstocks to waterlogging stress

changes in chlorophyll florescence is one of the physiological responses of plants to waterlogging stress. due to easily measured in field and its inexpensive and non-destructive characteristics, it is one of the best ways to assess different genotypes tolerance to stresses. in this experiment, trends of chlorophyll fluorescence index (fv/fm) of ‘satsuma’ mandarin (citrus unshiu) on seven roots...

Using Chlorophyll Fluorescence Imaging for Early Assessment of Photosynthesis Tolerance to Drought, Heat and High Illumination

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

Use of physiological parameters as fast tools to screen for drought tolerance in sugarcane

Use of physiological parameters as fast tools to screen for drought tolerance in sugarcane: Drought is one of the major limitations to plant productivity worldwide. Identifying suitable screening tools and quantifiable traits would facilitate the crop improvement process for drought tolerance. In the present study, we evaluated the ability of four relatively physiological parameters (variable-t...
