The paper deals with 46 species of plants covering 44 genera and 34 families used for curing bites by the tribes of Srikakulam district, Andhra Pradesh. Cucurbitaceae is the dominant family with 4 species followed by Fabaceae, Caesalpiniaceae, Mimosaceae, Asclepiadaceae, Verbenaceae, Apocynaceae, Loganiaceae, Menispermaceae, Euphorbiaceae with 2 species each and others. Herbs are more (16) followed by trees (11), shrubs (10), climbers (8) and a lone liane. Root is involved in 13 practices followed by whole plant (9), leaf (8), stem bark and seed (6 each), root bark (5) and others. For snake bite 23 species are exclusively used followed by 8 for scorpion sting, 4 for scorpion and snake bite, 3 each for dog bite and dog and snake bites, 2 for insect bite and others. Crotalaria laburnifolia and 7 practices were found to be new.
The present paper deals with the ethno-medico-botany of Srikakulam district of Andhra Pradesh. 20 plant species belonging to 15 families are enumerated with knowledge of tribals for their medicinal uses in curing malaria. Plant part used, vernacular name, method of preparation of the drug and the dose of administration are given.
Intensive cropping systems have led to an increase in the demand of the crucial nutrients in the soil. Thus, addition of essential inorganic and inorganic nutrients to attain the coveted soil status is necessary for the sustainable leaf production in mulberry. This study was conducted on a total of 1472 soil samples from conventional sericultural regions present in 8 districts of Andhra Pradesh, India. The soils were subjected to the chemical analysis to determine their soil reaction, salinity, and nutrient status including pH, EC, OC, available macro (N, P and K) and micro (S) nutrients. The perusal of the results indicated that out of the received soils, soil pH was recorded at desired levels (6.5-75) in 58% soils, low (<6.5) in 8% soils and high (>7.5) in 33% soils. Most of the cluster soils (99%) showed an ideal range of soluble salts (<1.0 dS/m). Organic carbon (OC) was low in 74% soils (<0.65%), medium (0.65-1.0%) in 21% and high (>1.0%) in only 5% soils. In case of essential macronutrients, available Nitrogen (N) recorded low in 50% soils (<250kg/ha), desired level in 37% (250-500kg/ha) and registered high (>500kg/ha) in only 13% soils. Phosphorous (P) and Potassium (K) were recorded high, >25kg/ha and >224kg/ha in 52% and 54% soils, medium level, 10-25kg/ha and 110-224kg/ha in 21 and 37%; whereas low, <10kg and <110kg/ha in 26% and 9% soils, respectively. In case of micronutrient sulphur (S), 61% of the cluster soils were registered rich in sulphur (>15ppm/ha), 25% showed the admissible range (10-15ppm/ha) whereas only 14% soils were recorded with low levels of S (<10ppm/ha) indicating that most of the cluster soils are rich in sulphur.
Two six‐parent sets of crosses, each consisting of three resistant inbreds and three susceptible inbreds, were grown under heavy natural infections of maize dwarf mosaic virus (MDMV) in two locations in Tennessee in 1968. Highly significant differences among genotypes were obtained in all experiments for reaction to the virus. White inbred Ga209 and yellow inbred T232 were the most resistant both as inbreds and in F1 crosses. Mean MDMV ratings for R ✕ R, R ― S, and S ✕ S crosses were 1.09, 1.78, and 3.41, respectively. The data showed that resistance to MDMV was largely dominant and was controlled by only a few major genes. Indications were that minor genes also were necessary for a high degree of resistance. General combining ability effects for reaction to MDMV were highly significant and were more important than specific effects. Significant specific effects were associated with crosses involving highly susceptible inbreds. Hybrids having high tolerance are obtainable from crosses involving these resistant inbreds. The data indicate that a backcrossing procedure can be used to transfer the resistance factors into elite lines. Alternating generations of backcrossing with selfing or sib‐pollination of resistant plants will facilitate incorporation of any minor genes necessary for a high degree of resistance. Some form of recurrent selection in populations having a degree of resistance also is suggested.
The paper deals with 49 species of plants covering 46 genera and 31 families used by the tribes of Srikakulam district, Andhra Pradesh for curing cuts and wounds. 26 practices were found to be less known.
