Abstract Growing citrus involves cultural treatments such as girdling and foliar potassium treatment to increase fruit size, yield quality. The aim of the study was evaluate effects single double stem girdling, nitrate (KNO 3 ) on leaves combinations these yield, size quality characteristics, leaf chlorophyll concentration nitrogen content, fluorescence (PSII) sugar content ‘Fremont’ mandarin v...

Intact sperm cells of Plumbago zeylanica were released from mature pollen grains near anthesis using osmotic shock with 20% sucrose. Sperm cell yields of up to 75% can be attained by differential centrifugation using a clinical centrifuge with concentrations of up to 8.8 x 10(6) cells/milliliter. Such ;gametoplasts' remain intact for up to 24 hours according to Evan's blue exclusion and can be ...

Due to climate change, multiple heat events are expected be an additional limiting factor that will adversely affect wheat production. The study aimed analyze the physiological response stress in four winter cultivars at different stages under greenhouse conditions during 2019. net photosynthetic rate, stomatal conductance, chlorophyll index, maximum quantum efficiency of photosystem II, fructo...

The effects of day temperature (DT), night (NT), and length (NL) were evaluated on the flowering responses heat-tolerant heat-sensitive poinsettia ( Euphorbia pulcherrima Willd. ex Klotzsch) cultivars Orion Red Prestige Red, respectively. Plants placed under 60 DT × NT NL treatments that consisted three (20, 24, 28 °C), four (16, 20, five (10, 11, 12, 13, 14 hours) for first 17 days experiment....
