The Effect of Orobanche crenata Infection Severity in Faba Bean, Field Pea, and Grass Pea Productivity
Broomrape weeds (Orobanche and Phelipanche spp.) are root holoparasites that feed off a wide range of important crops. Among them, Orobanche crenata attacks legumes complicating their inclusion in cropping systems along the Mediterranean area and West Asia. The detrimental effect of broomrape parasitism in crop yield can reach up to 100% depending on infection severity and the broomrape-crop as...
متن کاملCharacterization of Resistance Mechanisms in Faba Bean (Vicia faba) against Broomrape Species (Orobanche and Phelipanche spp.)
Faba bean (Vicia faba) production in Mediterranean and Near East agriculture is severely constrained by broomrape infection. The most widely distributed broomrape species affecting faba bean is Orobanche crenata, although O. foetida and Phelipanche aegyptiaca are of local importance. Only moderately resistant cultivars are available to farmers. Rizotrons studies allowed the dissection of resist...
متن کاملGranular formulation of Fusarium oxysporum for biological control of faba bean and tomato Orobanche.
BACKGROUND Orobanche spp. represent a serious threat to a wide range of crops. They are difficult targets for herbicides, and biological control could provide a possible solution. This work therefore aimed to formulate mycoherbicides of Fusarium with adequate shelf life and virulence against Orobanche but safe to faba bean and tomato. RESULTS Only two isolates of Fusarium oxysporum Schlecht. ...
متن کاملChlorophyll Fluorescence Parameters and Chlorophyll Content in Mangrove Species Grown in Different Salinity
Leaf chlorophyll fluorescence parameters as well as chlorophyll content were compared in three dominant mangrove species grown in two zones with different salinity in the Bhitarakanika National Park. The accumulation of dry matter and chlorophyll content in leaves decreased under high saline conditions. Quantification and de-convolution of chlorophyll fluo-rescence transient into several phenom...
متن کاملChlorophyll a + b Content and Chlorophyll Fluorescence in Avocado
Tonnage (T), Simmonds (S) avocado trees, and TxS crosses were evaluated for differences in chlorophyll content and maximal quantum yield of photosystem II in sun and shade-type leaves. Total chlorophyll content by area (Chl a+bar) ranged from 984 mg m in TxS240 to 4320 mg m in Simmonds. Chlorophyll a/b ratio (Chl a/b) ranged from 9.8 to 5.5 in TxS238 and TxS243, respectively. Tonnage and Simmon...
