Resumo -O objetivo deste trabalho foi caracterizar aspectos morfológicos externos do fruto, semente, processo germinativo e plântula de Jatropha curcas. Em frutos e sementes foram avaliadas as características: dimensões, tipo, cor, textura, deiscência e número de sementes por fruto, presença de carúncula, formato do embrião e presença do endosperma. No estudo do desenvolvimento pós-seminal e diferenciação das plântulas, as sementes foram colocadas para germinar em meio de cultura MS (Murashige & Skoog). O fruto de Jatropha curcas é seco deiscente, capsular, tricoca, geralmente com três sementes e endocarpo lenhoso. A semente é ovalada, endospérmica, com envoltório liso e presença de carúncula. O embrião possui um par de cotilédones e eixo hipocótilo-radícula cilíndrico e reto. A germinação é epígea.Termos para indexação: ciclo biológico, germinação, morfologia, reprodução. External morphology of fruits, seeds and seedlings of physic nutAbstract -The objective of this work was to characterize the external morphology of the fruit, seeds, germination process and seedlings of Jatropha curcas. The fruits and seeds had the following characteristics evaluated: size, type, color, texture, dehiscence and number of seeds, presence of caruncle, form of the embryo and presence of the endosperm. To study the post-seminal development and differentiation of seedlings, seeds were placed to germinate in the MS (Murashige & Skoog) culture medium. The fruit of Jatropha curcas is of dry, dehiscent capsular type, generally presenting three seeds and woody endocarp. The seed is oval, endospermic, with smooth coat and the presence of caruncle. The embryo is composed of a pair of cotyledons and the hypocotylradicle axis is cylindrical and straight, with epigeal germination.

RESUMO:O objetivo deste trabalho foi estimar parâmetros genéticos de frutos, sementes e plântulas de Jatropha ribifolia (Pohl) Baill., subsidiando futuros programas de melhoramento e conservação genética. Foram selecionadas 20 matrizes da espécie e os frutos coletados em área de Caatinga, no Município de Jequié -BA / Brasil. Para descrição morfológica foram observadas características de 50 frutos e 50 sementes. Para germinação foi utilizado o delineamento experimental inteiramente casualizado com 20 tratamentos (progênie) e três repetições de 20 sementes. O fruto de J. ribifolia é seco, cápsula loculicida e septicida, endocarpo lenhoso e deiscência explosiva (autocórica). A semente é oval, endospérmica, de testa lisa, com diferentes colorações e carúncula presa na parte ventral. O hilo é visível e a rafe bem marcada longitudinalmente. A germinação é hipógea-criptocotiledonar. O tempo médio para germinação foi de 10 a 40 dias. As matrizes de J. ribifolia estudadas apresentaram variabilidade genética significativa para a maioria dos caracteres estudados.Palavras-chave: plantas medicinais, semi-árido, germoplasma, traços ABSTRACT: Genetic parameters of fruits, seeds and seedlings of Jatropha ribifolia (Pohl) Baill. (Euphorbiaceae). The aim of this study was to estimate genetic parameters of fruits, seeds and seedlings of Jatropha ribifolia (Pohl) Baill, subsidizing future breeding and genetic conservation programs. Twenty matrices of the species and the fruits collected in the Caatinga area in the city of Jequié -BA / Brazil were selected. For morphological description, the features of 50 fruits and 50 seeds were observed. For germination, completely randomized design was used with 20 treatments (progeny) and three replicates of 20 seeds. J. ribifolia fruit is dry and has loculicidal and septicidal capsule, woody endocarp and explosive dehiscence (autochory). The seed is oval, endospermic and has smooth testa and different colors, with caruncle attached to the ventral part. The hilum is visible and the raphe is longitudinally marked. Germination is hypogealcryptocotylar. The average time for germination was from 10 to 40 days. The matrices of J. ribifolia showed significant genetic variability for most of the studied traits.

“…Thus, assessment of trait based variability in J. curcas is a prerequisite for the screening and selection of agronomically elite genotypes which can later be exploited in breeding programs. To date, phenotypic diversity studies in J. curcas have mainly focused on the assessment of variability in seed traits and seed-oil content (Ginwal et al, 2005;Kaushik et al, 2007;Mazumdar et al, 2012). However, systematic studies involving other morphological and agronomically important traits in J. curcas germplasm such as plant height, canopy spread, male to female flower ratio, collar length, total seed yield and 100 seed weight for selection of elite planting material have been rare (Rao et al, 2008;Srivastava et al, 2011).…”

The morphological variation among Jatropha curcas L. populations from 29 different locations of NorthEast India was determined. Four populations from other parts of India were also incorporated in the study as an out-group. The morphological trait based analysis of J. curcas revealed large variation of quantitative traits among the populations. Of the six morphological traits used in this study, the highest variation (% coefficient of variation=23.19) was observed in floral sex ratio (M: F) while canopy spread (CS) appeared as the least variable trait (% coefficient of variation=1.67). Based on morphometric trait values, the three populations from Assam (IITJC15, IITJC24 and IITJC28) and one population from Arunachal Pradesh (IITJC7) emerged as superior when compared with the other populations. Both cluster and principal component analyses depicted that the populations IITJC19, IITJC21, IITJC22 and IITJC24 from Assam maintained maximum inter-cluster distance from the rest of the populations and are, thus, substantially distinct. The analyses also depicted that no clear demarcation can be made between populations from North-Eastern India and other areas on the basis of morphometric variability alone. Morphometric characterization of J. curcas populations leads to the identification of seven promising populations (IITJC7, IITJC15, IITJC19, IITJC21, IITJC22, IITJC24 and IITJC28) from North-East India which can substantially contribute to Jatropha breeding in the future. From the study of variance components and broad sense heritability, it was suggested that the selection of elite plants on the basis of M: F ratio, 100 seed weight (100SW) and total seed yield (TSY) in tree improvement programs is likely to be more successful.
